A Humid Tropical Climate

A humid tropical climate is experienced in equatorial regions of the world: West Africa, South East Asia, Northern Australia and South America (for example, the Amazonian rainforest in Brazil).

• Average annual rainfall is over 2000 mm.

• The range of temperature over the year is 1 degree celsius. The temperature is not seasonal.

The humid tropical climate is caused by:

• The equatorial location. The sun is therefore overhead for most of the year. The rays are concentrated on a small area causing high temperatures. 

• Convectional rainfall. The sun in the morning evaporates the water. Storm clouds form and heavy rainstorms occur in the afternoon.
