Three principal factors control the features of South America’s climate.
The subtropical high-pressure air masses over the South Atlantic and South Pacific and their seasonal shifts in position, which determine both large-scale patterns of wind circulation and the location of the rain-bearing intertropical convergence zone (ITCZ).
The presence of cold ocean currents along the continent’s western side, which affect both air temperatures and precipitation along the Pacific coast; on the Atlantic coast, warm currents are predominant.
The orographic barrier of the Andes produces a vast rain shadow over much of the southern tier of the continent.
