Convective Entrainment Rate over the Tibetan Plateau and Its Adjacent Regions in the Boreal Summer Using SNPP-VIIRS

The entrainment rate (λ) is difficult to estimate, and its uncertainties cause a significant error in convection parameterization precipitation simulation, especially over the Tibetan Plateau, where observations are scarce. λ adjacent regions, estimated for first time using five-year satellite data reanalysis dataset. cloud base environmental relative humidity (RH) decrease with an increase terrain height. Quantitatively, correlation between RH changes from positive at low heights negative high heights, underlying mechanisms here interpreted. When height below 1 km, large decreases difference moist static energy (MSE) clouds environment increases λ. above related MSE turning point base, because of specific near surface increasing These results enhance theoretical understanding factors affecting pave way improving
