There are three types of rainfall:
Low rainfall (Less than 50 cm.)
Average rainfall (Between 50 to 250 cm.)
High rainfall (More than 250 cm.)
- Parts of the western coast and northern India received over about 400 cm of rainfall annually.
- It is less than 60cm in western Rajasthan and adjoining parts of Gujarat, Haryana and Punjab.
- Rainfall is equally low in the interior of Deccan plateau, and east of the Sahyadris.
- The rest of the country receives moderate rainfall. Snowfall is restricted to the Himalayan region.
- Because of the nature of monsoons, the annual rainfall is highly variable from year to year.
- Variability is high in the regions of low rainfall such as parts of Rajasthan, Gujarat and leeward (rain shadow area) side of the Western Ghats.
- While the areas of high rainfall are responsible to be affected by the floods and the areas of low rainfall are drought- prone.
