The SWM winds have penetrated upto 100 Deg East IN LOWER LATITUDES. That to the vertical depth of westerly is APPROXIMATELY up to one km amsl. This weak westerlies make cycir-upper air circulation-[just like monsoon depression] and as a result (of Yesterday's cycir) it was cloudy over North Chennai [of course with light rain] and south CAP un to Machilipattinam. This will further move northerly and give lesser rain.
Even the 200 hPa wind is weak NEly. The 100 hPa wind at Chennai [i.e 13 Deg N] is also Easterly with strength 36knots. The SWM penetration aloft [~1.5km amsl] is producing weather in Bay and SE Indian coast.
Similarly the weak UAC in AS may pull SWly winds to AS.
