The tropics are defined as the region between the Tropic of Cancer in the Northern Hemisphere at 23°26′09.7″ (or 23.43602°) N and the Tropic of Capricorn in the Southern Hemisphere at 23°26′09.7″ (or 23.43602°) S; [8] these latitudes correspond to the axial tilt of the Earth. The Tropic of Cancer is the Northernmost latitude from ...
Tropical climates normally have only two seasons, a wet season and a dry season. Depending on the location of the region, the wet and dry seasons can have varying duration. Annual temperature changes in the tropics are small. Due to the high temperatures and abundant rainfall, much of the plant life grows throughout the year.
The South Temperate Zone, between the Tropic of Capricorn at 23°26′09.7″ S and the Antarctic Circle at 66°33′50.3″ S, covers 25.99% of Earth's surface. The South Frigid Zone, from the Antarctic Circle at 66°33′50.3″ S and the South Pole at 90° S, covers 4.12% of Earth's surface. Earth's climatic zones
Using the Trewartha climate classification eight or more months of the year within the subtropics have an average temperature at or above 10 °C (50 °F). The Köppen climate classification instead classifies the warmest month above 22 °C (71.6 °F) and the coldest above 0 °C (32 °F) or −3 °C (26.6 °F) depending on preference.
The Tropic of Capricorn's position is not fixed, but constantly changes because of a slight wobble in the Earth's longitudinal alignment relative to its orbit around the Sun. Earth's axial tilt varies over a 41,000 year period from about 22.1 to 24.5 degrees and currently resides at about 23.4 degrees. This wobble means that the Tropic of ...
The word "tropical" comes from the Greek tropikos meaning "turn". [5] Thus, the tropics of Cancer and Capricorn mark the extreme north and south latitudes where the Sun can appear directly overhead, and where it appears to "turn" in its annual seasonal motion. Because of this connection between the tropics and the seasonal cycle of the apparent ...
The 2025 Atlantic hurricane season officially begins June 1 and will run for 183 days through Nov. 30.. Tropical activity can form outside these dates because warm water and favorable atmospheric ...
The tropics have been historically defined as lying between the Tropic of Cancer and Tropic of Capricorn, at latitudes 23°26′09.7″ (or 23.43602°) north and south, respectively. [2] According to the American Meteorological Society, the poleward fringe of the subtropics is at latitudes approximately 35° north and south, respectively. [3]
