A new database for the annual maximum wind speeds and directions from 1929 to 1999 at 155 meteorological stations are established and errors in conventional databases are corrected. The correction factors for various anemometers are proposed and their accuracy was examined. As a result, the variations in averaged annual maximum wind speeds almost disappear and variations of 100-year wind speeds with the statistical period decrease. Comparing the sampling errors in 100-year wind, it was found that the proposed correction factors are more accurate than conventional those.
