Mécanismes de soulèvement d'aérosols désertiques en Afrique de l'Ouest

Autor: Bou Karam, Diana

Dans le cadre du présent travail de recherche, deux nouveaux mécanismes de soulèvements d'aérosols désertiques en Afrique de l'Ouest, durant la saison de mousson, ont été identifiés: 1- Le premier étant lié aux forts vents turbulents au niv

International audience; So-called ‘dry’ microburst outflows are well known phenomena in desert environments when rain from moist convection aloft evaporates into deep, dry-adiabatic boundary layers. Extreme synoptic scale versions of this convect

International audience; North and West Africa is the world's largest source of mineral dust [e.g. Prospero et al., 2002]. Dust emissions over this region are highest during summer (e.g. Engelstaedter and Washington 2007) and are very variable in time
