Stochastic-Dynamic Parameterizations in Numerical Weather PredictionJudith Berner
This talk will give a brief overview on the stochastic parameterization efforts at ECMWF in the context of probabilistic weather foreasting. The first is aimed at injecting a fraction of dissipated energy into the resolved flow ("stochastic backscatter")and uses a cellular automaton as nonlocal pattern-generator. The second tries to improve the representation of tropical variability by introducing stochastic cloud-clusters on the supergrid scale.
