Application of Polynomial Translation Method to Prediction of Annual Maximum Wind Speeds

[[abstract]]Statistics of 10 minute mean wind speeds have been investigated for the simulation of annual maxima in previous researches. Yearly variations of skewness and kurtosis are found highly correlated in most sites. Extremely large skewness or kurtosis values are linearly proportional to annual maxima. In this research, the polynomial translation method is applied. The approximation sheet proposed by Edgeworth (1898) is modified to provide a wider range of moment parameter generations. Mean and standard deviation of four moments are calculated to examine the effect on the scale and location parameters of extreme value distribution model. Once the moment parameters are properly estimated for a specific site, even short of sample number, such prediction of annual maxima can provide good information for wind hazard model.[[sponsorship]]高雄大學[[conferencetype]]國內[[conferencedate]]20121019~20121019[[booktype]]電子版[[iscallforpapers]]Y[[conferencelocation]]高雄, 臺
