- 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 "doldrums" is a popular nautical term that refers to the belt around the Earth near the equator where sailing ships sometimes get stuck on windless waters. This NASA satellite image shows the Inter-Tropical Convergence Zone, known to sailors around the world as the doldrums.
The Doldrums holds a distinct place in maritime history, having developed a reputation as a potentially deadly zone which could strand ships for weeks on end, causing them to run out of food and drinking water.
Sep 20, 2024 · New research by atmospheric scientist Julia Windmiller indicates that the doldrums are likely caused by sinking air masses, challenging the traditional belief of rising air as the cause and potentially impacting climate predictions.
The Intertropical Convergence Zone (ITCZ / ɪ tʃ / ITCH, or ICZ), [1] known by sailors as the doldrums [2] or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge.
Sep 9, 2024 · For at least a century, scientists have thought that the doldrums’ lack of wind was caused by converging and rising air masses. Now, new research suggests that the opposite may be true.
Oct 9, 2024 · The doldrums occur within the Intertropical Convergence Zone (ITCZ), a band of clouds along the equator where the northeasterly trade winds from the Northern Hemisphere meet and collide with southeasterly trade winds from the Southern Hemisphere.
Sep 11, 2024 · The current explanation, touted by places like the US National Oceanic and Atmospheric Administration, is that hot rising air around the equator causes a region of low...
