In Koppen's scheme, which climatic type is found on the west coast of India south of Goa?

  1. A.As
  2. B.Aw
  3. C.Amw
  4. D.Cwg

Correct answer

C. Amw

Explanation

The correct answer is C, Amw. 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. Option A is wrong because As means a monsoon climate with a dry summer and is confined in India to the Coromandel coast of Tamil Nadu. Option B is wrong because Aw, the tropical savannah type with a long dry season, covers most of the peninsular plateau south of the Tropic of Cancer, the interior rather than the wet western edge. Option D is wrong because Cwg is a warm temperate type with dry winters and belongs to the Ganga plain and the north-east, well away from the Konkan and Malabar coasts. Fix the pair Amw with the coast south of Goa in memory.

Q1.GeographyEasy

Koppen's classification of climate is based primarily on which two elements?

  1. A.Air pressure and wind direction
  2. B.Monthly mean temperature and precipitation
  3. C.Latitude and altitude
  4. D.Soil type and drainage
Show answer
Correct answer: B. Monthly mean temperature and precipitation

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.

Q2.GeographyMedium

The As type of climate, a monsoon climate with dry summer, is found in India only along the

  1. A.Coromandel coast of Tamil Nadu
  2. B.Konkan coast of Maharashtra
  3. C.Coast of Odisha
  4. D.Coast of Gujarat
Show answer
Correct answer: A. Coromandel coast of Tamil Nadu

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.

Q3.GeographyEasy

In Koppen's classification of Indian climates, the code BWhw, the hot desert type, is given to

  1. A.Eastern Rajasthan
  2. B.Extreme western Rajasthan
  3. C.Southern Punjab
  4. D.North-western Gujarat
Show answer
Correct answer: 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.

Q4.GeographyMedium

Which Indian state alone is given the Dfc code, a cold humid winter with a short summer?

  1. A.Sikkim
  2. B.Himachal Pradesh
  3. C.Arunachal Pradesh
  4. D.Meghalaya
Show answer
Correct answer: C. Arunachal Pradesh

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…

Q5.GeographyHard

In the Koppen code Cwg used for the Ganga plain, the small letter g denotes

  1. A.Glacial influence on the climate
  2. B.Gangetic type of temperature, the hottest month coming before the solstice
  3. C.Grassland vegetation
  4. D.Greater annual rainfall than evaporation
Show answer
Correct answer: B. Gangetic type of temperature, the hottest month coming before the solstice

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.
