| Summary: | 碩士 === 國立臺東大學 === 進修部環境經濟資管碩專(假日) === 105 === Taiwan is located in the northwestern Pacific, perennial summer and autumn typhoon invasion. Central Weather Bureau (CWB) of Taiwan reports that there are statistically 3.5 typhoons affect Taiwan each year. Nowadays because of global warming caused by climate change, not only the number of typhoon affect Taiwan increased, severe typhoon frequency increases and the short time heavy precipitation and cumulative precipitation also caused by typhoon significantly. The researcher analysis data of the typhoon track and the accumulated precipitation, find out the precipitation model and that could be referred for typhoon disaster prevention.
This research data are from the typhoon invasion data and research of precipitation data in rain detection station, which were announced by the CWB in past decade(2006-2015). First, according to the main factors of affected typhoon precipitation – typhoon track and typhoon intensity as the basis of precipitation data classification to use the Spatial interpolation of the Geostatistics –Kriging method estimates the precipitation of unknown districts, and then further to obtain the precipitation in the whole districts. Finally, further analyze the relationship of typhoon track, and the precipitation in every district and find out the precipitation method. Finally, further conducted the verifications in year 2016. The result shows that the number of precipitation stations in the district affects the accuracy, more numbers of the stations, higher accuracy.
