Previous Year Question
Which one of the following is the characteristic climate of the Tropical Savannah Region?
Rainfall throughout the year
Rainfall in winter only
An extremely short dry season
A definite dry and wet season
Correct Answer: D
Detailed Solution
Tropical savannah climate is also called the tropical wet-and-dry climate. It generally experiences high temperatures throughout the year.
The most important characteristic of this climate is the occurrence of a distinct wet season and a distinct dry season.
The wet season occurs when the rain belt or Intertropical Convergence Zone approaches, whereas the dry season occurs when it moves away and dry trade winds or high-pressure conditions become influential.
Option (a) is incorrect because rainfall does not occur throughout the year. Option (b) is incorrect because rainfall is not confined only to winter. Option (c) is also incorrect because the dry season is distinct and is not necessarily extremely short.
Therefore, the characteristic climatic feature of the savannah region is a definite dry and wet season.
