Question
Long Answer Question:
Give a brief account of the climate of the Equatorial region.
Solution
The Equatorial region is characterized by uniform high temperature and heavy rainfall throughout the year. This is why there is little seasonal variation in climatic conditions in this region.
- This kind of climatic condition is due to the high angle of incidence of the Sun’s rays. The angle of incidence varies only between 66 V2° and 90° during the year.
- Temperature ranges between 25° C and 30° C with an annual range of about 2° C.
- Rainfall is well distributed during all the months of the year. The amount ranges from 150 cm to 350 cm or more. Rainfall is of Convectional origin. The intense heating of the atmosphere due to solar radiation causes convectional ascent of air leading to a cooling of air condensation, the formation of clouds, and rainfall in the afternoon. But the mountain regions experience Orographic rainfall.
- Thus the equatorial region has a combination of high temperature and high humidity but the climate is not unbearable because of cloudiness and heavy rainfall.
