Tropical Climates(A) Tropical A climates, the most extensive, occupy about 36% of Earths surface, including both ocean and land areas. The trop- ical A climates straddle the equator from about 20 N to 20S, a roughly between the Tropics of Cancer and Capricorn, giving Merida, Mexico the climate type its name. Tropical A climates stretch north ward to the tip of Florida and south-central Mexico, central India, and Southeast Asia. In a climates the coolest month must be warmer than 18C(644F), making these climates truly winterless Consistent daylength and almost perpendicu ar Sun angle throughout the year generate this warmth a climates are subdivided by annual precipitation into s Tropical rain forest [Tropical savanna tropical rain forest Af, tropical monsoon Am, and tropical Tropical monsoon savanna Aw
