  1. Kea I kind of disagree..

    I would say a pleasant winter…

    december was very cool take max temp into account consistently below 30 c and till now temp has just touched 30c which is very much acceptable…

    humidity way too low…

    except last week it was very dry…

    had an one day outing in vgp saturday not a drop of sweat

      • hardly minimum temp goes down like 5 , 6 times below 20 C…so it is really not that significant..
        if it stays pleasant i am happy…Max temp is the one really matters in chennai it does decide the uncomfortable factor…

        Swaeat is just begining to creep up…

        I could see mango flowers blooming in my house so indications are “summer Arrived”

  2. Heatwave Assessments

    Heatwave Situation for Saturday, Sunday, & Monday (3 days starting 7/02/2015)

    Low intensity heatwave conditions over most of WA extend into the southwest of the NT, northern SA, southwest Queensland, western NSW and also northeastern Victoria. Severe heatwave is present over the Interior and Kimberley districts of WA and also the northwest of SA. Some extreme heatwave conditions can be expected over the western parts of the Kimberly district.

    Heatwave Situation for Sunday, Monday, & Tuesday (3 days starting 8/02/2015)

    No major change to the areas of the low intensity heatwave. Severe heatwave conditions have extended over most of WA apart from the southwest.

  3. Well can i have the pictures from Kea meet..
    I missed the event ..

    Let us get together once in 3 months in a common place not a sports event though any general meeting will do…

    Strong Currents Over The Subcontinent During Feb And March Help Airlines Speed Up And Yet Save On Fuel

    Cruising at 35,000feet, if you find your plane unusually quiet, then in all probability you are being swept across the sky . Pilots call it a tailwind ­ a wind blowing in the same direction as a plane is flying ­ and airlines like them because it speeds up a flight without using much fuel.

    A British Airways Boeing 777-200 from New York to London once flew into a strong jet stream of 322kmph over the Atlantic and reached its destination in a record five hours, with the plane clocking a ground speed of 1,200km per hour. Experts regard the ex perience of the BA flight as extremely rare, but it is usual for aircraft to fly on a favourable wind of up to 160kmph.

    Pilots and experts say flights often experience strong tailwinds in Indian skies. This helps domestic flights save 15 to 20minutes, mostly when the route is from west to east. And incidentally , winter is the best time of the year to fly from Mumbai to Kolkata, Delhi, Lucknow; Dubai to Mumbai, Chennai and Bangalore; and Kochi to Bangalore, if you are looking to get there ahead of schedule.

    As the subcontinent is located above the equator and between two major tropical jet streams that course across the globe, winds are strong in winter and monsoon. “There are two major currents over the country .Westerly winds blow from west at around 111kmph at high altitudes, which help flights from February to March in the northern region, and then there is a tropical easterly from Malaysia across the peninsula,“ said former deputy director general of Indian meteorological department Y E A Raj.

    Flights from Mumbai to Kolkata and Delhi, Dubai to Mumbai and Chennai, and others that emerge from west and fly east usually shave off a few minutes on riding a tailwind. Planes flying Chennai to Delhi also sometimes run into a natural thrust beyond Nagpur. But return flights suffer because those fly into strong headwinds.

    “I have done Dubai to Chennai in three and a half hours instead of the more than four hours it usually takes because of a good tailwind. It gives the plane an additional push and means we don’t burn the entire fuel. A favourable wind is especially benefi cial for those flying transatlantic flights. An hour saved on a 10to 15-hour flight is a lot of money saved for the airlines,“ said a pilot. The tailwind is not even a safety hazard though it pushes the plane from behind, says air safety expert Captain Mohan Ranga nathan. “Tailwinds do not affect stability because it does not change the air speed ex perienced by the aircraft. It is the wind that gives the plane a push and takes it forward.“ Tailwinds form an important part of pre flight planning when wind patterns are studied. However, pilots do not go looking for a favourable wind while cruising because you have to stick to routes based on availabil ity of radar coverage. A Chennai-Port Blair flight cannot veer too far away from the air route just because a tailwind is blowing somewhere. Air traffic controllers need to see the plane too. “It is risky to try to cross a strong wind current. This is avoided be cause wind patterns on a route are studied before a flight plan is prepared,“ said a pilot.

    So the next time you get home early , re member it was just a favourable wind blow ing in your direction.

    February to April forecast

    For the February to April 2015 forecast period, low and near median streamflows are more likely (27 and 25 locations respectively), while high flows are forecast at six locations. Forecast skill scores for the February to April period are moderate or high for most locations. However, due to very low skill scores*, the forecast has not been issued at 16 locations.

    * We have changed how we categorise ‘skill’ to provide a fairer indication of our confidence in the forecast. ‘Skill’ is a relative measure to demonstrate whether the modelled forecast offers any improvement over using historical records alone.

    • January catchment conditions
      Low January streamflows were recorded at 37 locations in eastern Australia. Near median streamflows were recorded at 25 locations and high streamflows at 12 locations.

      January rainfall was below average for the Cape York Peninsula and this was reflected in low streamflows for the region. Rainfall was above average in central parts of Queensland and most of New South Wales and Victoria, however relatively dry soils in many of these areas meant this rainfall only resulted in low to median streamflows. Rainfall was 34% above average nationally and the Murray–Darling basin received 20% above average rainfall for January.

    • ENSO Tracker status: NEUTRAL
      The tropical Pacific Ocean has eased away from the borderline El Niño observed during late 2014. The Bureau’s ENSO Tracker status is now NEUTRAL. Climate models generally indicate that tropical Pacific Ocean sea surface temperatures are likely to remain within the neutral range for at least the next three months

      March to May 2015 streamflow forecasts are expected to be available by 10 March 2015.

  13. The Bureau of Meteorology’s Annual Climate Report 2014 is now available.

    Points of interest:

    2014 was Australia’s third-warmest year on record
    Australian mean rainfall was slightly above average
    Parts of the eastern States and Western Australia experienced below-average rainfall
    The year was marked by significant heatwaves, bushfires and storms.

    These reports provide a national overview of temperature, rainfall and significant weather and climate events of the past year.

  15. Complete “broom sweep” by AAP in delhi-2015 people’s verdict. Best of luck for the good governance & development. Hope something good out of this revolutionary change. Hope for the best…… 🙂

    • The change has to be available in Indian Democracy, more competences can erase the corruptions, this should pave the way for development, but party like AAP has to give faith to the people, it has to run the government and should not come to the streets and protest, also have to sustain for full 5 years, that is very very important.

      The same kind of change i want in Tamilnadu too, fed up of two regional parties keep on repeating and nothing done by them for development.

    • the real litmus test starts for them from now, they can’t run the show by just agitating, and doing dramas like they did in their short stint last time.

  16. Internet sites are not withstanding the heavy-rush. Most of the sites are not opening/showing out of service/unavailable service. This clearly indicates whole India is watching important AAP-Delhi election results……

  17. interesting facts about February rainfall over TN

    Though Feb is not a rainy month for tn but the interannual variation in rainfall during the month of feb makes a big extensive impact to farmers community by damaging the crops &other yield.. looking into the rainfall trend ,majority of years where February rainfall was absolutely nil over TN and at the same time there are years where it was exceptionally above normal.. 1984 february rainfall was 186mm. rainfall chances gets enhanced when a synoptic disturbances prevails in s.bay.

    again in the year 2000 feb rain was 7cm & 8cm in 2002 february .. During 2002 feb ,tn received 8cm of rainfall ,chidambaram recorded 25cm of rainfall on 3rd feb and kaatumannarkoil (cdl district) recorded 37cm of cumulative rainfall from 2nd to 4th feb.

    again 2008,2012,2013 were of similar kind rainfall happened either in feb or early march.. off season rainfall may be related to remote area of sea surface temp rise, synoptic activity in s.bay and also due to enso impact. interestingly
    imd experts says that rainfall activity in February is mostly occurring in the years in which earlier
    post monsoon season cyclone activity is less..

  18. Selvan,

    Yes, Feb is month that inter annual variability begins, and peaks by end of March and in April perfect summer sets in to
    heat the land and cool the ocean.

    This inter annual variability period has to be normal, it should be drier, so then we will get normal monsoonal rains during SWM and NEM times. This period is very important to have dry days instead of precipitation. If we have precipitation then
    it means that the variability is getting delayed, this will in turn delay the onset of SWM rains.

    Yesterday I saw the report in CPC, that 850HPA vector winds were from east to west over Indian Ocean since the beginning of NEM, now slowly that is weakening, it means that the inter annual variability is happening on time. The 200 HPA west-east wind is slowly starting to weaken over Indian Ocean, it is weak at the moment but the direction is consistent, this is very important for the onset of SWM on time. Hoping to see SWM on time, but still we have to wait till April mid to get clear picture.

    Also MJO is expected to hit Phase 2 in next 10-15 days time, this should bring more moisture to SW Indian Ocean and there may be a system formation, hence this should dry up the North Indian Ocean above equator. Once the northern part dries up the heating of land will begin, so we can expect increase in day temp by first or second week of March over sub continent.

    • hi partha,. hope u r fine. yes its always good to follow the reports from experts..and i dont understand the lines where u hav tried to point out 200hpa winds . 200hpa winds will be westerly from mid oct-mid april or early may.. and it will turn easterly only after swm sets in and we often call it as tropical easterly jets

  19. Unseasonal Typhoon in northwest Pacific Ocean
    This past week saw a strong burst of westerly winds near the equator in the west Pacific Ocean and the development of an unseasonal typhoon in the northwest Pacific. Typhoon Higos is currently located several hundred kilometres to the west of Guam and is not expected to impact on land.

    The recent activity over the northwest Pacific Ocean is unlikely to have been associated with the Madden–Julian Oscillation (MJO). Models suggest that the MJO will not be a strong influence on tropical weather for most of this coming week. Beyond this week, MJO forecasts show a large spread of possible outcomes. Without the influence of large-scale drivers such as the MJO, weather across the tropics will be influenced by short-term weather fluctuations including the strength and position of monsoon troughs and tropical lows. There is some indication that there may be an increase in tropical activity to the north of Australia over the coming week.

  20. Return of the North Australian Monsoon
    Weather models suggest a potential reformation of the monsoon trough near Australia’s north coast from early next week. An active monsoon brings with it an inherent risk of tropical cyclone development across the Australian Region.

    Northern Australia has been in monsoon break conditions for several weeks. Like most monsoon breaks, this past week included isolated thunderstorms mostly confined to northern coastal regions. However, unlike other break conditions, this past week included a few days across Australia’s Top End and Kimberley regions where dew-point temperatures dropped below 10 °C and some overnight temperatures dropped below 20 °C, which is unseasonably cool for overnight temperatures.

  21. El Niño–Southern Oscillation: neutral
    Ocean temperatures in the central equatorial Pacific Ocean, although warmer than the long term mean, have returned to neutral levels. The latest weekly sea surface temperature anomaly across the NINO3.4 region (which spans the warm waters in the west and the average waters in the central Pacific) is +0.5 °C. The latest 30-day Southern Oscillation Index to 8 February −8.4.

  22. LOW’s to LOW..

    Activity of Low Pressure will reduce and completely vanish in next 10 days time in SE Bay of Bengal and North Indian Ocean basins.

    MJO is expected to emerge in Phase 2 in next 10-14 days time, it will strengthen moisture in SW Indian Ocean hence northern part of Indian Ocean will become dry, also the 850 HPA winds are slowly weakening and losing the pace over North Indian Ocean region, this will give up any formations like LOW, once the 850 HPA winds from east weakens completely we shall see the start of summer, hope the temp to reach beyond 33C in Chennai from first or second week of March.

  24. The International Cricket Council will crack down on excessive sledging between players at the World Cup, saying first offenders can expect heavier fines while repeat offenders face suspension from matches.

    ICC chief executive David Richardson also said players with already poor records of on-field behaviour could face immediate match bans if found guilty of a single breach of the ICC’s code of conduct during the Feb. 14 – March 29 tournament.

  25. “We don’t necessarily want to follow the way that football goes. A lot of these decisions are taken after a measured response by match officials reviewing footage of the match afterwards.
    “That obviously cannot happen when you are brandishing a red or a yellow card on the spur of the moment.”

    ICC Chief Executive
