How is distribution of annual rainfall in related to the relief of the country?

Answer 1

The Western Ghats: places to the windward side of the Ghats, e.g., Mumbai, Goa, Mangalore, Kerala coasts, get heavy rain. Places on the leeward side like Pune, the Deccan plateau, Chennai, get less rain.

Garo-Khasi Hills: Cherrapunji, which is favourably situated in these hills, gets entrapped in the Bay of Bengal branch of the S.W. Monsoon and gets very heavy rain; Shillong, which lies on the leeward side of these Hills gets less rain.

Aravalli Hills: These hills run parallel to the Arabian Sea branch of the S.W. Monsoon and are not conducive to rain. Besides, the Bay of Bengal winds of the S.W. Monsoon coming from the east is blocked and hence Rajasthan, lying on the leeward side of these Hills, gets little rain. This is why Thar is a desert.

The Himalaya Mountains block the Bay of Bengal branch of the S.W. Monsoon from crossing the mountains. The places on the southern slopes of the Mountains get heavy rain.
