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.

热带辐合带（Intertropical Convergence Zone. ITCZ) ，是南北两半球信风气流形成的辐合地带，又称为赤道辐合带。由于辐合带区的气压值比附近地区的低，也称为赤道低压带或赤道槽等。

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 …

熱帶輻合帶（又譯間熱帶輻合區；英語： Intertropical Convergence Zone ，縮寫：ITCZ），又稱為赤道低壓帶（又譯赤道低氣壓帶、赤道無風帶；英語： Equatorial belt of calms ）或赤道輻合帶，是活躍於赤道的低氣壓帶，南北半球副熱帶高壓帶間氣壓最低的風帶。

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, 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.

赤道辐合带顾名思义就是在风赤道附近发生辐合，赤道辐合带又被称为热带辐合带（itcz）。 2014年9月位于东北太平洋的热带辐合带。 当风场发生辐合的时候会发生什么？

Dec 13, 2006 · The Inter Tropical Convergence Zone, or ITCZ, is a belt of low pressure which circles the Earth generally near the equator where the trade winds of the Northern and Southern Hemispheres come together. It is characterised by convective activity which generates often vigorous thunderstorms over large areas.

The intertropical convergence zone (ITCZ) is an east-west-oriented low-pressure region near the equator where the surface northeast and southeast trade winds meet. As these winds converge, moist air is forced upward, producing cumulus clouds and heavy precipitation. These clouds occur in scattered masses about 100 km (60 miles) across.

Sep 4, 2014 · Rainfall on Earth is most intense in the intertropical convergence zone (ITCZ), a narrow belt of clouds centred on average around six degrees north of the Equator.
