Title: Characteristic Analysis on Surface Wind Field at Xinjin Airport in Sichuan
Abstract: Based on the observational surface wind data at Xinjin airport in Sichuan Province from January 2005 to February 2010,the diurnal change of seasonal mean,seasonal and annual variation features of surface wind at Xinjin airport are statistically analyzed.The relation between surface instantaneous wind and airport runway is studied and the forecast of surface instantaneous wind with wind velocity ≥5 m·s-1 are explored.The results indicate that the airport are mainly affected by north wind,west wind and southeast wind;the wind velocities of north and southeast winds are the largest;the strong wind mainly appeared in spring.Furthermore,the north wind is common in every season.However,the frequency of north wind appeared common in autumn and winter is far more than that in spring and summer.The wind velocity gradually increases in the morning and reaches the maximum value on the afternoon,and then it begin to gradually decrease at nighttime.Comparing with the daytime,its change is smaller than that at night.Annual mean wind velocity is small with small interannual change,static wind and small wind have high frequency.The surface instantaneous wind with wind velocity ≥5 m·s-1 and lasting for a long time is the forecasting emphasis of the weather system.
