Climate and seasonality are dominated by the interaction of the intertropical low and subtropical high, the east to west dynamics of the tropical atmosphere, and the distribution of land and sea. The outer tropics are characterized by wet and dry seasons with intrusions of temperate weather systems such as cold fronts. Mean annual temperature at sea level is generally >18°C and ...
