Tropics. The tropics are the regions of Earth surrounding the Equator. They are defined in latitude by the Tropic of Cancer in the Northern Hemisphere at 23°26′10.0″ (or 23.43612°) N and the Tropic of Capricorn in the Southern Hemisphere at 23°26′10.0″ (or 23.43612°) S. The tropics are also referred to as the tropical zone and the ...
Tropical climate is the first of the five major climate groups in the Köppen climate classification identified with the letter A. Tropical climates are defined by a monthly average temperature of 18 °C (64.4 °F) or higher in the coolest month, and feature hot temperatures all year-round. Annual precipitation is often abundant in tropical ...
A tropical cyclone is a rapidly rotating storm system with a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is called a hurricane ( / ˈhʌrɪkən, - keɪn / ), typhoon ...
Tropical cyclones use warm, moist air as their source of energy or fuel. As climate change is warming ocean temperatures, there is potentially more of this fuel available. [2] Between 1979 and 2017, there was a global increase in the proportion of tropical cyclones of Category 3 and higher on the Saffir–Simpson scale.
Within the region a tropical cyclone is defined as being a non-frontal low-pressure system of synoptic scale that develops over warm waters, with a definite organized wind circulation and 10-minute sustained wind speeds of 34 kn (63 km/h; 39 mph) or greater near the centre. [26]

Tropical wave. A tropical wave (also called easterly wave, tropical easterly wave, and African easterly wave ), in and around the Atlantic Ocean, is a type of atmospheric trough, an elongated area of relatively low air pressure, oriented north to south, which moves from east to west across the tropics, causing areas of cloudiness and ...
Tropical geography refers to the study of places and people in the tropics. When it first emerged as a discipline, tropical geography was closely associated with imperialism and colonial expansion of the European empires as contributing scholars tended to portray the tropical places as "primitive" and people "uncivilised" and "inferior".
