According to Koppen's climatic classifications of India, Great Northern Plains are represented by
- A.Cwg Climate
- B.Aw Climate
- C.Amw Climate
- D.As Climate
Correct answer
Explanation
The correct answer is A, Cwg Climate. In Koppen's scheme for India, most of the Ganga plain falls in the Cwg type: a monsoon climate with a dry winter.
Koppen used letters for temperature and rainfall. C stands for a warm temperate climate whose coldest month is above minus 3°C but below 18°C; w means the winter is dry; g means the hottest month comes before the summer solstice and the monsoon, as May and June are hottest in the plains. The Cwg belt covers the Ganga plain, eastern Rajasthan, northern Madhya Pradesh and parts of the North East. Cool winters keep it out of the tropical A group.
Why the others are wrong: B, Aw, the tropical savanna type, covers most of the peninsular plateau south of the Tropic of Cancer. C, Amw, the monsoon type with a short dry season, is found on the west coast south of Goa. D, As, with a dry summer and winter rain, belongs to the Coromandel coast of Tamil Nadu.
Exam tip: Cwg for the Ganga plain, Amw for the Konkan-Malabar coast, As for the Coromandel coast.
