The aerosol- and water vapor-related variability of precipitation in the West Africa Monsoon
The precipitation variability in the West Africa Monsoon (WAM) is affected by many factors. Close to the largest aerosol emission sources (mineral dust from Sahara and Sahel, and biomass burning smokes from Sahel and southern Africa), the WAM provides a natural laboratory to study the possible conne...

The precipitation variability in the West Africa Monsoon (WAM) is affected by many factors. Close to the largest aerosol emission sources (mineral dust from Sahara and Sahel, and biomass burning smokes from Sahel and southern Africa), the WAM provides a natural laboratory to study the possible connections between aerosol, water vapor and precipitation. Possible aerosol and water vapor effects have, however, not been thoroughly investigated. Additionally how aerosol effect is distinguished from environmental water vapor effect is hardly visited. Using long term multi-satellite observations of aerosol, water vapor and precipitation, this study elucidates possible large-scale effects from the absorbing aerosol (primarily mineral dust and carbonaceous aerosol) and atmospheric water vapor on precipitation over the WAM region.
