उत्तर
The Inter-Tropical Convergence Zone (ITCZ) is a low-pressure area near the equator where the trade winds from the Northern and Southern Hemispheres converge. This convergence causes warm, moist air to rise, leading to cloud formation, heavy rainfall, and thunderstorms.
In summer, the ITCZ shifts northward (around 20° to 25° N) and is known as the monsoon trough, playing a key role in the development of the southwest monsoon in India. In winter, the ITCZ moves southward, and winds reverse, leading to the northeast monsoon. The ITCZ plays a crucial role in shaping tropical climates and weather patterns.
