  1. 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. Known to sailors around the world as the doldrums, the Inter ...

  2. The Doldrums is a low pressure area from 5°N to 5°S of the Equator. Winds are famously calm here, with prevailing breeze disappearing altogether at times, making it extremely difficult to navigate through. It's a place for trade winds to meet other trade winds. The Doldrums is also known as the Inter Tropical Convergence Zone (ITCZ), because ...

  3. The ITCZ is visible as a band of clouds encircling Earth near the Equator. The Intertropical Convergence Zone (ITCZ / ɪtʃ / 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. It encircles Earth near the thermal ...

  4. Oct 10, 2024 · The doldrums are part of the Inter-Tropical Convergence Zone, a band of clouds along the equator that is notoriously hard to observe, model, and study. As a result, the doldrums are one of those “fundamental things that no one had thought about, even though it’s something we talk about in every intro [atmospheric sciences] class,” says physical oceanographer Kay McMonigal, who was not ...

  5. doldrums, equatorial regions of light ocean currents and winds within the intertropical convergence zone (ITCZ), a belt of converging winds and rising air encircling Earth near the Equator. The northeast and southeast trade winds meet there; this meeting causes air uplift and often produces clusters of convective thunderstorms.

  6. Jul 25, 2017 · The ITCZ is the band of bright white clouds that cuts across the center of the Earth. (Photo: NOAA’s GOES Project Science Office) The Intertropical Convergence Zone (ITCZ), also known as the doldrums, is one of the dramatic features of Earth’s climate system. Prominent enough to be seen from space, the ITCZ appears in satellite images as a ...

  7. Sep 11, 2024 · The trade winds begin as warm, moist air from the equator rises in the atmosphere and cooler air closer to the poles sinks. The trade winds are created by a cycle of warm, moist air rising near the equator. The air eventually cools and sinks a bit further north in the tropics. This phenomenon is called the Hadley cell.
