According to G. T. Trewartha's scheme of climate classification, 'Caw' type of climate is found in which parts of India ?

Question

Accepted Answer

According to G. T. Trewartha's scheme of climate classification, the 'Caw' type of climate is found in the Northern Plains of India. Here's why:

*   **Why Option 1 (Northern Plains) is correct:** Trewartha's 'Caw' climate type signifies a humid subtropical climate with dry winters. The Northern Plains of India, particularly the Indo-Gangetic plain, experience hot, humid summers and relatively dry winters. This aligns perfectly with the characteristics of the 'Caw' climate classification. The region receives significant rainfall during the monsoon season (summer) and experiences a distinct dry period during the winter months.

*   **Why Option 2 (Western Desert) is incorrect:** The Western Desert of India, primarily the Thar Desert, is characterized by an arid climate. This region experiences very low rainfall, high temperatures, and a lack of humidity. This climate is classified differently under Trewartha's system, likely as a dry climate type (B). The 'Caw' classification, with its emphasis on humidity and distinct wet/dry seasons, does not apply to the arid conditions of the Western Desert.

*   **Why Option 3 (Deccan Plateau) is incorrect:** The Deccan Plateau experiences a variety of climate types depending on the specific location. While some parts may have characteristics similar to 'Caw', the overall climate is more complex and influenced by factors like elevation and proximity to the coast. The Deccan Plateau generally has a tropical savanna climate (Aw) or a tropical wet and dry climate, which is distinct from the humid subtropical climate (Caw) found in the Northern Plains.

*   **Why Option 4 (Coastal Plains) is incorrect:** The Coastal Plains of India experience a tropical monsoon climate. These regions have high humidity and rainfall throughout the year, with a shorter dry season compared to the Northern Plains. This climate is typically classified as Am (tropical monsoon) or Af (tropical rainforest) under Trewartha's system, depending on the specific rainfall patterns. The 'Caw' classification, with its emphasis on a distinct dry winter, does not accurately represent the climate of the Coastal Plains.
