This paper deals with high resolution numerical weather prediction experiments for the recent Bangladesh Tropical Cyclone April 1991. This devastating storm resulted in well over 100,000 deaths. The results from global model experiments carried out at a horizontal resolution of 213 waves triangular truncation and from a regional model at a horizontal resolution of 46 km are presented. Recent improvements in the models parameterization of cumulus convection, land surface parameterization the specification of ground wetness, enhanced evaporation over low wind speed regions were included in the sensitivity studies reviewed here.
