Step 1: Understanding the Concept:
The ITCZ is a low-pressure belt encircling the Earth near the equator.
Step 2: Detailed Explanation:
It is the region where the Northeast Trade Winds from the Northern Hemisphere and the Southeast Trade Winds from the Southern Hemisphere meet or converge.
This convergence forces the air to rise, leading to frequent thunderstorms and heavy rainfall.
It is also known as the "Doldrums" because the horizontal winds are often very light or calm.
Step 3: Final Answer:
The ITCZ is characterized by the convergence of the Trade winds.
