The correct answer is C) Southwest monsoon.
The southwest monsoon is a seasonal wind that blows from the southwest towards the northeast across the Indian subcontinent from June to September. It is caused by the difference in temperature between the land and the ocean. The land heats up faster than the ocean in the summer, causing the air to rise. This creates an area of low pressure over the land. The air from the ocean, which is cooler and at higher pressure, then flows in to fill this low pressure area. This is the southwest monsoon.
The southwest monsoon is a very important part of the Indian climate. It brings much-needed rain to the region, which helps to support agriculture and other industries. It also helps to regulate the temperature of the land.
The northeast monsoon is a seasonal wind that blows from the northeast towards the southwest across the Indian subcontinent from October to December. It is caused by the difference in temperature between the land and the ocean. The land cools down faster than the ocean in the winter, causing the air to sink. This creates an area of high pressure over the land. The air from the ocean, which is warmer and at lower pressure, then flows in to fill this high pressure area. This is the northeast monsoon.
The northeast monsoon is not as important as the southwest monsoon. It brings less rain to the region and does not have as much of an impact on the climate.
The retreating monsoon is the period of time after the southwest monsoon has ended and before the northeast monsoon has begun. It is a time of transition, when the weather is often unsettled. The retreating monsoon can bring heavy rains, but it can also be dry.
The winter monsoon is a seasonal wind that blows from the northeast towards the southwest across the Indian subcontinent from December to February. It is caused by the difference in temperature between the land and the ocean. The land cools down faster than the ocean in the winter, causing the air to sink. This creates an area of high pressure over the land. The air from the ocean, which is warmer and at lower pressure, then flows in to fill this high pressure area. This is the winter monsoon.
The winter monsoon is not as important as the southwest monsoon. It brings less rain to the region and does not have as much of an impact on the climate.
