intertropical convergence zone

/ ĭn′tər-trŏp′ĭ-kəl /

1. A broad area of low atmospheric pressure located in the equatorial region where the northeasterly and southeasterly trade winds converge, extending approximately 10° north and south of the equator. As warm, humid air converges on this zone, it rises and cools, forming clouds and frequent, heavy showers. The doldrums occur within the intertropical convergence zone.
