Monsoonal circulation is driven by: seasonal changes in insolation. differing heat capacities of the land and the ocean. upwelling in the coastal ocean. upwelling in the coastal ocean. Both A and B are correct.

Monsoon is the reversal in the direction of winds and the monsoon circulation consists of well defined seasonal changes. Monsoon is usually associated with the rainy phase. The global monsoon system mainly consists of western Africa and Australia and Asia monsoon. These seasonal winds below form the Arabian sea and the Bay of Bengal. The development of the monsoon has been linked to the uplifted Tibetan plateau. During the monsoon process, a large sea breeze occurs when the temperature on the land is warmer or cooler than the surrounding areas. This creates an imbalance of temperatures due to the land absorbs more heat than ocean areas. Due to which the temperature remains stable as water has a higher heat capacity and convection and conduction process. During the summer months, the land and ocean both receive the same amount of sunlight and the warm air above the land rises. The warm expands and low pressure develops, as the oceans have a low temperature than the land experience a high pressure this difference causes the sea breeze to blow from the land into inland and bing moisture. When the same wind flows back it's called a land breeze, this backward and forwards movement of wind on land creates rainfall over land surfaces. In the winter months, this cycle is reversed, the land cools faster than the oceans and high-pressure develop over the land surface while the oceans have low pressure. It cools and leads to rainfall over oceans. Similar rainfall is caused due to the upliftment from the mountains and surface heating. This type is known as Ororgrpahic precipitation.Thus it is clear that the rainfall or monsoon is created due to the differential heating of the land and oceans. The development of high and low pressure is attributed to the heating capacity of land and ocean mass. Arabian sea and the Bay of Bengal are the two branching systems that act as the dispersal of monsoon rains through the Indian landmass. The Bay of Bengal is called a northeastern monsoon.
