Complete Concept Guide (100% Curriculum Coverage)
1. Factors Influencing India's Climate
India's climate is governed by Latitude (Tropic of Cancer splits the country), Altitude (cooler hill stations), Distance from Sea (coastal equable vs interior continental extremes), and Mountain Relief (Western Ghats blocking rain clouds).
2. Advancing and Retreating Monsoons
From June to September, the South-West Monsoon blows from the ocean, bringing over 75% of annual rainfall across two branches: Arabian Sea and Bay of Bengal. From October to November, winds reverse (Retreating Monsoon), blowing northeast across the Bay of Bengal to water Tamil Nadu.
3. The Rain-Shadow Phenomenon
When moisture-laden winds hit mountains, they rise, cool, and shed rain on the windward slope. The descending air on the leeward slope is dry and warm, creating a dry rain shadow (e.g. Pune receiving far less rain than Mumbai).

1
Why does Tamil Nadu receive most of its rain in winter?
Reveal Answer & Explanation
Answer: During the retreating monsoon, northeast winds cross the Bay of Bengal, absorb moisture, and strike the Tamil Nadu coast.
North-East winds crossing the Bay of Bengal.
2
What is a rain shadow? Give an Indian example.
Reveal Answer & Explanation
Answer: The dry leeward side of a mountain range; Pune lies in the rain shadow of the Western Ghats.
Leeward side sheltered from rain.
3
What are Western Disturbances?
Reveal Answer & Explanation
Answer: Mediterranean cyclonic storms that enter northwest India during winter, bringing vital rain for winter wheat crops.
Winter rains for Rabi crops.
4
Why is Mumbai's climate equable while Delhi's is extreme?
Reveal Answer & Explanation
Answer: Mumbai is on the coast where maritime breezes moderate temperatures; Delhi is far inland with continental extremes.
Distance from the sea (continentality).
5
What is 'October Heat'?
Reveal Answer & Explanation
Answer: The sultry, oppressive weather in October caused by clear skies, high temperature, and residual soil moisture.
High heat plus remaining moisture.
