With the big Sahelian climatic aridities, the study of lithometeores has increasingly aroused the interest of the scientific community. The aim of this article is to gain a better knowledge of these types of weather through their complex typology and of the factors through which they originate. It also points out to those new tendencies that are the direct consequence of climatic aridities and of the drastic changes which have recently occurred in the Sahelian ecosystems.
