Abstract:
Within this chapter the Hadley Circulation, the Monsoon System, Easterly Waves, Tropical Cyclones and the Walker Circulation are discussed. While the Hadley Circulation and the Monsoon System explain different air flow systems in a mainly meridional sense, a secondary system of latitudinal wind flow is governed by the Walker circulation which is decisive for the formation of La Niña and El Niño events. Apart from the long-term seasonal and nonseasonal variations of the tropical atmosphere, the climate of the Tropics is also affected by more frequent tropical weather disturbances. One of them are large-scale planetary waves which produce greater amounts of rainfall in many maritime tropical regions. These disturbance lines sprawl in a meridional direction from east to west and are called easterly waves.
