27 de jun. de 2024 · The intertropical convergence zone is a belt of converging trade winds and rising air that encircles Earth’s lower atmosphere near the Equator. The rising air in this region produces high cloudiness, frequent thunderstorms, and heavy rainfall; the doldrums, oceanic regions of calm surface air, occur within the zone.
Hace 3 días · Tropical cyclone - Location, Patterns, Forecasting: Tropical oceans spawn approximately 80 tropical storms annually, and about two-thirds are severe (category 1 or higher on the Saffir-Simpson scale of intensity). Almost 90 percent of these storms form within 20° north or south of the Equator.

Hace 4 días · First, most of the continent—which extends from 35° S to about 37° N latitude—lies within the tropics. Second, the near bisection of the continent by the Equator results in a largely symmetrical arrangement of climatic zones on either side.
Hace 1 día · Measured along with the Lualaba, the main tributary, the Congo River has a total length of 4,370 km (2,720 mi). It is the only major river to cross the Equator twice. [10] The Congo Basin has a total area of about 4,000,000 km 2 (1,500,000 sq mi), or 13% of the entire African landmass.
Hace 6 días · Tropical cyclones are like giant engines that use warm, moist air as fuel. That is why they form only over warm ocean waters near the equator. The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface.
