Which combination of climatic symbols was proposed by Köppen for the Tropical Dry Climatic region of Rajasthan?

Correct option is B

The correct answer is option (b) Bwhw

Explanation

Köppen’s Climate Classification is a widely used system to categorize global climates based on temperature and precipitation patterns. For the Tropical Dry Climatic region of Rajasthan, the correct climatic symbol is Bwhw. This symbol represents the Tropical Dry Desert Climate, found in regions like West Barmer, North-West Jodhpur, West Bikaner, Jaisalmer, and Ganganagar.

• The B in the symbol stands for Dry Climate (Arid or Semi-Arid).

• The W indicates a Desert Climate.

• The h stands for the Hot type of desert climate, characterized by high temperatures.

• The w at the end of the symbol indicates that the area has winter dryness—meaning the region experiences minimal rainfall during the winter months.

The region is characterized by minimal rainfall, sandy terrain, and sparse vegetation, as described in the additional information section of the climate classification.

Information Booster

• Bwhw represents the Tropical Dry Desert Climate in Rajasthan.

• This climate is found in desert regions where rainfall is minimal and vegetation is sparse.

• The hot desert climate indicates very high temperatures and dryness.

• The winter dryness signifies a lack of rainfall in the cooler months.

• This climate classification system helps in understanding the distribution of vegetation and agricultural activities in arid regions.

Additional Knowledge

(a) Bshw:
This would represent a semi-arid or steppe climate. It’s characterized by less extreme dryness and a little more rainfall than a true desert climate. The "h" signifies hot conditions, but this is not the symbol for the desert regions of Rajasthan.

(b) Bwhw:
This is the correct symbol for the Tropical Dry Desert Climate. It is prevalent in areas like Jaisalmer, Barmer, and Bikaner, which experience extremely hot, dry conditions and have sparse vegetation.

(c) Bshs:
This represents a semi-arid steppe climate with summer rainfall. It is not the correct symbol for Rajasthan’s desert climate, as the region is mostly dry year-round, not specifically during the summer.

(d) Bwhs:
This would indicate a hot desert climate with summer rainfall, which is not typical of Rajasthan's desert region, as it generally lacks significant rainfall in the summer months.
