Taiwan, located at the subtropical zone in western Pacific Ocean, suffers the damage from 3.5 typhoons on average yearly, mainly during July to October, and several storms year-round. According to the statistics suggested by Water Conservancy Agency of Ministry of Economic Affairs, annual lost due to typhoon includes about three thousands of houses damaged and one hundred and twenty-eight thousands millions collars of loss. This research has collected data relation to typhoons allotted among many agencies. By analyzing of cross-correlation between the data, the results show that the accumulative rainfall and scale of disaster depends on different paths of typhoon. According to statistics, each typhoon causes loses about 2 billion dollars including the loss of agriculture, fishery, human casualty, and building collapses, There is also an evidence to show when the amount of accumulative rainfall surpassed 200mm in Northern, 300mm in Midland, 350mm in Southern and 300mm in Eastern area of Taiwan, it will be increases the probability of flood to 40% in each regions. Besides, the all typhoons© which appear during fall, coming from the south of Taiwan are 60% of all. Those typhoons during fall no matter coming from the east cr west of Taiwan will certainly bring a great quantity of rainfall in Taiwan eastern area because of their counterclockwise rotation and the influence of northeast monsoon. Lastly. the northwest typhoon which passes through the north of Taiwan will make two obvious mass of rainfall in north and midst of Taiwan.
