Question

Why doldrums are called as wind convergence?

Answer 1

The falling air then reverses direction and sweeps back towards the equator. Thesewinds are called the Trade Winds and were used by early sailors to propel their sailing ships towards the New World and Caribbean. ... The area where the Trade Winds meet is known as the ITCZ: Intertropical Convergence Zone.

Answer 2

Answer:

Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator. Here, the prevailing trade winds of the northern hemisphere blow to the southwest and collide with the southern hemisphere’s driving northeast trade winds.

Due to intense solar heating near the equator, the warm, moist air is forced up into the atmosphere like a hot air balloon. As the air rises, it cools, causing persistent bands of showers and storms around the Earth’s midsection. The rising air mass finally subsides in what is known as the horse latitudes, where the air moves downward toward Earth’s surface.

Because the air circulates in an upward direction, there is often little surface wind in the ITCZ. That is why sailors well know that the area can becalm sailing ships for weeks. And that’s why they call it the doldrums.
