—Wind speed data for 2010 at eight stations located
in three coastal areas of Taiwan were used to fit three kinds of
Weilbull distributions in this study. Bimodal Gamma-Weibull
distribution is examined the best among three distributions for
all wind speed data comparing three tests for goodness-of-fit.
Key indicators for a bimodal distribution are the weighting
parameter approaching 0.5, variation of peak speeds of monthly
distribution and peak speed ratio. Topographical effect of high
central mountains of Taiwan on offshore wind speeds at
southern Taiwan is stronger than at northern Taiwan. It
explains that the distribution of offshore wind speeds is bimodal
at northern Taiwan and unimodal at southern Taiwan.
