Statement 1 is correct: India experiences winter monsoon due to two reasons:
1) Influence of western disturbances in the North-West India.
2) Influence of permanent North-East trade winds in South-East India along the Coromandel Coast.
Statement 2 is also correct: Monsoons are seasonal winds that change their directions with respect to the temperature-pressure dynamics. They flow from high pressure or low temperature area to low pressure or high temperature area. In summers, the Asian landmass gets heated due to northward movement of the sun. Hence, the Indian subcontinent witnesses summer monsoons due to the change in pressure conditions in the subtropical landmass of Asia due to increase in temperature.
