The rainfall decreases from the east to the west in northern India due to a decrease in the moisture content of the winds. The moisture-bearing winds of the Bay of Bengal branch of the southwest monsoon move towards the west, and as they move further, the moisture content in the winds gradually decreases, resulting in low rainfall when moving westwards. This phenomenon is primarily observed in states like Gujarat and Rajasthan in western India, which receive very little rainfall.

There are several reasons for this decrease in rainfall from the east to the west in northern India:

  • Reduction in moisture content: As the moisture-bearing winds of the Bay of Bengal branch of the southwest monsoon move towards the west, the moisture content in the winds gradually decreases, leading to low rainfall when moving westwards.
  • Intensification of low-pressure areas: There is an intensification of low-pressure areas as the moisture-bearing winds move towards the west, which further contributes to the decrease in rainfall.
  • Geographical factors: The unique geographical features of India, such as its location between the Tropic of Cancer and the Indian Ocean to the south, as well as the presence of the Himalayan mountain range to the north, also play a role in the decrease in rainfall from the east to the west in northern India.

In summary, the rainfall decreases from the east to the west in northern India due to a decrease in the moisture content of the winds, the intensification of low-pressure areas, and geographical factors. These factors combine to create the seasonal wind patterns and rainfall distribution that are characteristic of the monsoon climate in India.
