摘要
提出了一种基于GIS的山地风速模拟的方法。该方法以实际气象台站的观测数据为基础,将其订正到海拔3300m处,并进行克里金插值,以此作为背景风速。参照DEM数据,考虑风速受不同地形的影响,最终得到不同山地地形条件下近地面风速场。结果表明该方法模拟得到的风速场具有较好的精度,能够满足生产应用要求。
This article presents a method of simulating wind speed on mountains based on GIS.On the basis of the observation data of meteorological station,the method revises the data to 3300 mabove sea level and use Kriging interpolation to get a background wind speed of wind field simulation.Under the background of the wind speed and taking the DEM data and different terrain conditions＇ influence on wind speed into consideration,the article gets wind speed field that near surface.The result shows that the wind speed which is got through simulation has a high accuracy,which can satisfy the application demands of the production.
