Abstract: Regional fine resolution meteorological model was developed in Zhuhai region using Weather Research and Forecasting Model(WRF). With ERA- Interim re- analysis dataset as boundary and initial conditions, long-term annual daily maximum rainfall event simulations were performed to obtain 4km horizontal resolution grid-time series precipitation data. Then, the spatial pattern of the maximum precipitation with different rainfall duration (1 h and 24 h) and return periods (2, 5, 10, 20, 50 and 100 years)were estimated with the WRF model results and generalized extreme value (GEV)distribution. The results support the urban planning for Zhuhai’s disaster prevention and reduction, as well as the local flooding risk evaluation.
