Difficulty: MediumClimate, Weather Systems, and Monsoon of India

According to Köppen's scheme of climatic classification of India, the extensive region covering the Ganga Plains, eastern Rajasthan, and northern Madhya Pradesh is characterized by a humid subtropical climate with dry winters and hot summers. Which of the following Köppen climate symbols accurately represents this region?

  1. CwgAnswer
  2. B
    Aw
  3. C
    As
  4. D
    BShw

Answer

The correct climate code is Cwg, representing a humid subtropical climate with dry winters found across the Ganga plains.
Köppen classified the climate of the Ganga Plains, eastern Rajasthan, and parts of central India as 'Cwg'. Here, 'C' stands for warm temperate/subtropical climate (coldest month average temperature between -3°C and 18°C), 'w' indicates dry winter season, and 'g' stands for the Ganges type of temperature pattern where the maximum temperature occurs prior to the summer rainy season.

Step-by-Step Solution

1
Identify the geographical region described in the prompt.
The target region encompasses the Ganga Plains, eastern Rajasthan, and northern Madhya Pradesh.
Köppen mapped specific empirical symbols to distinct temperature and rainfall regimes across India.
2
Match the seasonal temperature and precipitation features to Köppen's classification system.
The region experiences hot summers, rainy monsoon periods, and dry winters, fitting the 'Cwg' designation.
In Köppen's nomenclature, 'C' denotes warm temperate/humid subtropical, 'w' indicates dry winters, and 'g' signifies the Ganges type temperature profile.
