is known as the West African monsoon. It is a seasonal wind system that blows over the region bringing moisture and precipitation from the Atlantic Ocean. The monsoon season typically begins in late May or early June and lasts until September or October, bringing much-needed rainfall to the region. The wind system is caused by the temperature difference between the land and the ocean, as well as the movement of the Earth's rotation.
The wind that brings rains to West Africa is called the Inter-Tropical Convergence Zone (ITCZ). It is a low-pressure belt formed by the meeting of the trade winds from the northern and southern hemispheres. As the trade winds converge near the equator, warm, moist air rises, creating clouds and precipitation. This wind pattern shifts seasonally, resulting in rainy seasons in West Africa.
