LES study of microphysical variability bias in shallow cumulus

Yefim Kogan

Data sets

Controls on precipitation and cloudiness in simulations of trade-wind cumulus as observed during RICO M. C. vanZanten et al.

Short summary
Exact description of cloud microphysical processes is essential for providing accurate weather forecasts. The paper evaluates errors of different methods to account for variability of cloud microphysical parameters, such as cloud water. rain water, and cloud drop concentration. It is found that neglecting cloud variability results in a substantial underestimate of rain development in the short run. Nevertheless the total effect on rain development in the long run may be uncertain due to the fac
