Jul 18, 2023 · The Inter-Tropical Convergence Zone (ITCZ) appears as a band of clouds consisting of showers and occasional thunderstorms that encircles the globe near the equator. The solid band of clouds may extend for many hundreds of miles and is sometimes broken into smaller line segments.

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 equator though its specific position varies seasonally.

The Intertropical Convergence Zone, or ITCZ, is the region that circles the Earth, near the equator, where the trade winds of the Northern and Southern Hemispheres come together. The intense sun and warm water of the equator heats the air in the ITCZ, raising its humidity and making it buoyant.

intertropical convergence zone (ITCZ), belt of converging trade winds and rising air that encircles Earth’s lower atmosphere near the Equator. The rising air produces high cloudiness, frequent thunderstorms, and heavy rainfall; the doldrums, oceanic regions …

Jul 17, 2019 · The intertropical convergence zone or “ITCZ” roughly forms a band that circumnavigates the Earth near the Equator where the northeast trade winds in the Northern Hemisphere converge with the southeast trade winds in the Southern Hemisphere.

Known to sailors around the world as the doldrums, the Inter-Tropical Convergence Zone, (ITCZ, pronounced and sometimes referred to as the “itch”), is a belt around the Earth extending approximately five degrees north and south of the equator.

Feb 22, 2006 · Figure 1 displays the current position of the ITF during the 1st dekad of April and its previous position during the 3rd dekad of March. Figures 2 and 3 are time series, illustrating the latitudinal positions for the western and eastern portions of the ITF, respectively, and their seasonal evolutions since the beginning of April 2025.

The ITCZ crosses Guyana as it travels to the north and then again as it moves south, giving this country two periods of heavy rainfall each year. The map below shows the northernmost and southernmost positions of the ITCZ.
