The Continental Monsoon Trough is seen south of its mean normal position with a Low Pressure Area hooked to its eastern end. The aforementioned Low Pressure area is currently located near north coastal Andhra Pradesh and adjoining Odisha, which would result in heavy and widespread rainfall in parts of coastal Andhra, Odisha, Telangana and Chhattisgarh. The day time temperatures in the region would be a few degrees below normal owing to the convective cloud cover associated with Monsoon Trough. Meanwhile, the active west coast off-shore trough would result in widespread heavy rains along coastal Karnataka and Kerala. Rainfall activity would gradually increase over Tamil Nadu and Rayalaseema in the coming days.
Chennai would experience a cloudy day with the maximum day time temperature settling close to 35-36 C. There is a possibility of rains during the late hours.
Coimbatore to remain cloudy and overcast with a benign maximum day time temperature of 30-31 C. Chances of passing shower/drizzles.
Madurai will see a partly cloudy day and maximum day time temperature could be a warm 37-38 C.
Gud morning bloggers .from yesterday drizzles my area hardly recived 1 mm. Hope it gets more today as the lpa has moved north of us .;)
Good morning everyone.
Have a nice day.

“If you want light to come into your life, you need to stand where it is shining.” – Guy Finley
Part of south Chennai had trace to light rain last night.
Many parts of Chennai will have heavy rain from coming Sunday to Tuesday.Light rain is possible over some parts of city till Saturday.
Upper Air Circulation would bring heavy rain to many areas between South of Chennai to Kanyakumari, Southern Tamilnadu from 16th to 18th Aug.
Some parts of Interior Tamilnadu districts may also have medium to heavy rain between 16th to 18th Aug.
Is nunga included in your parts of chennai?
Isolated chances for isolated light rains as per his forecast!
wow..good news..
hope so it happens!!
Will I get answer in whatsapp
yes..all will tell yes!!
good morning everyone!!
expecting some rains today!!
We all expect rains daily
NAO likely to turn neutral by September, currently it is positive.
Normally negative NAO supports NEM to take to excess levels, however Neutral NAO might bring Normal rainfall in October. This NAO likely to become Negative by November. The pattern of NEM will be like Normal rainfall in October and November and good rainfall in December. NEM might end in Normal-Above Normal pattern in 2015.
So good 2nd half of NEM ahead of us.
perfect understanding Ehsan.
but i am worried bloggers may not be patient enough by seeing poor or near normal rainfall in October.
But normally December month action will be concerted to down south mostly
during abnormal climatic years this will not happen, NEM has got extended several times into Jan.
Above 12 lat?
yes jeetu,all will not cross 12N south tn will be benefitted much after dec.
Anything above DEC early week is not meant for n.tn
Kea good morning

Upper Air Waves becomes more pronounced as Rossby blocking.
The perfect matching of illustrated image and the current scenario.
When the polar vortex weakens, the polar jet stream slows and meanders in a form that allows the extension of low pressure lobes much farther to the south. These can become stationary for days and block the normal circulation of the atmosphere. The negative AO/NAO is associated with a slowed polar vortex and polar jet stream. When the jet stream slows, it meanders in a waveform pattern (Rossby waves).
The cold air extends upto Mid Latitudes and Warm Air raises up to sub tropics. This blocks the mid latitude free circulation at arctic circle, this bring changes in weather pattern in mid latitudes.
Picture attached.
After long time in my home town nellai, as usual it is hot with SWM winds making life comfortable
Fourth Day of Heavy Rains in Kerala.
Today Idukki – 71, Pambla 71 mm and Neeriyamangalam – 66mm
Positive IOD + ELNINO,
We never had an history that during ELNINO years, Positive IOD has not emerged in September. Hope the current 0.5 value has to sustain or increase in September too and get continued till October.
However the current forecast suggests that IOD likely to remain Neutral till September and become Positive in October and again Neutral in November.

Flash News,
Latest update on ELNINO forecast.
Strongest ELNINO to emerge in history. NINO values to touch 4C above normal by September end. No need to worry about IOD values from now on. ELNINO will take care of NEM. Strong NEM likely this time.
NINO 1+2 going to reach 4C above normal SST.
NINO 3 to touch 2C above normal.
Wow great news partner!
The above forecast is based on CFS and we all know that CFS is warm biased. Nino 3.4 will peak around 2.5C above normal, and not 4C.
CFS might be weak in predicting cyclones and rains, but they are the top most model in predicting waves and sst’s.
CFS is good in predicting waves but not in enso forecast. From past two years it was showing super el nino. Its a warm biased model and has done poorly in enso forecast.
All models in the world made that enso forecast in 2014 like cfs.
The point was the downwelling started in early part of 2014 and then there was counter upwelling happened in east pacific in May 2014. This cannot be forecasted by any models in the world. If there was no upwelling then for sure ELNINO would have emerged by that time.
No. POAMA was the only model which correctly predicted about 2014 event. When all the models were showing strong el nino beginning from June last year, it was the only model which correctly predicted about warm neutral conditions during JJA period in 2014.
when did they predict?
CFS predicted in April itself about the Neutral condition and ELNINO is doubtful. I remember these words from them.
I’m talking about 2014 event. During May last year all the models were showing strong el nino during JJA period except PAOMA. It was the only model which correctly predicted about warm neutral during JJA period 2014.
Friends, Can you let me know how come strongest Elnino willhave good NEM ..i am just trying to understand the correlation
Strong el nino cools down Western Pacific. This results in strong easterlies during NEM which gives good rainfall to TN.
actually i have lot of doubts…pls clarify
1. EL Nino year supposed to coold WP…lot of Typhoons this year.
2.Elnino is supposed to shift the trade wind pattern right..atleast it should take the momentum of rainfall bearing winds to EP right…
No, CFS is not warm biased

I think its too early to take a final call on NEM forecast. Lets wait till mid September.
But its a poll…It’s not too early, it’s the right time to think about NEM!
September would be a bit late to think about NEM

Oh
I’ve heard that NAMM is an average model
North American Multi Models Ensemble.
Is it reliable?
We will chk but most experts use this i ve ben following in twitter
September and October likely to be below normal
wat is tis? someone shd tell them we hav one rainy season with the name NEM during OND
Yes exactly
but what they hav forecasted is exact statstical precipitation of ELNINO .. see s.tn and srilanka not in damage path
Yes that’s a climatological probability only
recently few weeks back i had a small conversation with experts who r in US IRI climate forecast panel..he said most models gives weightage for tat climatology and later remote areas of sst forcing
Exactly
They don’t know what’s NEM! Lol
Has any model based out of aug predicted atleast normal nem for tn?? I ve posted NAMM and jamstec.. Kindly post others too for analysis..

Ukmet forecast for NEM 2015
Where?
Big time deficit in rainfall expected in August and September across the country.
The upper level wind anomaly suggests that the ACC over Northern part likely to remain weak. Also the mid level disturbance to weaken in next few days.
Temp difference not to higher in the coming days in each level of the atmosphere, the temp difference has to be more to get monsoonal rains to strengthen.
Again started another story
I thought it was raining everywhere
No no…
Mumbai has had many rain days this August, but none/not many greater than 10 mm.
Deficit as per today
Colaba – 299.9
Santa Cruz – 94.6
It’s very surprising. But it will do better from August last week onwards due to “stalled SWM dynamics close to central India”
mumbai certainly needs another 50 centimeters of rainfall for their comfortable storage in lakes. looks like difficult now, as already half of august gone. still 2 more weeks very crucial for them. if it does not rain properly, by end of this year mumbai would be on the same track of chennai and in fact usage wise three times more than chennai. it is really unfortunate. but weather gods always show mercy on mumbai, and this year may not be an exception. let us see.

I asked him to keep quiet for some time and come afresh
Ha..ha..
Good question
See the CFS long runs for September. Whole central, peninsular and west coast to be pounded with good spatial distribution of rainfall. NEM going to take onset on regular date only (around October 3rd week).
Ok, but I will take it with a pinch of salt

MISO wave not seen till sep 20th as per models outlook
everybody has to accept it
concerned indian, pilot, bug, what could be his next name
It is an easy guess “unstoppable”.
the problem is kea likes binamies like odm, bug
Why this year MISO taking shape exactly by 3rd week in every month in well disciplined manner??
The cool SST near Chile/Peru coast creating lot of upwelling only to suppress the present Elnino to reach “super” status.
No I don’t agree with this analysis because it’ll warm quickly in the coming days
The cool SST staying for long time. It must warm to stop upwelling mechanism for this Elnino to reach super category.
Wait and see
Rao,
Just few hours back I said to guest11k that we cannot trust CFS for its Cyclone and Precipitation forecast, but we can believe them in Tropical Waves forecast.
Now you are seeing the long run of CFS and saying that September rainfall will be above normal over entire country.
I have seen one reliable forecast for next 16 days time, this August is not going to recover, it will add up the deficits.
In September, as per my LRF, it should be deficit again.
Couple of times in June end and July mid we have seen some excess rainfall in some regions, that was due to Negative WP SST Anomaly, i have share the picture once again.
I tell you now, the deficit is for sure in August and September.
SWM 2015 will end in drought for sure.
SWM 2015 so far -9%, this will decrease in terms of percentage in Negative.
September can not be counted for whole country. Need to be excluded NW India (which already in excess) due to withdrawal of SWM. But CFS showing good rainfall with good spatial distribution for other parts of country. Let’s wait and see.
partha, june and july received good rains bcos of negative sst anomaly over pacific?? how far tis relation gets manifested in other elnino years?
will send you mail…
okay.. but try to share here too.let everyone learn
it is too big, lots of pics to be attached.
oh.. okay.
Partha, It’s very simple that still SWM runs on magic of MJO related MISO.
It can be another factor, but to be very precise, during ELNINO years either Positive IOD supports SWM, if it is absent to some extent WP Negative SST Anomaly will surely support.
As we are seeing the cyclogenesis forming over WP has become a villain nowadays to SWM, it has pulled down or weakened the precipitation.
But 1972, 1982 & 1987 also had +ve IOD, but ended with SWM deficits.
Partha, Relative cool SST at WP or Nino 4.0 is the typical Elnino style. So can you compare WP SST/Nino 4.0 SST vs SWM rainfall in 1957, 1965, 1972,1982, 1987, 1997 (all are strong Elnino years of the past century).
Can Hyd expect early winter from october….Badly missing cold wave here…Hoping good monsoon dynamics atleast in next lanina year..Iam ready to pick out my coats
For SWM to do its normal business, MJO must make regular rotations around all phases with amplitude just around 1. If MJO exhibiting any abnormal/irregular/strucked patterns, then SWM will get effected adversely. To know this compare 2005 MJO pattern vs 2014/2015.
Let us forget swm 2015….It did not make its presence well this time…Telangana may end with 50 percent deficit for sure..Just expecting one or 2 heavy spells for drinking water
Ready to enjoy winter if it comes soon by october
Given the situation, IOD has not been able to counter the effects of both El Nino and MJO. August will thus, witness below normal Monsoon conditions. Cumulative rainfall for August and September is forecast at 92% and 112% (error margin of +/-9%) of their monthly LPAs, respectively.
http://www.skymetweather.com/content/weather-news-and-analysis/southwest-monsoon-el-nino-and-mjo-rides-over-iod/
But all SWM deficit strong Elnino years also have +ve IOD. For example 1972, 1982 & 1987.
lol..utter blabber. what is countering what? first of all where was the iod to counter? when did they observe dipole like circulation?
rofl.. after challenging imd only they realize that monsoon is a very complex thing and tough to predict when they interacts with elnino.. what story is tis.? now atleast they came out of dream. skymet ,welcome to the world of METEOROLOGY after all self claimed success stories
Yes, lol
Dhawan b Pradeep 134
lead by 121 runs..
Partha, relative cool SST at WP or Nino 4.0 is the typical Elnino style. So can you compare WP SST/Nino 4.0 SST vs SWM rainfall in 1957, 1965, 1972,1982, 1987, 1997 (all are strong Elnino years of the past century).
Perfect cooling does not happen in WP, still the SST is 1C above normal in WP till date.
Normal means?
see NINO 4 region mentioned as 0.9C, in June and July it was more than 1C, this is what i said negative anomaly.
Means Relative trend in cooling
Ok buddy
Skymet not controlling themselves even after getting a hit in June and July.
The deficit in July was nearly -15%, but what skymet forecasted was normal to excess, if I am right they were saying 102%, July ended with 85%. In the beginning of July itself i said that they are predicting July rainfall based on MJO in the mid of the month. That MJO as forecasted by Kea bloggers, it went weaker one.
So far skymet has not learnt or observed the past 14 ELNINO years, this is why so many flaws in their forecast, at least by now they should press pause button and learn more and come back.
Kea forecast – August and September will be deficit. By numbers August will be more and September will be less. 2015 SWM is a drought year as per KEA and IMD.
September to be far below to August??
exactly…
i can challenge.
Sep will edge aug
Partha don’t challenge it and pray for more rain
Spot on
This is a technical blog no room for prayers n other supernatural powers…
Skymet going to go international now. They are tired of competing with IMD
the same thing you said in June and July too, now all india deficit stands at -15% as of 31st July.
he didn’t say anything about june & aug rains till now..he told about july end rainfalls ( along with pj) & now he says about sep rains..
I spoke about SWM-2015. I still have to practise to give monthly out put like our friends.
Sabash…. sariyana Potti……However god only will win
Spot on
Yes…convincing/thumping win
Only problem SWM-2015 keeping longer than normal gaps between 2 Rainey active intervals
Thats the difference between normal/excess and drought years no? Break periods observe very little rain.
But SWM-2015 break periods are entirely different from other break periods. In other deficit years there will be prolonged dry periods and with scanty rainfalls after SWM resumes its duty. But 2015 year SWM are bouncing back with heavy rains (instead of scanty rains of other Elnino deficit years) after break periods.
Swm Till 12th Aug all India % deviations frm normal
E,NE at -12%
Central -8%
South biggest surprise -20%
Nw +2%
will they be compensated in sep, when axis moves down to south?
No..tat would mean big floods to wipeout entire deficit which may look good on stats n paper but will cause even more calamity..
Huge deficit over West Coast, you are saying not bad??
If you compare the SST anomaly of 2015 with 1997, then you will know why SWM has good rainfall in June and July.
The value of SST anomaly if you see for June 1997, will match with July 2015, means the development of ELNINO was little late this year. This is why June and July deficit standing in single digit.
In August it will climb faster than 1997, the NINO regions will hit 2C by end of August for sure. This will overtake 1997 NINO values of August.
This is why i said that August and September will have huge deficits.
Partha, west coast will be pounded mercilessly before SWM exit from that region. Just wait and see.
Overall west coast will end in normal category.
ELNINO picked up late this time in 2015, atleast 1 month lag comparing to 1997. Now it will pick up faster, hence subsiding rainfall expected across.
But Elnino already reached peaking stage. Still it will pick up to detrack SWM further??
How many times u say the same u posted swm is over then again balti…jst stick to one in mind..
Rao,
The July deficit was not -5%, it was -16%.
Just check the link below of first week report in August.
Click to access weeklypress.pdf
Yes, but I understood as SWM cumulative RF at the end of July 31st as -15%. If we see only July then it’s -16%. But total including both June & July it’s -5%.
now it is at -9%
They are setting up a R&D centre in US to take on the rest
Anywhere in the world it is easy to forecast and predict, Except AB, BOB & Indian Ocean
SWM will withdrawn from 60% to 75% of our country on or before 10th Sept 2015….
Expecting Deficit to increase further . . .
then NEM on time?
Really??? If SWM withdrawing 75% of the country by September 10th, then why NEM going to take place around October 20th only?? Remaining 40 days what’s going to happen??
is there any chance of pre-nem cyclone?
Difficult to say
more Dull Days…. NEM expected to Sets in around 13th to 18th Oct 2015
Yes
how can you predict something which is 2 months away?
Whatever we are predicting above 2 months is called forecasting skills. . .
Agumbe deficit by 1500 mm
Lol…still no water in godavari and krishna….karnataka facing very severe drought in decades
Worst situation in godavari krishna and cauvery
UAC just gave 10 mm to hyd…pity
Can atleast NEM save south AP….or it is also going to fail???
Good BOB cyclone season ahead if IOD doesn’t increase above +1.0 during OND. Anything can happen.
Huge deficit over Kerala, KTK and Maharashtra till date.

@disqus_RhSGwm7xM9:disqus,
I agree with you on praying for rains instead of challenging the deficit.
However, i can do that outside blog, but here we are commenting based technical parameters, why should say it will rain normally during ELNINO year??
The fact is the Phenomenon, we cannot go ahead, even if i pray nothing going to change sir.
positive iod, you can visit SWM 2015 page and see the forecast given by me in June first week.
Then why same +ve IOD in strong Elnino years like 1972, 1982 & 1977 given deficit SWM
that is why i asked you to read the swm 2015 page, i gave why.
1997 we had Positive IOD in July, bought massive rainfall.
But why same massive +ve IOD in 1972, 1982 & 1987 (in June/July itself) comparable with 1997 resulted in deficit SWM in those years (contrary to 1997)?? IOD: http://www.jamstec.go.jp/frcgc/research/d1/iod/DATA/dmi_HadISST.txt
this is not politics boss, just comedy
Lol
Jupi expecting deficit SWM (that too chennai I think) for successful NEM according to NEM based on CONNEM. Is your theory completed or not? When we will receive first draft??
How was 2003 NEM in chennai
you really want to know?
Just reading about NEM…I saw TN was just 4 percent deficit in 2003 but chennai received only 310 mm
O -149
N – 85
D – 77
Deficit in Chennai, Normal in TN.
Very Very Poor NEM and SWM
Annual Rainfall Was Only 737.7 mm
NEM for T.N especially for Chennai has become like Sachin, like people eagerly waited for his 100th century, after his 99th, every year we wait for good nem, but it has other thing in mind it seems, again some models predicting poor nem this year also, but what will happen in real? fingers crossed.
No Worries… Our Super Experts are Confident on Good NEM – Jupi Anna And Partha sir…
Missing my college in Tirupati….As I shifted to hyd I can No more experience NEM except SWM…
But south west monsoon this time is very pathetic and miserable
same situation happening in NEM in chennai for the past 3 years…
i really liked your comment about chennai airport, it is really super
Lol… Thank You!!!
SWM in hyd is really very pathetic…
HYD usually gets 1000mm
this time till now only 280 mm. I saw hardly 2 day rain till now.SWM going to end…Even 500 mm is very difficult
W.pacific : One forecasting agency revised their earlier seasonal forecast of 7 super typhoons to 9 super typhoons in their update now ,making it 3rd highest ever..
there is a difference in which one emerging first, either ELNINO or Positive IOD, in 1972, 82 & 87 IOD emerged before SWM, may be the previous year also, hence it was not working out, in 1997 Positive IOD emerged strongly in July, hence SWM rainfall was excess across the country and below normal in Chennai.
Better 1987 to be excluded as Elnino continued from its previous year 1986. So 2015 exactly moving in 1987 style. So we will consider 1972 & 1982 vs 1997 (all 3 had similar timing of Elnino initiation except +ve IOD establishment).
Exactly 2015 so far in 1987 style, 1987 was fall ELNINO.
There are 2 terms in any weather phenomenon’s occurrence,
Increasing & Fall. 1987 was fall during SWM.
So from winter onwards Elnino start receding (means some parameters will weaken away from Elnino strength)?? for example SOI returned to neutral range during NEM season in 1987.
As per ECMWF monthly forecast, We will be having +NAO during NEM, and not -NAO which CFS is forecasting.
Also strong westerly phase of qbo during strong el ninos, favors +NAo, +Ao during OND period. So if this el nino strengthens above +2C anomaly then we can expect +NAO during NEM.
ECMWF agrees with above scenario. CFS going with -NAO.
+NAO means poor NEM??
There’s no clear relation between NAO and NEM.
But we discussed last year about research articles stating that -AO/-NAO to strengthen Siberian High (SH), which can enhance the NEM winds.
Yes, Negative NAO results in good NEM but there are few positive NAO years in which NEM was good. SO +NAO does not mean bad NEM.
JAMSTEC expects el nino to peak in September around +2.5C and then start decreasing whereas BOM, ECMWF, JMA expects it to peak in November.
When is this Elnino going to turn into Lanina..will it extend till 2016
No 2016 can be a strong La Nina
Don’t expect strong LA nina in 2016, when do you expect this elnino will start decreasing?
ohh ohhh then what will happen to 2016?
Will be better
2016 to be weak lanina followed by strong lanina in 2017 (just can comparable with 1997-99 episode). Or need to compare with 1987-89 episode.
By June 2016 it will turn neutral and by September into weak La nina or cool neutral stage.
La Nada?
1997 & 1965 saw the highest ever number of super typhoons. 11 super typhoons recorded both the year but the overall count was not impressive .. The year 1964 which is a lanina year seen with 39 storms tat includes 26 typhoons & 7 super typhoons.
1965 was strong el nino with neutral IOD.
So whatever it may be the index of other oceans, Pacific rides on Elnino.
there were around 20 bores in our area during last week of July. but no bore during aug, bcos all the biharis were sent back by the collector from avadi sekadu
Partha, +ve IOD emerged now and ER going to peak. So according to your analysis (just read SWM vs IOD and waves) will SWM will become active from coming week onwards??
Just touching the 0.5C mark will not say Positive IOD emergence, it has to sustain for some more days, i do not know how long, we need to wait and see for its sustenance.
In between what this +0.5 will do?? Will it sit ideally without influencing weather dynamics??
Ecmwf seasonal sep to dec show near to below normal precip for se india and above normal temps..
Rami,
I think we should not go by the values of IOD or ENSO, the arrival has different date. Check the following page.
Example – we say in 1982 Positive IOD arrived in Jan itself, but this article confirms the arrival in September and Peaked in November.
I think Jamstec is good agency. Why can’t we believe their indexes??
