Though there is no single theory which can explain the origin of south west monsoon, however it is believed that the main mechanism is the differential heating of land and sea during: (1) Winter months (2) Summer months (3) Cyclonic storms (4) South-west trade wind flow

1 Answer

Answer :

(2) Summer months Explanation: According to the thermal theory, during the hot subtropical summers, the massive landmass of the Indian Peninsula heats up at a different rate than the surrounding seas, resulting in a pressure gradient from south to north. This causes the flow of moisture-laden winds from sea to land. On reaching land, these winds rise because of the geographical relief, cooling adiabatically and leading to Orographic rains, better known as the southwest monsoon.
