Statistical Modelling of Extreme Rainfall in Taiwan
In this study,the annual maximum daily rainfall from 1911 to 2010 are modeled for 6 stations in Taipei,Taichung,Tainan,Hengchun,Hualien,and Taitung.We fit the rainfall data both with stationary and non-stationary generalized extreme value (GEV) distribution,and further estimated future patterns based on the best fitted model.The non-stationary model used the location and scale parameter in the GEV distribution as a function of time to detect the temporal trend of the maximum rainfall.The results suggest that non-stationary GEV and Gumbel distribution provide best fit for Haulien and Taitung,respectively.The return levels of the stationary models for 4 stations and their 95% confidence intervals (CI) are provided.In addition,the return period of Typhoon Morakot is also calculated based on stationary models in this study.
