Tropic

The tropics are two lines parallel with the equator: the Tropic of Cancer, with 23°27' of Northern Latitude; and the Tropic of Capricorn with 23°27' of Southern latitude. The names of Cancer and Capricorne were allotted according to the position of the sun in the astrological Zodiaque. One also indicates under the name of tropics the areas of the world located close to these lines ( to live in the Tropics ), in particular the zones littoral and the islands of these areas.

Characteristics

The part of the sphere located between the two tropics, including/understanding Ecuador, includes/understands all the points of the Ground where the Sun appears with the zenith at solar midday one or twice in the year. In the north of the Tropic of Cancer or in the south of the Tropic of Capricorn, the sun never reaches a rise in 90° and is never with the vertical of the ground. On the same tropics, the Sun reaches the zenith once the year, at the time of the Solstice.

When the sun reaches the zenith of the Tropic of Cancer, it is the summer (in June) in the northern hemisphere and the winter in the southern hemisphere, and conversely when which it reaches the zenith Tropic of Capricorn (December). Between these two seasons the Sun passes to the vertical of the equator the day of spring in its movement about the north and the day of the autumn in its movement towards the south.

Near the equator, one generally meets a climate with abundant high temperatures and precipitations all the year: it is the equatorial Climat. On the other hand, close to the tropics (Cancer or Capricorn), the year is often remembered by a Saison dries and a Rain season, therefore variable Précipitations, whereas the temperature is high throughout the year, which one describes as tropical Climat.

However, the dominant winds, the marine currents, the presence or not of an important continental mass have such an influence on the climate of a given area which one observes of many places where, although one is on the level of a tropic, climate is not tropical (for example the center of Australia or the Sahara, where a rain season ago); and of the areas or the climate is " tropical" without one being in the Tropics (it is the case of Kenya, country located on the equator but of which the essence of the territory has a definitely tropical climate).

Great tropical areas

The areas located in climate at tropical mode itself are located mainly in Central America and South America, the center and part of the south of Africa, the north of Australia and part of Indonesia. The remainder of the intertropical zone is divided primarily between a desert climate (especially in Africa), equatorial or of monsoon (especially in Asia).
