| Abstract: | Area average rainfall of southern peninsular
India
is calculated for northeast monsoon season from daily gridded data. Years of
strong and weak northeast monsoon were identified. Sea level pressure (SLP),
sea surface temperature (SST), and 850 h Pa zonal wind are analyzed for years
of strong and weak northeast monsoon rainfall. Difference between years of
strong and weak rainfall of northeast monsoon high pressure anomaly over west
pacific region near Philippines, low pressure over west Indian Ocean including
Arabian sea, high SST anomaly over equatorial Pacific and Bay of Bengal. Among
these the Sea level Pressure difference (SPD) between west pacific and west
Indian ocean plays the key role in determining the strength of northeast
monsoon rainfall over southern peninsular India. |
