Not all places in Africa are hot.

It's just that we have been influenced by the subjective impression of the Sahara Desert in northern Africa since we were young and think that Africa is very hot.

The reason why northern Africa is hot.

First, it is between the Tropic of Cancer and the equator. The relatively high temperature and the rapid evaporation of water vapor.

The second and most important reason is that it is between the equatorial low pressure and the northern subtropical high pressure. The north wind blows all year round. And because it is in the northern hemisphere, the north wind is deflected into the northeast wind by the Coriolis force. And the northeast of northern Africa happens to be the huge Asian continent. There is no water vapor all year round, and a large amount of water vapor evaporates, which leads to the hot and dry northern Africa. The two people above mentioned the equatorial Africa. Because the equatorial region is hot, the water vapor evaporates very quickly. In addition, the equatorial low pressure causes the atmosphere to sink. The atmospheric sinking water vapor condenses into water droplets and often forms a large amount of rainfall in the afternoon. Commonly known as convective rain. So equatorial Africa is humid but not hot. There is also the Congo River, which is second only to the Amazon River in terms of flow.
