TROPICAL ACTIVITY UPDATE
Monsoon has completely withdrawn from the sindh province. Now the tropical activity season is ongoing. Tropical cyclones develop during pre monsoon and post monsoon when monsoon trough brings good moisture at low and mid tropspheric levels and also provide cluster of thunderstorms.
If other factors like sst (sea surface temperature) is high (above 27 C) and low windshear is available tropical cyclones develop and affect the coastal parts.
TROPICAL ACTIVITY UPDATE
SEA SURFACE TEMPERATURE;-Sea surface temperature is above 26C which is favourable for tropical activity.
MOISTURE AT LOW LEVEL AND MID TROPOSPHERE LEVEL;-
There is good amount of moisture in central arabian sea at low level but less moisture available in north and south arabian sea.Although there is more need of moisture at low level.
Good moisture available in east arabian sea at mid troposphere levels while negligible amount of moisture available in north arabian sea at mid troposphere level, which is unfavourable for tropical activity in arabian sea.
VERTICAL WINDSHEAR
This is the main factor for strengthening and weakening of a tropical cyclone.
Low windshear available in north arabian sea .However high windshear present in south arabian sea.
CONCLUSION
To conclude,no any cyclonic activity possible during next 8 to 10 days.After 8 to 10 days cyclonic activities possible in arabian sea.
If other factors like sst (sea surface temperature) is high (above 27 C) and low windshear is available tropical cyclones develop and affect the coastal parts.
