Question

Give five reasons for the uneven distribution of rainfall in India.

Answer 1

Hint: Rainfall in India is uneven, with some areas receiving a lot of rain and others receiving very little. Rainfall distribution can be divided into four categories:
- There is heavy rainfall in some areas.
- There is low rainfall in some areas.
- Rainfall is moderate in some areas.
- Rainfall is inadequate in some areas.

Complete answer:
The distribution of rainfall is uneven in India due to the following reasons:

Relief: The Western Ghats get a lot of moisture. As the Arabian sea branch of the South West monsoon strikes the Western Ghats, moisture-laden winds trigger very strong rainfall. Because of its relief, Mawsynram receives more rain. The Bay of Bengal part of the South-West monsoon brings rain.

Distance from the Sea: Areas along the coast get more rainfall as compared to those areas which further away from the sea.

Wind Direction: Due to the Arabian Sea Branch blowing parallel to the Aravalli Hills, Rajasthan receives scanty rainfall.

Inter-Topical Convergence Zone (ITCZ): During the monsoon season, it is also known as the monsoon trough. The trough and its axis continue to troll northward or southward, determining the rainfall distribution.

Disturbances caused by cyclones: Cyclonic depressions that arise over the Andaman Sea and usually cross India's eastern coasts cause heavy and widespread rain in the Godavari, Krishna, and Kaveri deltas, as well as the coasts of Odisha and West Bengal.

Note: The belts of converging-ascending air flow, air temperature, moisture-bearing winds, ocean waves, distance inland from the coast, and mountain ranges are all factors that influence the distribution of rainfall over the earth's surface.
