Why is there a decrease in rainfall?

As the moisture bearing winds of the Bay of Bengal branch of the south west monsoon move further and further inland, the moisture gradually decreases and results in low rainfall when moving westwards. Consequently, states like Gujarat and Rajasthan in western India get very little rainfall.

What are the factors that affect rainfall in India?

6. Factors influencing effective rainfall

Why does the rainfall decrease from east to west in India?

The Bay of Bengal branch of the monsoon winds moves towards northeast and return westwards covering the northern plains. While they move towards west their moisture contains tends to reduce with subsequent rains. Hence the rainfall decreases from east to west in northern India.

Why does the rainfall decrease from the east to the best in Northern India?

Rainfall decreases from the east to the west in Northern India because there is a decrease in the moisture content of the winds.

What affects the rainfall?

Factors controlling the distribution of rainfall over the earth’s surface are the belts of converging-ascending air flow (see doldrums; polar front), air temperature, moisture-bearing winds, ocean currents, distance inland from the coast, and mountain ranges.

What factors affect the rainfall?

Three factors that might influence the occurrence of precipitation are moisture supply, frontal position and atmospheric instability.

What are the causes of rainfall?

What causes rain? Clouds are made of water droplets. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain.
