探测环境变化对密云气象站地面风观测的影响
Effect of Observation Environment Change on Surface Wind at Miyun Station
摘要
Abstract
Anstract:Employing the observation surface wind data from Miyun Station and Shangdianzi Station from 1994 to 2013,the wind observation difference between the first stage and the second stage at Miyun Sta-tion is analyzed.The results indicate that the average wind speed of the second stage is reduced by 0 .5 m ·s-1 compared to the winds in the first stage.The environment around the station affected the annual average wind speed significantly in 2013.The seasonal and monthly wind speeds are affected by the obsta-cles around the station at different degrees.The maximum attenuation is in spring and March,while the minimum attenuation is in summer and August.The surrounding environment has the greatest impact on the WSW wind velocity and also on the wind speed frequency between 1 m·s-1 and 2 m·s-1 .Comparing the first stage,the static wind frequency in the second stage increases by 5 .5%,and the frequency of static wind has increased at each season.The most obvious increase is in winter and minimum increase is in spring.The increase in fall is greater than in summer.关键词
