In this study we collected typhoon data that attacked Taiwan since 1990. By classifying the invading direction from Northwestern Pacific and South China Sea, we obtained 9 and 8 typhoons from two groups respectively.Total samples amount to 75 were used in the study. Using GMS 5 data, we first derived the parameters such as minimum brightness temperature, mean brightness temperature, standard deviation of brightness temperature and cloud area and cover from satellite data covering the typhoon circulation. Along the distance of 25 km, 50 km, 100 km and 200 km between typhoon and Taiwan land area, observation data were used to test the correlation between satellite parameters and precipitation obtained from statistical results. This study and its on-going research are aimed to provide an objective method using geostationary satellite parameters to forecast the wind strength and precipitation as typhoon invades Taiwan.
