A preliminary study of this year, we analyze the integral rainfall dataset of typhoon Mindulle (2004) and Aere(2004), and assess the feasibility of the QPESUMS rainfall dataset to make the early waring of debris flow. The results will help to improve the precipitation estimation and to establish the rainfall index in debris flow warning.土石流定量降雨估計雷達雨量站debris flowquantitative precipitation estimationradarrain-gaugeQPESUMS土石流潛勢區之雨量估計與即時預報技術發展先期研究
