Question: 1 / 400

What occurs in the Doldrums region?

Winds are very strong

Winds cancel out

In the Doldrums region, also known as the Intertropical Convergence Zone (ITCZ), the notable characteristic is that the winds tend to cancel out or become very light and variable. This phenomenon occurs where the trade winds from the Northern and Southern Hemispheres converge, creating a zone of calm. Because the trade winds meet, they can effectively neutralize each other, leading to periods of little to no wind at the surface.

This calmness is characterized by a lack of consistent airflow, which contributes to the humid and often stormy weather typical of the region, including the development of towering cumulus clouds and thunderstorms. The Doldrums experience frequent shifts in wind direction as the convergence zone moves with the seasons, but the primary feature is indeed the cancellation of the winds as they collide head-on, resulting in very light winds.
