  Intertropical Convergence Zone

  noun

  Also intertropical convergence zone. a low-pressure belt that encircles Earth near the equator, where the trade winds of the Northern and Southern Hemispheres converge, triggering conditions of heavy rain and thunderstorms, especially over land. Abbreviation: ITCZ.
• intertropical convergence zone
  intertropical convergence zone

  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.

The researchers also found that an atmospheric band near the equator called the "intertropical convergence zone," which produces 30 percent of global precipitation, causes an intense amount of energy transfer, and produces ocean turbulence.
