Abstract: Records of extreme annual gust velocities from 11 weather stations in central-southern Brazil, classified according to orientation (octants) and type of storm (TS and EPS winds), result in 176 sectorial wind series, with an average length of 25 years. The extreme value type I distribution fits better the records than either the type II or other distributions, while the type II shows superior fit to the extreme dynamic pressures. The correlation between wind velocity and temperature is also studied. Finally, a model is proposed for predicting the wind climate in specific regions, considering wind orientation and storm type.
