On the Preprediction of the Wind Climate in Seoul Based on Probability Distribution(Weibull Distribution) |
Abstract |
The evaluation of the wind environment around high rise buildings needs wind data. The hourly wind data over 10 years in Seoul obtainded from National Weather Service is analyzed (1981.1.1.~1990.12.31).In the spring the prevailing winds blow from the west, the average wind velocity is 2.9m/s. Summer winds are not as strong as those in the spring, they generally come from the northeast and the average wind velocity is 2.4m/s.The wind speeds tend to be relatively low in the morning(24:00~11:00: 1.9m/s) compared to the afternoon(12:00~23:00;3.05m/s).The probability distribution(weibull Distribution)is employed to predict the wind climate. The Weibull Coefficients C,K of west wind are 3.97(C),1.98(K). |
