NEM 2010 onset.

  1. North Easterly winds are 'RINISING' south eastern coast of India especially Tamilnadu. The SWM 2010 withdrawal is evident by widespread TS activity in Tamilnadu. Usually withdrawal will be pronounced in coastal areas, where as during this SWM 2010 withdrawal period interior and western parts of TN is experiencing more TS activity than the coastal area.
  2. My immediate boss pointed out a peculiar scenario in which it is noted that western Pacific High Pressure system located in China, is drifting towards WEST.
  3. This upper winds drag clouds along its path.
  4. Further the resultant reaction between receding westerlies and the meso scale incoming easterlies cause horizontal vortex to form and resulted in TS in interior to western parts of TN.
  5. It is interpreted from model OUTPUTS that in the entire troposphere, easterlies will be strengthening within next 36 hrs to proclaim the onset of NEM 2010.

    Hi Pradeep,
    Going by records of SWM, figures 20mm-50mm is not heavy. Especially this time desert areas received record 500mm in 24hours for 3-4 days.

    What does your prediction for NWM hold? Will it be 40% below normal due to El-Nino?

    Thanks

    Dear SSET,

    If the projected cyclone maintains its path towards central coastal TN. We will have banging start to NEM.

    Even last year we started like this and ended in positive.

    This year its the matter of depressions coming near TN coast.

    If we can get 3-4 we will get to normal rainfall.
