 Abstract

The Weather Research and Forecasting (WRF) model is used to investigate the horizontal spatial resolution sensitivity by simulating the 1953 Dutch storm, the grid sizes are 27, 9, 3, 1, 0.5 km from domain 1 to domain 5 respectively. Overall, the the probability density functions of wind speed of all time do not show higher resolution corresponding to higher maximum wind speed and more possibility to detect stronger winds. Because finer resolution domains feature a relatively weak model of wind intensity than coarser resolution domains. In the case, simulations are used two PBL scheme, YSU and Shin-Hong scheme. Three measurement stations with historical meteorology observation in 1953 are selected, Schiphol Netherlands, Leeuwarden Netherlands and Bentwaters United Kingdom. By comparison the measured data and all simulated data, the result from Shin-Hong scheme at the inner domain (d05) perform the best wind speed.
