Relevant rain-induced dynamics near moist convection in the tropics are not resolved by General Circulation Models (GCMs) and the parameterization of its effects is poor. This poses a limitation to the understanding of tropical circulation in particular.
This Associated Visiting Scientist study proposal aims to use the ASCAT-A and -B tandem mission with the Meteosat Second Generation rain product (KNMI) to quantify correlations and lags of heavy/extreme rain with small-scale wind convergence/divergence and vorticity for the purpose of improving our understanding of moist convection and its implications for climate circulation and of convective parameterizations in GCMs.
