Description

South Atlantic tropical cyclones are unusual weather events that occur in the Southern Hemisphere. Strong wind shear in the Troposphere, which disrupts the formation of these cyclones, as well as a lack of weather disturbances favourable for development in the South Atlantic Ocean (such as the tropical waves common the in the southern North Atlantic) make any strong tropical system extremely rare. The Inter Tropical Convergence Zone (ITCZ), another potential breeding ground, drops one to two degrees south of the equator, not far enough from the equator for the spin of the Coriolis force to aid development. Water temperatures in the tropics of the southern Atlantic are cooler than those in the tropical north Atlantic.
