Consider the following statements I. In the month of july the Inter Tropical Convergence Zone is located in the Indo Gangetic plain. II. Northen Inter-Tropical Convergence Zone is the zone of clouds and heavy rainfall. Which of the statement given above is/are correct?
Explanation
Statement I is correct as the Inter Tropical Convergence Zone (ITCZ) shifts northwards during the summer due to the heating of the Indian subcontinent. In July, it is typically located around 20°N-25°N latitudes, specifically over the Indo-Gangetic plain, where it is often referred to as the 'monsoon trough' [3][t1]. Statement II is also correct; the ITCZ (including its northern boundary, NITC) is a low-pressure zone where trade winds converge, leading to ascending air, convective activity, and the formation of a band of clouds [c1][c2]. This zone is characterized by frequent thunderstorms and heavy rainfall as it follows the sun's zenith point [t2][t6]. The seasonal migration of this zone is a primary driver of the Indian summer monsoon, concentrating heavy rains over northern India in July [t4].
