  1. “Hopefully we could get a week or two of good sunshine, which is beneficial for a good NEM.”

    Hehe..a day of sunshine will bring us thundertorms in this wonderful month ๐Ÿ™‚

  2. “”ok u are tellin total crap.. every station is uniqueโ€ฆ otherwise there wouldnt be 50cm gap between colaba and santa cruz annd 10 cm gap between chennai chennai AP.. try to appreciate the uniqueness of a station.””

    What crap are u speaking…the 1958-2009 averages for september over the lakes(red hilss,cholavram n poondi) is 13.7cm …in 2005 they have got 21cm which is excess…wat ur saying is NEM is dependant only one an individual station nungambakkam ..n it is totally independant on the others..so according to ur wonderful statistical co-relation..poondi,cholavaram n red hills shud have got deficient NEM 2005 ๐Ÿ™‚ ..while only nungambakkam shud get excess NEM..wat a co – relation ๐Ÿ™‚ ๐Ÿ˜›

  3. tropical storm karl is expected to become a hurricane from depression just by travelling some 200 kms ..now that is called explosive intensification
    thanks to very low shear and wram waters

  4. Karthik u dont understand anything.. pray for a dry september second half ( which usually is ๐Ÿ˜› ๐Ÿ˜› as august leaves its legacy to early september ๐Ÿ˜› ๐Ÿ˜› ๐Ÿ˜› ).. anyways bad chennai sept is good for NEM ๐Ÿ˜€

    see logically its simple.. if it rains in chennai city or dgp office (which are close to sea).. it means it can rain in the open seas and if its a stronger storm it can take more into the seas… therby bringing down SST which is indeed bad for the budding NEM…

    Lakes dont come into picture becos they are little far off from seas they themself being water bodies can have influence on local weather (refer internet).. so lakes cant be taken into account

  5. omg..KN ..lolzz…lakes affect local weather system s…but it shud be as big as the seas like the ones we see in america n central asia..not the that lakes we cannot even find in a district map ๐Ÿ˜› ..n usually its the second part of september thats the rainiest(after 15 september)…(refer IMD daily mean rainfall for TN) .august leaves a bad start to september..stop talking like fool once again..if ur gonne sy cholavaram is as big as the HOMES of america then seriously nobody can tell u anything ..so stop talking like a fool..n pls dont put any wrong info in this blog again…many ppl are followin it ๐Ÿ˜ก ..the peak sept rainfall is aorund sep 19-20 n 25-26 ..

  6. n that salem gets 65cm in NEM ๐Ÿ˜› ๐Ÿ˜‰ …btw november is only for coastal TN ..interior Tn is dry..n vellore’s september is wetter than november ๐Ÿ˜‰

  7. No East india and south peninsular india.Southern TN, Interior TN and adjoining kerala will have some heavy rains. Coastal areas in TN would have light to moderate rains during the same period. No more rains in west and north..Espcially no more mumbai rains :). I am referring to COLA predictions http://www.monsoondata.org/wx/prec.html

  10. jon…its jus now radar updated with batterin storms…b4 that its that streak we always see from pamban n over that region

  11. Many people have said august i dont think it is august which dominates swm for chennai..it is the month of september. what do you think?

  12. Most of the widesread rainfall occurs during late september .. The average precipitation for entire chennai is max in september than august due to widespread preciptation caused due to lpars, formed due to weaker swm monsoon winds during that period …August tops only for the most rainfall days in swm , it does not top for the widespread precipitation for the whole city.

  13. @Vinodh

    yes, according to 100 year data given by imd for chennai AP, August is the rainiest swm month…

    but in our recent times, unfortunately, especially last 10 years september has dominated…

    but in 1990-2000 also august only got more than september… for last ten years september doing suprisssssssssingly good…

    Hope it changes this year ๐Ÿ™‚

  14. @Vinodh but dont get illusion that september is the rainiest SWM month .. its only becos of recent years..

    we have 2 official (unlike somebody who s biased towards sept and says peak is on sept 19-20) statistics 1901-2000 chennai AP, 1950-1980 for Chennai city all pointing clearly that august is the best month for swm…

    Accu weather records say september is better(with recent data) but just marginally but number of rainy days is more in august ๐Ÿ™‚

  15. A note on september…

    September is a good month for leeward side of the ghats except coastal TN.

    Its the second rainiest month for many places in TN… like vellore, tiruchi etc

    Its not so good for coimbatore, mysore etc {most closest to ghats}

    It is also the rainiest month of bangalore… so Bangalore celebrates september ๐Ÿ™‚

  16. 1990-2010…august was very bad for nungambamkkam….september was roclking ๐Ÿ˜› ..i think some ppl ere observed from chintadripet

  17. “”but dont get illusion that september is the rainiest SWM month .. its only becos of recent years..””

    it is shud be coorectly put this way..many ppl luk at taht 1950-80 year data and get illusioned

  18. At leats soem ppl ere were sayin Ausgust was the rainiest swm month for the entire NORTH tn….now they have rolled back on their statement to chennai..n soon thtas also gonna change ๐Ÿ˜› ๐Ÿ™‚

  19. Haha…who have to still rolll back on ur statement

    “September is a good month for leeward side of the ghats except coastal TN.”

    From that 1950-80 data itself september is the rianiest SWM month for puducherry…so u hae to say…september is the rainiest SWM month for Tn…except north coastal TN ๐Ÿ˜›

  20. 1965-2008 averages over the lakes
    ——————————————

    August – 13.2cm
    September -13.7cm

    1901-2000 average over minambakkam
    ———————————————–

    August – 13.9cm
    September – 13.3cm

  21. @Vijays plzz say mjo dry phase… from 3rd week of october if mjo wet starts, it ll be awesome ๐Ÿ™‚

    but IRI results are disappointing looks lik that research paper which did correlation analysis with excess SWM and deficient NEM is right ๐Ÿ˜ฆ

  22. remember some ppl were saying july-august rocks like anything over vellore… how bad they had to roll back on their statement ๐Ÿ˜› ๐Ÿ˜ฆ

  23. South west monsoon 2010 rainfall over vellore district
    ———————————————————

    Vellore – 48.0cm
    Tirupattur – 47.6cm
    Melalathur -28cm
    Gudiyatham – 23cm
    Alangayam – 23cm
    Vaniyambadi – 20cm
    Ambur – 11cm

  24. Between 1981 and 2006, average annual rainfall in Chennai was 1,549.9 mm, far more than Bangaloreโ€™s 877.8 mm, Hyderabadโ€™s 821.7 mm and Delhiโ€™s 755.4 mm, according to data compiled by the Centre for Science and Environment.

  25. Chennai receives more rainfall than most large cities but has had to rough out several years of drought (thereโ€™s less of a scarcity now after the city administration enlisted new sources for drinking water). ๐Ÿ™‚

  26. Bangalore has had no problem wrt water or temperature or number of rainy days… its better than chennai in these parameters..

    but power cuts , cost of living & safety… oofff

  27. the problem with chennai is different… 120cm is definitely not enough… the other cities dont manage water problems thru rainfall alone…

    bangalore – kaveri (w ghats)

    Mumbai- a whopping 250cm rainfall and the lakes & dams(w ghats) !!

    Pune – dams (w ghats)

    Delhi – yamuna (himalayas)

    kolkata – hoogly ( himalayas)

    hyderabad – manjira river (w ghats)

    Chennai has been let out ๐Ÿ˜ฆ now dats the problem… we have no support of the ghats where it rains the most ๐Ÿ˜ฆ

    ironically, these days we receive indirect support from the ghats though ๐Ÿ™‚

    a) Veeranam lake – (water fed by kollidam, a branch of kaveri)

    b) Krishna river from the ghats

    conclusion: 120cm and 4 or 5 lakes not sufficient to support a mega metropolis of the size of 7.8 million

  28. @ KN

    Last 30 years chennai average is nearly 160cm with that if we are getting water scarcity then there is some problem in storing excess water.

    In fact we have so many lakes around us and still we are not utilizing and maintaining them properly.

  29. guys finally……………………withdrawal likely in nw india and central india during second week (25 to 01)!!!!!!!!!!!!!!!!!!!! ๐Ÿ™‚ according to press release from imd………… ๐Ÿ˜Ž

  30. i said eastern vellore which actually did do well(including k puram & vellore)

    Definitely not…eastern vellore district,likes of walajapet/ranipet, shud get less than vellore in all four months….btw this year walahjapet from IMD reports–

    Jan-may = 0cm
    June = 4cm
    July = 5cm
    August = 0cm ๐Ÿ™‚
    September = 4cm till now

    Year total = 13cm ๐Ÿ˜ฎ

  31. eastern vellore district is too far for Pre-monsoon….its is just in western kanchi district taht many tstorms form ..n the storms that give vellore rain gives much less rainfall der… ๐Ÿ˜ฆ

  32. poondi very close to NNW of tiruvallur…thats why every year it is among the lowest rainfall regions in that chennai lake data…and cholvaram is a lil north of ambattur n ponneri slitely to the NNE of cholavaram ..very close to te sea..so NEM also will be high over der

  33. โ€but dont get illusion that september is the rainiest SWM month .. its only becos of recent years..โ€”

    it is shud be coorectly put this way..many ppl luk at taht 1950-80 year data and get illusioned

    KR you are right we cannot trust data from 1950-80 as they are highly inaccurate..Karthik narayanan is illusionised by these old unreliable data ๐Ÿ™‚

  34. This september wont be that good because of late withdrawal..september will be at its best only if swm remains weak .. september rains cannot be called SWM rains neither NEM..
