The tropical zone generally occurs between the Tropic of Cancer (23.3° N) and the Tropic of Capricorn (23.3° S). At the summer and winter solstice, the sun is directly over these latitudes. About 50 million km2 of land occurs within the tropics. The tropical zone can be divided between the inner tropics or equatorial zone and the outer tropics or the inter-tropical zones.
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 ...
