World map with the intertropical zone highlighted in crimson Areas of the world with tropical climates. 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′09.9″ (or 23.43609°) N and the Tropic of Capricorn in the Southern Hemisphere at 23°26′09.9″ (or 23.43609°) S.
World map showing the Tropic of Capricorn Relationship of Earth's axial tilt (ε) to the tropical and polar circles. The Tropic of Capricorn (or the Southern Tropic) is the circle of latitude that contains the subsolar point at the December (or southern) solstice. It is thus the southernmost latitude where the Sun can be seen directly overhead.
World map with the middle latitudes highlighted in red Extratropical cyclone formation areas. The middle latitudes (also called the mid-latitudes, sometimes midlatitudes, or moderate latitudes) are a spatial region on Earth located between the Tropic of Cancer (latitudes 23°26′09.9″) to the Arctic Circle (66°33′50.1″), and Tropic of Capricorn (-23°26′09.9″) to the Antarctic ...
Road sign marking the equator near Nanyuki, Kenya. The latitude of the Earth's equator is, by definition, 0° (zero degrees) of arc.The equator is one of the five notable circles of latitude on Earth; the other four are the two polar circles (the Arctic Circle and the Antarctic Circle) and the two tropical circles (the Tropic of Cancer and the Tropic of Capricorn).
Geographical zone. The five main latitude regions of Earth's surface comprise geographical zones, [1] divided by the major circles of latitude. The differences between them relate to climate. They are as follows: The North Frigid Zone, between the North Pole at 90° N and the Arctic Circle at 66°33′50.1″ N, covers 4.12% of Earth's surface.
On the ellipsoid or on spherical projection, all circles of latitude are rhumb lines, except the Equator. The latitude of the circle is approximately the angle between the Equator and the circle, with the angle's vertex at Earth's centre. The Equator is at 0°, and the North Pole and South Pole are at 90° north and 90° south, respectively.
Subtropics. The subtropical zones or subtropics are geographical and climate zones to the north and south of the tropics. Geographically part of the temperate zones of both hemispheres, they cover the middle latitudes from 23°26′09.9″ (or 23.43609°) to approximately 35° north and south. The horse latitudes lie within this range.
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 °F) or higher in the coolest month, featuring hot temperatures and high humidity all year-round. Annual precipitation is often abundant ...
