Question

which are called south west monsoon winds​

Answer 1

On the other hand, the water surface of Indian ocean remains cooler and the pressure gradient is towards the heated interior. Trade winds are substituted by monsoon winds blowing from south-west. As the wind blows from water to land, it is moist and brings lots of rain. The wind is known as South-West Monsoon Wind.

IT has generally been held that the south-west monsoon owes its origin to the great difference of temperature which exists during the summer months between the heated land surface of India and the surrounding oceans, the general idea being that the warm air over the land rises, and damp air from the sea flows into.
