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.
