Equatorial trough or low-pressure belt is commonly known as the?

The Equatorial trough or low-pressure belt is commonly known as the "doldrums". The doldrums are characterized by calm, light winds, and unstable weather conditions due to the rising warm air that creates low pressure. It is located near the Equator and is also known as the Intertropical Convergence Zone (ITCZ). Ships in the past would often get stuck in the doldrums due to the lack of wind, which could lead to long delays in their voyages.
