According to Koppen's climatic classifications, the Great Northern Plains of India have which one of the following climates ?
- A.Aw climate
- B.Cwg climate
- C.Amw climate
- D.Dfc climate
Correct answer
Explanation
The correct answer is B, Cwg climate. Koppen placed the Ganga plain of northern India under Cwg, a monsoon type with dry winters.
In Koppen's scheme, C stands for warm temperate climates whose coldest month stays above freezing, w means a dry winter season, and g means the hottest month comes before the summer solstice and the monsoon rains. This matches the Great Northern Plains, where May and early June are the hottest months, the rain comes with the south-west monsoon and winters are cool and largely dry. The Cwg type also covers eastern Rajasthan, northern Madhya Pradesh and much of north-east India.
A is wrong because Aw, the tropical savanna type, covers most of the peninsular plateau south of the Tropic of Cancer.
C is wrong because Amw, the monsoon type with a short dry season, is found on India's west coast south of Goa.
D is wrong because Dfc, a cold humid climate with short summers, is found in Arunachal Pradesh.
Exam tip: Koppen in India: Amw west coast, As Coromandel coast, Aw peninsula, BWhw Thar desert, Cwg Ganga plain, Dfc Arunachal, E Ladakh.
