Significance of Inter-Tropical Convergence Zone (ITCZ)
- The North-East and South-East trade winds converge in the ITCZ.
- Its Northward and Southward motion controls the rainfall’s spatial distribution.
- It is the section of the plane that is the wettest and does not have a dry season, therefore it is continually hot and humid.
- The monsoon trough is the name given to the ITCZ when it moves over the Ganga plain in the summer (5°N typically north of the equator).
- ITCZ, commonly referred to as the monsoon trough during the monsoon season, is a belt of low pressure that lies between the subtropical high pressure belts of the Northern and Southern Hemispheres.
Write a brief note on Inter Tropical Convergence Zone?
During the monsoon season, India’s climate is hot and muggy, similar to that of South and Southeast Asia. Two of the four seasons that exist in the Indian subcontinent are monsoon seasons. Those are Season of the Southwest Monsoon and The Monsoon Season in the North-East.
The Arabic term mausin or the Malayan word monsin, both of which indicate season, are the origins of the name monsoon. Seasonal winds (rhythmic wind movements) (periodic winds) that change direction with the seasons are known as monsoons. A seasonal wind pattern known as the monsoon moves from the sea to land in the summer and from the land to the sea in the winter. According to some academics, monsoon winds are significant land and sea breezes.
Inter-Tropical Convergence Zone (ITCZ) is one of the important facts to understand the mechanism of the monsoons.
