Question

Which of the following statements are correct regarding the ITCZ and its influence on India's climate?

1. The ITCZ is a low-pressure zone where trade winds converge.

2. In July, the ITCZ is located around 20°N-25°N latitudes over the Gangetic plain.

3. The shift of the ITCZ leads to the reversal of winds from northeast to southwest during winter.

• A. 1 & 2
• B. 2 & 3
• C. 1 & 3
• D. All are correct

Answer 1

Answer:

D. All are correct

• The ITCZ is a low-pressure zone where trade winds converge.- This statement is correct. The ITCZ is indeed a low-pressure belt around the equator where the northeast and southeast trade winds meet, causing air to rise and creating a zone of convergence.

• In July, the ITCZ is located around 20°N-25°N latitudes over the Gangetic plain. - This statement is correct. During summer (June-July), the ITCZ shifts northward and is positioned over the Gangetic plains. This northward movement is critical for the Indian summer monsoon.

• The shift of the ITCZ leads to the reversal of winds from northeast to southwest during winter. - This statement contains an error. The statement describes the opposite of what actually happens. During winter, the ITCZ shifts southward, which leads to a reversal of winds from southwest to northeast (not northeast to southwest). The northeast monsoon or winter monsoon is characterized by winds blowing from northeast to southwest.
