Describe the distribution of rainfall in different regions of India.
The distribution of rainfall is very uneven in India. It can be very well understood with examples of floods in Bihar, Orissa and West Bengal and droughts in the desert region of western India. The rainfall distribution varies widely from place to place and a number of factors are responsible for it. These include relief features and topography, direction of winds and latitudinal extent.
Based on the amount of rainfall received, places in India can be geographically divided into four regions:
1. Areas with very high rainfall: These places get an annual rainfall of more than 200 cm. These include the Western Ghats and northeastern states.
2. Areas with heavy rainfall: These places receive an annual rainfall of more than 100 cm but less than 200 cm. These include the eastern coast and the Himalayan regions.
3. Areas with moderate rainfall: These places receive an annual rainfall of more than 50 cm but less than 100 cm. These include parts of the Deccan Plateau and the Upper Gangetic Plains.
4. Areas with scanty rainfall: These places receive very less rainfall; the annual rainfall is usually less than 50 cm. These include the western parts of Rajasthan and the Leh region.
