The tropics are the regions of Earth surrounding the Equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt.
The tropics have been historically defined as lying between the Tropic of Cancer and Tropic of Capricorn, at latitudes 23°26′09.7″ (or 23.43603°) 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]
The Tropic of Cancer, also known as the Northern Tropic, is the Earth's northernmost circle of latitude where the Sun can be seen directly overhead. This occurs on the June solstice, when the Northern Hemisphere is tilted toward the Sun to its maximum extent. [1] It also reaches 90 degrees below the horizon at solar midnight on the December ...
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 reason the rain belt is situated near the tropics can be attributed to the fact that the Sun's radiation is strongest near the equator, which is located in the middle of the tropics. This solar radiation generates large amounts of heat near the equator. [1] [2] This causes the air at
The Torrid Zone is also known as the tropics. This zone is bounded on the north by the Tropic of Cancer and on the south by the Tropic of Capricorn; these latitudes mark the northern and southern extremes in which the Sun passes [a] directly overhead. This happens once annually on these cusps, but in the tropics proper, the Sun passes overhead ...
Desert areas situated along the west coasts of continents at tropical or near-tropical locations characterized by frequent fog and low clouds, although these places rank among the driest on earth in terms of actual precipitation received, can be labeled BWn with the n denoting a climate characterized by frequent fog.
The atmosphere of planet Earth: The tropopause is between the troposphere and the stratosphere. Rising from the planetary surface of the Earth, the tropopause is the atmospheric level where the air ceases to become cool with increased altitude and becomes dry, devoid of water vapor.
