THE HOT, WET EQUATORIAL CLIMATE

Distribution
-Is found between 5° and 10°N and S of the equator. Its greatest extent is found in the lowlands of the Amazon, Congo D.R, Malaysia and the East Indies. -Further away from the equator, the influence on the on-shore Trade Winds gives rise to a modified type of equatorial climate with the Monsoon influences. -Within the tropics, the equatorial highlands have a distinctively cooler climate, modified by altitude such as the Cameron highlands, northern Andes and Kenyan highlands in East Africa

CLIMATE
1. Temperature
- The most outstanding feature of an equatorial climate is its great uniformity of temperature through out the year - The mean annual temperatures are always around 27°C with very little variation. -there is no winter.

-cloudiness and precipitation help to moderate the daily temperature so that even at the equator itself the climate is bearable. -regular land and sea breezes also assist in maintaining a truly equable climate. -the diurnal range is small and so is the annual range.

Figures below illustrate the rhythm of climate experienced in two different equatorial regions, one on lowland (Kuala Lumpur) and the other on the highland (Bogota).
