The tropics are defined as the region between the Tropic of Cancer in the Northern Hemisphere at 23°26′09.8″ (or 23.43605°) N and the Tropic of Capricorn in the Southern Hemisphere at 23°26′09.8″ (or 23.43605°) S; [8] these latitudes correspond to the axial tilt of the Earth. The Tropic of Cancer is the Northernmost latitude from ...
Tropical savanna climates, or tropical wet and dry climates, are mainly located between the 10° and 25° north-south latitudes, and often occur at the outer margins of the tropics. Typical regions include central Africa, parts of South America, as well as northern and eastern Australia. [ 16 ]
Tropical ecology is the study of the relationships between the biotic and abiotic components of the tropics, or the area of the Earth that lies between the Tropic of Cancer and the Tropic of Capricorn (23.4378° N and 23.4378° S, respectively). The tropical climate experiences hot, humid weather and rainfall year-round.
500 million years of climate change Ice core data for the past 400,000 years, with the present at right. Note length of glacial cycles averages ~100,000 years. Blue curve is temperature, green curve is CO 2, and red curve is windblown glacial dust (loess). Scale: Millions of years before present, earlier dates approximate.
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 ...
In comparison, both records show that ocean surface and land temperatures behaved differently during the past 25,000 years. During the last ice age, African temperatures were 21 °C, about 4 °C lower than today, while the tropical Atlantic Ocean was only about 2.5 °C cooler. Lead author Johan Weijers and his colleagues concluded that the land ...
In 1953, the National Hurricane Center of the U.S. National Oceanic and Atmospheric Administration started using female names alphabetically for tropical storms and hurricanes in the Pacific 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".
