In Koppen's classification of Indian climates, the code BWhw, the hot desert type, is given to
- A.Eastern Rajasthan
- B.Extreme western Rajasthan
- C.Southern Punjab
- D.North-western Gujarat
Correct answer
Explanation
The correct answer is B, extreme western Rajasthan. The capital B marks a dry climate, the capital W marks the arid or desert subdivision, h marks a hot climate and the last w marks a dry winter, so the whole code describes the heart of the Thar, the driest part of the country. Option A is wrong because eastern Rajasthan receives enough summer rain to fall under Cwg, the monsoon type with dry winters, along with the Ganga plain. Option C is wrong because southern Punjab belongs to the less dry steppe type BShw rather than the full desert. Option D is wrong for the same reason: north-western Gujarat is shown as BShw, the semi-arid steppe. The single letter that separates the two dry codes is S for steppe against W for desert, and that is where most candidates lose the mark.

Practice Questions
View allKoppen's classification of climate is based primarily on which two elements?
- A.Air pressure and wind direction
- B.Monthly mean temperature and precipitation
- C.Latitude and altitude
- D.Soil type and drainage
Show answer
Koppen, who was a botanist as well as a climatologist, held that natural vegetation is the best single index of climate, and he fixed his boundaries using the monthly values of temperature and rainfall that vegetation belts seem to follow.

- A.As
- B.Aw
- C.Amw
- D.Cwg
Show answer
The code stands for a monsoon climate with a short dry season: the Malabar coast is hot in every month, so the capital A applies, and it receives extremely heavy rain from the south-west monsoon, leaving only a brief dry spell.

- A.Coromandel coast of Tamil Nadu
- B.Konkan coast of Maharashtra
- C.Coast of Odisha
- D.Coast of Gujarat
Show answer
This coast lies in the rain shadow of the Western Ghats while the south-west monsoon blows, so its summer is comparatively dry, and it gets most of its rain between October and December from the retreating monsoon and the north-east monsoon, which is exactly what the small letter s records.

- A.Sikkim
- B.Himachal Pradesh
- C.Arunachal Pradesh
- D.Meghalaya
Show answer
The capital D marks a cold snow forest climate in which the coldest month falls below minus three degrees Celsius, f marks the absence of a dry season and c marks a short summer with fewer than four months above ten degrees Celsius, and in the standard table for India…
Read the full explanation →In the Koppen code Cwg used for the Ganga plain, the small letter g denotes
- A.Glacial influence on the climate
- B.Gangetic type of temperature, the hottest month coming before the solstice
- C.Grassland vegetation
- D.Greater annual rainfall than evaporation
Show answer
Over most of the Ganga plain the temperature rises steadily through the spring and peaks in May, before the rains break, after which cloud and moisture bring the readings down, and Koppen gave this particular annual march of temperature its own letter.
