What Is Downdraft?
Air sinking inside or beneath a thunderstorm, usually cooled by rain and evaporation. In technical terms: A convective-scale region of descending air, driven by negative buoyancy from evaporation, melting and sublimation and by precipitation drag, and in supercells also by dynamic pressure perturbations.
