Rainfall is heaviest in the tropics - areas whose latitude is less than 23.5 degrees north or south of the equator and which receive a nearly constant amount of solar energy throughout the year. The water holding capacity of the air increases with rise in temperature. The equatorial region, which receives the most solar radiation and is very warm, contains extremely moist air. In addition, the northern trade winds meet the southern trade winds in this region to create the Inter-tropical Convergence Zone (ITCZ) - a band around Earth where moist tropical air is forced upward and heavy rain showers and frequent thunderstorms are produced. During the course of a year, the ITCZ migrates with the most direct angle of sunlight. When it is summer in the northern hemisphere, the ITCZ shifts towards the north; when it is winter in the northern hemisphere, the ITCZ shifts toward the south.

It is warmer than surrounding areas, causing more evaporation, causing more rain fall.

Solar radiation generates large amounts of heat near the equator, providing tropical regions with higher temperatures than most other regions on Earth.

There can't be any "why" like that, because the Equator is smack dab

in the middle of the Tropics, all the way around the Earth.

Is the sun higher in hot countries?

Yes, the sun is always high in the sky in the tropics. At the equator the sun is always higher at noon than it ever gets in Britain.


What region have seasons marked by rainfall rather than temperature?

The Tropics


Why are there more plants in the tropics than in the desert?

There is much more rainfall in the tropics than in the desert which supports a greater number and variety of plants.


Why does the temperate zone have lower temperatures than the tropics?

Because the temperate zone is in the lower southern hemisphere and the tropics are closer to the equator.

tropical regions


What tropics are in the Philippines?

No, the tropics are larger than the Philippines (they run round the whole planet north and south of the Equator. Thus the question should be :- "Are the Philippines in the tropics" The answer to that question is "Yes" (see the map of the tropics in the related link below.

Does the sunlight hits almost straight on near the equator?

More Than "almost." the sun hits right on the equator. In fact, if you have a flagpole on the equator, there will be no shadow at noon. But the equator is not the only place where this happens. This happens Up to the tropics (tropic of cancer and tropic of Capricorn).


What causes greater thermal conduction at the earth's surface?

The earth is spherical, causing different distance to the sun. The middle part of the earth known as the Equator, is the closet to the sun, causing higher temperature than the other parts, the Tropics Of Cancer and Capricorn are above and below the Equator causing low temperature than that of the equator. And followed by the Arctic and Antarctic region, which are the coldest part of the earth because they are the farthest from the sun.


Would a city at lower latitude have a higher average temperature than a city at higher latitude?

Yes. Since latitude is measured in degrees north or south of the Equator (0° latitude), the lower latitude numbers are closer to the tropics, while the higher ones are comparatively closer to the poles. Although it is not always true, locations at "lower" latitude numbers will generally be warmer than locations at "higher" numbers.
