SEVERE WEATHER WARNING Nil
CAPE – Convective Available Potential Energy
CAPE Convective Available Potential Energy (CAPE) is measure of the amount of energy available for convection. CAPE is directly related to the maximum potential vertical speed within an updraft; thus, higher values indicate greater potential for severe weather.
Observed values in thunderstorm environments often may exceed 1,000 joules per kilogram (j/kg), and in extreme cases may exceed 5,000 j/kg. However, as with other indices or indicators, there are no threshold values above which severe weather becomes imminent. CAPE is represented on a sounding diagram by the area enclosed between the environmental temperature profile and the path of a rising air parcel, over the layer within which the latter is warmer than the former. (This area often is called positive area). However, when estimating thunderstorm probability one should also always have a look at the Lifted Index.
Cloud types (genera)
Clouds are grouped in three main classes, based on where they are located in the atmosphere – low, middle or high. This triple division of clouds is based on the range or altitude (etage, level) on which a cloud genus normally occurs. In addition the World Meteorological Organization (International Cloud Atlas, 1956) classifies 10 cloud genera (types) in three major groups (cumulus or heap clouds, stratus or sheet clouds, and cirrus or fibrous clouds) by criteria essentially based on cloud form. However, as the cloud form is influenced by the level or etage where the cloud formed both classifications lead to the same results.
Cloud types The ten fundamental cloud types are: cirrus (Ci), cirrocumulus (Cc), cirrostratus (Cs) – also known as the high clouds; altocumulus (Ac), altostratus (As) and nimbostratus (Ns) – the middle level clouds; cumulus (Cu), cumulonimbus (Cb), stratocumulus (Sc), and stratus (St), which are classified as low clouds.
Note that certain cloud types often extend into other levels: altostratus into high, nimbostratus into high or low; cumulus and cumulonimbus into both middle and high.
The cloud genera (types) are further subdivided into cloud species
Shelf Cloud
The shelf cloud is a low-level horizontal arcus-type accessory cloud that appears to be wedge-shaped as it approaches. It is usually attached to the thunderstorm base and forms along the gust front. The leading edge of the shelf is often smooth and at times layered or terraced. It is most often seen along the leading edge of an approaching line of thunderstorms, accompanied by gusty straight winds as it passes overhead and followed by precipitation. It is an extension of the main cloud, unlike the roll cloud. The underside is concave upward, turbulent, boiling, or wind-torn. Tornadoes rarely occur with the shelf cloud.
Cloud variety
A subdivision of cloud genera based upon transparency and the arrangement of cloud elemets. Cloud varieties are:
duplicatus (du) – more than one layer at different levels
intortus (in) – irregular or tangled
lacunosus (la) – thin cloud with regularly spaced holes, net-like
opacus (op) – completely masks sun or moon
perlucidus (pe) – broad patches with some (small) gaps allowing blue sky to be seen
radiatus (ra) – broad parallel bands convergind owing to perspective
translucidus (tr) – translucent enough to permit the sun or moon to be seen
undulatus (un) – sheets with parallel undulations
vertebratus (ve) – looking like ribs or bones
The standard abbreviations consist of the first two letters. None, one or more of the terms may be applied to describe an individual cloud type (genus).
Accessory clouds
picture An accessory cloud is a cloud accompanying or adjacent cloud mass to another cloud, generally smaller than the latter, and separated from its principal part, usually a major cloud genus (or type) or sometimes partially merged with it. A specific cloud may be accompanied by one or several accessory clouds. Accessory clouds are:
arcus (arc) – arch, shelf, roll or wall cloud
incus (inc) – anvil
mamma (mam) – pouches hanging from underneath main clouds
pannus (pan) – ragged shreds of cloud
pileus (pil) – cap cloud
praecipitatio (pra) – fall, precipitation reaching the surface, usually in the distance
tuba (tub) – funnel clouds
velum (vel) – thin layer of veil
virga (vir) – fallstreaks, trailing to the ground
and last but not least the banner cloud
The term El Nino means ‘Christ Child’ and was first used by Peruvian fishermen in the late 1800’s to describe the warm current appearing off the western coast of Ecuador and Peru around Christmas time. Today El Nino describes the warm phase of a naturally ccurring sea surface temperature oscillation in the tropical Pacific Ocean. When this warming occurs the usual upwelling of cold, nutrient rich deep ocean water is significantly reduced. Sometimes an extremely warm event can develop that lasts for much longer time periods. In the 1990s, strong El Ninos developed in 1991 and lasted until 1995, and from fall 1997 to spring 1998. This oscillation is associated with the atmosphere, and thus the term ENSO � which incorporates the southern oscillation phenomenon – is commonly used.
So how can you determine if an El Nino event is occurring today? Certain changes typically occur to both the atmosphere and ocean during periods of El Nino and La Nina, and thus if factors such as wind velocities, sea surface temperatures, surface air pressure and sea level are monitored these changes can be detected. Here are some things you can focus on in order to determine whether an El Nino is currently occurring.
Sea Surface Temperatures
During non-El Nino and non-La Nina conditions sea surface temperatures are approximately 6-8 degrees Celsius warmer in the western tropical Pacific than in the eastern tropical Pacific. These temperature disparities typically occur because the easterly trade winds that blow across the tropical Pacific move the warm surface water with them from east to west. Thus, you could look at SST data to determine whether an El Nino event is occurring at present, or not.
Trade Winds
During non-El Nino and non-La Nina conditions trade winds typically blow to the west across the tropical Pacific, but during an El Nino event the trade winds typically slacken or reverse. Thus, you could look at wind velocity and direction to determine whether an El Nino event is occurring at present, or not.
Other factors to consider when determining whether an El Nino event is occurring: during non-El Nino and non-La Nina conditions the sea level is typically 0.5m higher in the western tropical Pacific because the trade winds move water with them from east to west. This movement of water also causes the thermocline in the west to be deeper than in the east, and as result upwelling typically occurs in the eastern tropical Pacific. During an El Nino event the trade winds typically slacken or reverse as shown above and thus less water is moved from east to west, so SST, sea level and the thermocline all increase in the east.
The Southern Oscillation Index (SOI) can also be monitored and recorded, indicating when El Nino events are taking place. During an El Nino event the surface air pressure is typically higher in the western tropical Pacific, than in the eastern tropical Pacific. The (SOI) measures the monthly/seasonal fluctuations in surface air pressure differences at Tahiti and Darwin (Equation = Tahiti � Darwin), and thus the SOI usually has a negative value during an El Nino event.
Doppler radar
doppler radar The Doppler radar is a device that measures the Doppler shift in a radar beam reflected from an object’s motion towards or away from the radar aerial. This so-called ‘Doppler-effect’ is used in meteorological radars where the objects are water droplets on either side of a rotating mesocyclone, thunderstorm or tornado.
doppler radar Angular velocity can be calculated from the extent of the red shift on one side and blue shift on the other. This technology is used for the meteorological NEXRAD (Next Generation Radar) system to measure both, simple precipitation patterns and the severity of thunderstorms or the likelyhood of tornado development.
People often use the terms tornado and funnel cloud interchangeably. There is however a distinct difference. A condensation funnel is a tornado, not a funnel cloud, if either a) it is in contact with the ground or b) a debris cloud or dust whirl is visible beneath it. Funnel clouds have no detectable debris or damage at ground level. The same is true for waterspouts. If there is a dark spot appearing on the sea surface underneath a condensation funnel, than it is a waterspout. If not, it’s a funnel cloud.
Earth’s Atmosphere
The Earth is surrounded by a blanket of air, which we call the atmosphere. The atmosphere has no precise upper limit, but for all practical purposes the absolute top can be regarded as being at about 200 km. However, from a scientific point of view the atmosphere reaches up to 600-700 km. Thus we are only able to see – and feel – what occurs fairly close to the ground. The atmospheric air has over large parts a fairly stable composition of roughly 70% nitrogene, 21% oxygene and a variety of trace gases.
Life on Earth is supported by the atmosphere. The atmosphere absorbs the energy from the Sun, recycles water and other chemicals, and works with the electrical and magnetic forces to provide a moderate climate. The atmosphere also protects us from high-energy radiation and the frigid vacuum of space.
The structure of the atmosphere
The envelope of gas surrounding the Earth changes from the ground up. Four distinct horizontal layers have been identified based on thermal and convective characteristics (temperature changes), chemical composition, movement, and density. From the surface of the Earth upwards the layers are:
(a) The troposphere, in which convection is often prominent and in which most significant weather occurs, where temperature generally declines with height. It is extending to the tropopause at a somewhat variable height, generally about 11 km over middle and higher latitudes and 18 km near the Equator. This layer is known as the lower atmosphere.
(b) The stratosphere, in which there is much less vertical motion, and which extends from the tropopause to about 50 km at the stratopaus e. The lowest region of this layer is usually isothermal, but the temperature then increases with height.
(c) The mesosphere, in which there is once again more convection, extending from the stratopause to a height of about 86-100 km at the mesopause. In this region, the temperatures again fall as low as -93°C as you increase in altitude. The chemicals are in an excited state, as they absorb energy from the Sun. The regions of the stratosphere and the mesosphere, along with the stratopause and mesopause, are called the middle atmosphere.
(d) The thermosphere, extending from the mesopause to the effective limit of the atmosphere, at about 200-600 km. Temperatures in this region can go as high as 1,727°C. Chemical reactions occur much faster here than on the surface of the Earth. This layer is known as the upper atmosphere.
(e) The region above 700 km, at which height atoms may begin to escape into space is known as the exosphere.
On the basis of chemical composition the atmosphere consists of only two layers, the homosphere (largely identical with the troposphere, stratosphere and mesosphere) in which the composition is essentially constant, an the overlying heterosphere.
Specific ionization and photochemical processes occur in the ionosphere(encompassing part of the upper mesosphere and thermosphere) and the chemosphere and ozonosphere (both part of the upper stratosphere).
Beaufort Scale
The Beaufort wind scale is a standard scale, running from force 0 for calm to force 12 hurricane and above for the description of wind speed. Each value represents a specific range and classification of wind speeds with accompanying descriptions of the effects on surface features. It was originally developed as a system for estimating wind strengths without the use of instruments.
It was introduced in 1806 by Admiral Sir Francis Beaufort (1774-1857) of the British navy to describe wind effects on a fully rigged man-of-war frigate of the period, and it was later modified to include descriptions of effects on land features as well. It is currently still in use for this same purpose as well as to tie together various components of weather (wind strength, sea state, observable effects) into a unified picture.

Thunderstorms are local storms accompanied by lightning and thunder and a variety of weather phenomena, such as heavy rain, hail or – in winter – snow, high winds and sudden temperature changes. Thunderstorms originate when intense heating causes a parcel of moist air to rise from the earth’s surface into upper levels of the atmosphere, a process called convection. Thunderstorms are therefore also known as convective storms.
At any given moment, it is estimated there are 2000 thunderstorms in progress around the world. They occur most frequently in the tropics but are also common in the mid-latitudes.
Thunderstorm ingredients:
Thunderstorms need an ample supply of moisture, preferably in the lower and mid-levels of the atmosphere, as they are mainly powered by latent heat released as water vapour condenses.
Thunderstorms need unstable air, a temperature profile with warm air near the ground and cold air aloft. When an air parcel is given an initial push upwards it will continue rising without additional force. Thus thunderstorms are more likely in the spring and summer than in the fall and winter. The sun warms the ground, which warms the air near the ground. In spring the air aloft retains its winter cold and thus will be more unstable than in the fall when the air aloft retains its summer warmth.
Thunderstorms need a source of lift. This can be (1) differential heating when air near the ground is warmer than in upper levels, (2) orographical effects when air has to rise to pass a mountain ridge, (3) frontal boundaries when air masses of a different temperature clash, (4) drylines when air masses with differing humidity but similar temperatures clash and (5) Land/Sea breezes. Thunderstorms can get started by even faint air boundaries and thus sometimes seem to pop up out of the blue sky.
Thunderstorms are often accompanied by severe weather and lightning is among the biggest weather killers. However, less then one percent of all thunderstorms produce hail bigger than the size of a golf ball and/or strong downburst winds. Only a small fraction of severe storms actually produce tornadoes or waterspouts.
No place in Europe is completely immune from the threats of thunderstorms. Severe weather can strike at any place, and at any time. Thunder and lightning occur simultaneously but thunder is heard later than lightning is seen, as light travels faster than sound. A good measure of distance from a storm is 1 mi (1.6 km) for every 5 seconds between flash and thunder.
Thunderstorm Probability
The Lifted Index is a measure of atmosphere’s stability (or instability) and Meteorologists use it to determine the thunderstorm potential. It doesn’t accurately predict the intensity of every single storm, but it is a useful tool to estimate the atmosphere’s potential to produce severe thunderstorms.
“Parcels” (or bubbles) of air start to rise on their own if they are warmer than the surrounding air. This process is called convection. Consider an air parcel as it begins to rise through the atmosphere after being heated by the sun and the warming ground. The Lifted Index is defined as a rising parcel’s temperature when it reaches the 500 millibars level (at about 5,500m or 18,000 feet asl), subtracted from the actual temperature of the environmental air at 500 millibars. If the Lifted Iindex is a large negative number, then the parcel will be much warmer than its surroundings, and will continue to rise. Thunderstorms are fueled by strong rising air, thus the Lifted Index is a good measurement of the atmosphere’s potential to produce severe thunderstorms.
For example, if the rising parcel has an temperature of -5°C when it reaches 500 millibars, but the actual temperature at 500 millibars is -11°C, then the lifted index is -6 Kelvin (or K) indicating the potential for strong thunderstorms. However, there are no specific threshold values that correlate lifted index to thunderstorm severity. In general a negative Lifted Index indicates an unstable atmosphere, so the larger the negative number, the more unstable the atmosphere is, the stronger a thunderstorm could be. Lifted index values rarely go below -7.
Now, find out about the convection and thunderstorm probablility across the British Isles yourself. Have a look at WeatherOnline’s new Lifted Index maps. The table above will help you to ‘read’ the map and to estimate the thunderstorm risk.
Important ! The Lifted Index is not a measured quantity, it is only a parameter that is theoretically derived. If the Lifted Index is favorable for severe storms but other conditions are not met, then no storms may form at all.
The Lifted Index (LI)
RANGE IN K COLOR AMOUNT OF INSTABILITY THUNDERSTORM PROBABILITY
more than 11 BLUE Extremely stable conditions Thunderstorms unlikely
8 to 11 LIGHT BLUE Very stable conditions Thunderstorms unlikely
4 to 7 GREEN Stable conditions Thunderstorms unlikely
0 to 3 LIGHT GREEN Mostly stable conditions Thunderstorm unlikely
-3 to -1 YELLOW Slightly unstable Thunderstorms possible
-5 to -4 ORANGE Unstable Thunderstorms probable
-7 to -6 RED Highly unstable Severe thunderstorms possible
less than -7 VIOLET Extremely unstable Violent thunderstorms,
tornadoes possible
strong westerly winds at ground levels today, but cloud cover has meant sun has not been able to come out on top today, I expect temp not to exceed 34.5 today.
Sudden showers lashed several parts of the city on Saturday, bringing down the day temperature.
Several areas, including Aminjikarai, Egmore, Chetpet, Velachery and Adyar experienced thundershowers from the afternoon. Areas in south Chennai experienced more rains.
The automatic rain gauges in Taramani and Anna University recorded nearly one cm of rainfall till the evening. While the weather observatory in Meenambakkam recorded 1 cm of rainfall, Nungambakkam had registered only a trace of rain till 5.30 p.m.
Officials of the meteorological department said Saturday’s rainfall was due to local convective activity followed by a prolonged period of intense heat and said rain or thundershowers would occur in some areas during the evening or night on Sunday as well.

It is most often seen along the leading edge of an approaching line of thunderstorms, accompanied by gusty straight winds as it passes overhead and followed by precipitation. It is an extension of the main cloud, unlike the roll cloud. The underside is concave upward, turbulent, boiling, or wind-torn. Tornadoes rarely occur with the shelf cloud.
Cloud variety
A subdivision of cloud genera based upon transparency and the arrangement of cloud elemets. Cloud varieties are:
duplicatus (du) – more than one layer at different levels
intortus (in) – irregular or tangled
lacunosus (la) – thin cloud with regularly spaced holes, net-like
opacus (op) – completely masks sun or moon
perlucidus (pe) – broad patches with some (small) gaps allowing blue sky to be seen
radiatus (ra) – broad parallel bands convergind owing to perspective
translucidus (tr) – translucent enough to permit the sun or moon to be seen
undulatus (un) – sheets with parallel undulations
vertebratus (ve) – looking like ribs or bones
The standard abbreviations consist of the first two letters. None, one or more of the terms may be applied to describe an individual cloud type (genus).
Accessory clouds
picture An accessory cloud is a cloud accompanying or adjacent cloud mass to another cloud, generally smaller than the latter, and separated from its principal part, usually a major cloud genus (or type) or sometimes partially merged with it. A specific cloud may be accompanied by one or several accessory clouds. Accessory clouds are:
arcus (arc) – arch, shelf, roll or wall cloud
incus (inc) – anvil
mamma (mam) – pouches hanging from underneath main clouds
pannus (pan) – ragged shreds of cloud
pileus (pil) – cap cloud
praecipitatio (pra) – fall, precipitation reaching the surface, usually in the distance
tuba (tub) – funnel clouds
velum (vel) – thin layer of veil
virga (vir) – fallstreaks, trailing to the ground
and last but not least the banner cloud
El Nino
The term El Nino means ‘Christ Child’ and was first used by Peruvian fishermen in the late 1800’s to describe the warm current appearing off the western coast of Ecuador and Peru around Christmas time. Today El Nino describes the warm phase of a naturally ccurring sea surface temperature oscillation in the tropical Pacific Ocean. When this warming occurs the usual upwelling of cold, nutrient rich deep ocean water is significantly reduced. Sometimes an extremely warm event can develop that lasts for much longer time periods. In the 1990s, strong El Ninos developed in 1991 and lasted until 1995, and from fall 1997 to spring 1998. This oscillation is associated with the atmosphere, and thus the term ENSO � which incorporates the southern oscillation phenomenon – is commonly used.
So how can you determine if an El Nino event is occurring today? Certain changes typically occur to both the atmosphere and ocean during periods of El Nino and La Nina, and thus if factors such as wind velocities, sea surface temperatures, surface air pressure and sea level are monitored these changes can be detected. Here are some things you can focus on in order to determine whether an El Nino is currently occurring.
SST
Sea Surface Temperatures
During non-El Nino and non-La Nina conditions sea surface temperatures are approximately 6-8 degrees Celsius warmer in the western tropical Pacific than in the eastern tropical Pacific. These temperature disparities typically occur because the easterly trade winds that blow across the tropical Pacific move the warm surface water with them from east to west. Thus, you could look at SST data to determine whether an El Nino event is occurring at present, or not.
Trade Winds
During non-El Nino and non-La Nina conditions trade winds typically blow to the west across the tropical Pacific, but during an El Nino event the trade winds typically slacken or reverse. Thus, you could look at wind velocity and direction to determine whether an El Nino event is occurring at present, or not.
Other factors to consider when determining whether an El Nino event is occurring: during non-El Nino and non-La Nina conditions the sea level is typically 0.5m higher in the western tropical Pacific because the trade winds move water with them from east to west. This movement of water also causes the thermocline in the west to be deeper than in the east, and as result upwelling typically occurs in the eastern tropical Pacific. During an El Nino event the trade winds typically slacken or reverse as shown above and thus less water is moved from east to west, so SST, sea level and the thermocline all increase in the east.
The Southern Oscillation Index (SOI) can also be monitored and recorded, indicating when El Nino events are taking place. During an El Nino event the surface air pressure is typically higher in the western tropical Pacific, than in the eastern tropical Pacific. The (SOI) measures the monthly/seasonal fluctuations in surface air pressure differences at Tahiti and Darwin (Equation = Tahiti � Darwin), and thus the SOI usually has a negative value during an El Nino event.
Doppler radar
doppler radar The Doppler radar is a device that measures the Doppler shift in a radar beam reflected from an object’s motion towards or away from the radar aerial. This so-called ‘Doppler-effect’ is used in meteorological radars where the objects are water droplets on either side of a rotating mesocyclone, thunderstorm or tornado.
doppler radar Angular velocity can be calculated from the extent of the red shift on one side and blue shift on the other. This technology is used for the meteorological NEXRAD (Next Generation Radar) system to measure both, simple precipitation patterns and the severity of thunderstorms or the likelyhood of tornado development.
Funnel CLoud
People often use the terms tornado and funnel cloud interchangeably. There is however a distinct difference. A condensation funnel is a tornado, not a funnel cloud, if either a) it is in contact with the ground or b) a debris cloud or dust whirl is visible beneath it. Funnel clouds have no detectable debris or damage at ground level. The same is true for waterspouts. If there is a dark spot appearing on the sea surface underneath a condensation funnel, than it is a waterspout. If not, it’s a funnel cloud.
Earth’s Atmosphere
The Earth is surrounded by a blanket of air, which we call the atmosphere. The atmosphere has no precise upper limit, but for all practical purposes the absolute top can be regarded as being at about 200 km. However, from a scientific point of view the atmosphere reaches up to 600-700 km. Thus we are only able to see – and feel – what occurs fairly close to the ground. The atmospheric air has over large parts a fairly stable composition of roughly 70% nitrogene, 21% oxygene and a variety of trace gases.
Life on Earth is supported by the atmosphere. The atmosphere absorbs the energy from the Sun, recycles water and other chemicals, and works with the electrical and magnetic forces to provide a moderate climate. The atmosphere also protects us from high-energy radiation and the frigid vacuum of space.
The structure of the atmosphere
The envelope of gas surrounding the Earth changes from the ground up. Four distinct horizontal layers have been identified based on thermal and convective characteristics (temperature changes), chemical composition, movement, and density. From the surface of the Earth upwards the layers are:
(a) The troposphere, in which convection is often prominent and in which most significant weather occurs, where temperature generally declines with height. It is extending to the tropopause at a somewhat variable height, generally about 11 km over middle and higher latitudes and 18 km near the Equator. This layer is known as the lower atmosphere.
(b) The stratosphere, in which there is much less vertical motion, and which extends from the tropopause to about 50 km at the stratopaus e. The lowest region of this layer is usually isothermal, but the temperature then increases with height.
(c) The mesosphere, in which there is once again more convection, extending from the stratopause to a height of about 86-100 km at the mesopause. In this region, the temperatures again fall as low as -93°C as you increase in altitude. The chemicals are in an excited state, as they absorb energy from the Sun. The regions of the stratosphere and the mesosphere, along with the stratopause and mesopause, are called the middle atmosphere.
(d) The thermosphere, extending from the mesopause to the effective limit of the atmosphere, at about 200-600 km. Temperatures in this region can go as high as 1,727°C. Chemical reactions occur much faster here than on the surface of the Earth. This layer is known as the upper atmosphere.
(e) The region above 700 km, at which height atoms may begin to escape into space is known as the exosphere.
On the basis of chemical composition the atmosphere consists of only two layers, the homosphere (largely identical with the troposphere, stratosphere and mesosphere) in which the composition is essentially constant, an the overlying heterosphere.
Specific ionization and photochemical processes occur in the ionosphere(encompassing part of the upper mesosphere and thermosphere) and the chemosphere and ozonosphere (both part of the upper stratosphere).
Beaufort Scale
The Beaufort wind scale is a standard scale, running from force 0 for calm to force 12 hurricane and above for the description of wind speed. Each value represents a specific range and classification of wind speeds with accompanying descriptions of the effects on surface features. It was originally developed as a system for estimating wind strengths without the use of instruments.
It was introduced in 1806 by Admiral Sir Francis Beaufort (1774-1857) of the British navy to describe wind effects on a fully rigged man-of-war frigate of the period, and it was later modified to include descriptions of effects on land features as well. It is currently still in use for this same purpose as well as to tie together various components of weather (wind strength, sea state, observable effects) into a unified picture.

Thunderstorms
Thunderstorms are local storms accompanied by lightning and thunder and a variety of weather phenomena, such as heavy rain, hail or – in winter – snow, high winds and sudden temperature changes. Thunderstorms originate when intense heating causes a parcel of moist air to rise from the earth’s surface into upper levels of the atmosphere, a process called convection. Thunderstorms are therefore also known as convective storms.
At any given moment, it is estimated there are 2000 thunderstorms in progress around the world. They occur most frequently in the tropics but are also common in the mid-latitudes.
Thunderstorm ingredients:
Thunderstorms need an ample supply of moisture, preferably in the lower and mid-levels of the atmosphere, as they are mainly powered by latent heat released as water vapour condenses.
Thunderstorms need unstable air, a temperature profile with warm air near the ground and cold air aloft. When an air parcel is given an initial push upwards it will continue rising without additional force. Thus thunderstorms are more likely in the spring and summer than in the fall and winter. The sun warms the ground, which warms the air near the ground. In spring the air aloft retains its winter cold and thus will be more unstable than in the fall when the air aloft retains its summer warmth.
Thunderstorms need a source of lift. This can be (1) differential heating when air near the ground is warmer than in upper levels, (2) orographical effects when air has to rise to pass a mountain ridge, (3) frontal boundaries when air masses of a different temperature clash, (4) drylines when air masses with differing humidity but similar temperatures clash and (5) Land/Sea breezes. Thunderstorms can get started by even faint air boundaries and thus sometimes seem to pop up out of the blue sky.
Thunderstorms are often accompanied by severe weather and lightning is among the biggest weather killers. However, less then one percent of all thunderstorms produce hail bigger than the size of a golf ball and/or strong downburst winds. Only a small fraction of severe storms actually produce tornadoes or waterspouts.
No place in Europe is completely immune from the threats of thunderstorms. Severe weather can strike at any place, and at any time. Thunder and lightning occur simultaneously but thunder is heard later than lightning is seen, as light travels faster than sound. A good measure of distance from a storm is 1 mi (1.6 km) for every 5 seconds between flash and thunder.
Thunderstorm Probability
The Lifted Index is a measure of atmosphere’s stability (or instability) and Meteorologists use it to determine the thunderstorm potential. It doesn’t accurately predict the intensity of every single storm, but it is a useful tool to estimate the atmosphere’s potential to produce severe thunderstorms.
“Parcels” (or bubbles) of air start to rise on their own if they are warmer than the surrounding air. This process is called convection. Consider an air parcel as it begins to rise through the atmosphere after being heated by the sun and the warming ground. The Lifted Index is defined as a rising parcel’s temperature when it reaches the 500 millibars level (at about 5,500m or 18,000 feet asl), subtracted from the actual temperature of the environmental air at 500 millibars. If the Lifted Iindex is a large negative number, then the parcel will be much warmer than its surroundings, and will continue to rise. Thunderstorms are fueled by strong rising air, thus the Lifted Index is a good measurement of the atmosphere’s potential to produce severe thunderstorms.
For example, if the rising parcel has an temperature of -5°C when it reaches 500 millibars, but the actual temperature at 500 millibars is -11°C, then the lifted index is -6 Kelvin (or K) indicating the potential for strong thunderstorms. However, there are no specific threshold values that correlate lifted index to thunderstorm severity. In general a negative Lifted Index indicates an unstable atmosphere, so the larger the negative number, the more unstable the atmosphere is, the stronger a thunderstorm could be. Lifted index values rarely go below -7.
Now, find out about the convection and thunderstorm probablility across the British Isles yourself. Have a look at WeatherOnline’s new Lifted Index maps. The table above will help you to ‘read’ the map and to estimate the thunderstorm risk.
Important ! The Lifted Index is not a measured quantity, it is only a parameter that is theoretically derived. If the Lifted Index is favorable for severe storms but other conditions are not met, then no storms may form at all.

RANGE IN K COLOR AMOUNT OF INSTABILITY THUNDERSTORM PROBABILITY
more than 11 BLUE Extremely stable conditions Thunderstorms unlikely
8 to 11 LIGHT BLUE Very stable conditions Thunderstorms unlikely
4 to 7 GREEN Stable conditions Thunderstorms unlikely

Hi All,
Good Morning
partha sir,gud afternoon
good morning, what were you doing
GOOD AFTERNOON
good morning for tomorrow too early ……. 😆
just for fun . don’t be serious ….
rain possible by evening
strong westerly winds at ground levels today, but cloud cover has meant sun has not been able to come out on top today, I expect temp not to exceed 34.5 today.
Yes . Surely warmer than yesterday. At 11.30am today ,Nunga had recorded a high of 32 deg c and Meena surprisingly 31.6 deg c.
now reading please ?
any chance of rain today evening or night ?
I think it is highly impossible.
what do you think ?
City gets rains
Sudden showers lashed several parts of the city on Saturday, bringing down the day temperature.
Several areas, including Aminjikarai, Egmore, Chetpet, Velachery and Adyar experienced thundershowers from the afternoon. Areas in south Chennai experienced more rains.
The automatic rain gauges in Taramani and Anna University recorded nearly one cm of rainfall till the evening. While the weather observatory in Meenambakkam recorded 1 cm of rainfall, Nungambakkam had registered only a trace of rain till 5.30 p.m.
Officials of the meteorological department said Saturday’s rainfall was due to local convective activity followed by a prolonged period of intense heat and said rain or thundershowers would occur in some areas during the evening or night on Sunday as well.

Typhoon “WUTIP” centered 420 kilometers east of Vietnamese coast or latitude 16.7 degree North, longitude 111.6 degree East, is moving west at speed of 15 km/hr with sustained winds about 130 km/hr. It is expected to make landfall over Hue, Vietnam during 30 September. Thereafter, it will quickly decline before travelling to Nakhon Phanom, Thailand. Over the joint of both the North and Northeast, the storm is expected to decay, bringing more rain, isolated heavy rain and gust over the eastern and upper Northeast and the eastern North. Provinces include Nakhon Phanom, Mukdahan, Kalasin, Nong Khai, Sakon Nakhon, Udon Thani, Nong Bua Lamphu, Loei, Khon Kaen, Chaiyaphum, Phitsanulok and Phetchabun. Tomorrow afternoon, an outbreak of rain is expected in the eastern Northeast.
The stronger southwest monsoon affected torrential rain along the South west coast, as well as the stronger wind wave of the Andaman Sea and the upper Gulf of Thailand
Will it travel to bay???
No chance…
Nunga 33.4 Meena 32.6 Maximum readings recorded today.
Looks like sea breeze has just set in, a weak one though. Strange day weatherwise. So the september bang may not happen after all.
no storm forming yet hope for best
As of now no chance of storms forming
hope pypmksrikanth will heavy rain in Chennai soon
today blog so silent
Temp increasing in Bangalore, look at the pink sky

Srikanth wins week 2 competition
Not yet Partha, rains still could spoil it for me.
week 2 enters an interesting climax.
Srikanth has taken a 0.5 point lead over Rajkmr and only way he can lose it is if either Nunga or Meena receive 0.1 mm of rainfall.
Kea would it not be a case of rains has to happen at both Nunga and Meena, beacause if it is either one then I would be getting 5 points from the other for no rains. After a week and 28 predictions its as close as it could get.
The blog reflecting the radar, nothing in sight anywhere in 200 km radius. I am surprised how the radar is so empty all across the state.
