Geographic information of west Africa

The climate of West African countries is dominated by tropical rainforests for three reasons:

1) West Africa is located near the equator. It is controlled by the equatorial low-pressure belt all the year round, with updraft, which easily turns into clouds and rain when it is cold. The temperature is the highest at 2 pm. When it is cold, a large amount of water vapor evaporates into the air. When it is cold, it will condense and take some time to accumulate, so there will usually be a convective rain around 4 pm.

2) Topographic factors are also a cause of the rainforest climate. As most of West Africa is located in Congo Basin, as we all know, the topography of the basin is not easy to dissipate heat, which further aggravates the characteristics of rainforest climate.

3) There is a Guinean warm current (belonging to compensation current in nature) along the coast, which has the functions of warming, humidifying and increasing salt, and also contributes to the formation of rainforest climate.

The geographical location of West Africa is about (equatorial latitude, east longitude 15 degrees).

Because West Africa is located near the equator, there are two sunny days in a year, March 2 1 Sunday and September 23. There are no four seasons in West Africa. There are two situations here:

1) Africa is very special. There should be a rainforest climate near the equator, but the existence of the East African Plateau makes the rainforest climate limited to the west of Lake Victoria (near 30 degrees east longitude). In other words, the rainforest climate here is incomplete, the tropical rainforest and savanna climate coexist, and the grassland climate is divided into two completely different seasons.

2) Tropical rain forests, as just said, have no obvious seasonal changes.
