Evaluation of cloudiness and snowfall simulated by a semi-spectral and a bulk-parameterization scheme of cloud microphysics for the passage of a Baltic heat cyclone

The differences in the concepts of two different parameterizations of cloud microphysics are analyzed. Simulations alternatively applying these parameterizations are performed for a Baltic heat cyclone event. The results of the simulations are compared to each other as well as to observed distributi...
