Abstract

Impacts of African dust particles on mixed-phase and warm stratiform clouds are investigated using four years of collocated CALIPSO and CloudSat measurements. The results show that dust could enhance ice particle concentrations in stratiform mixed-phase clouds by a factor of 2 to 6 at temperatures colder than-12°C. Obvious drizzle suppression in dusty warm stratiform clouds is also observed. The study suggests that the presence of African dust affect both mixed-phase and warm cloud microphysical properties and processes.
