What is Doldrums? Where is it found?

The equatorial low-pressure belt is basically a zone of high temperature with low pressure. This belt lies between 0⁰ to 5⁰ North and South of the equator. This is the region which gets direct rays from the sun throughout the year. Hence, air is always very warm and hot because of which it becomes a calm region with very little wind. This is known as ‘Doldrums’ (as shown in figure below)

This region is also known as Inter-Tropical Convergence Zone where trade winds converge.
