Climatic Regions of the World

Topic Content:

The world is made up of several climatic regions. The geographer’s approach to classifying the climatic regions of the world uses the maximum and minimum temperatures and the temperature range as well as the total and seasonal distribution of precipitationPrecipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. It comes in many forms, like rain, sleet, and snow. More.

The major climatic regions of the world are;

Equatorial Climatic Region:

This is between latitude 5ºN and 10ºS, North and South of the equatorThe Equator is Zero degrees (0°) latitude. The Sun is directly overhead the equator at noon on the two equinoxes (March and Sept. 20 or 21). The equator divides the globe... More respectively. There is heavy precipitation of about 150 cm per year. This region gets very hot, and due to this, the mornings are mostly bright and sunny while evenings receive convectional rainfallConvectional rainfall happens when the Sun heats the Earth’s surface, causing the air above it to warm up. The warm, moist air becomes lighter and rises rapidly. As it rises, it... More. Thunder and lightning accompany the torrential rainfall.

The Amazon Basin (South America), Zaire Basin (Africa, especially Western Africa), and South-East Asia (mainly islands) are three well-defined regions of this category.

The Savannah or Sudan Climate:

It is located between 10ºN and 20ºS of the Equator. It is regarded as a transitional climate between the equatorial forests and the trade wind hot deserts. It exists within the tropics and is best developed in the Sudan where the dry and wet seasons are most distinct, hence its name the Sudan Climate . 

This climate is characterised by alternating hot, rainy
