运用ArcGIS结合协同克里金法与CFD法对地形风数值模拟研究OA

In order to more accurately estimate the wind speed under complex terrain conditions,ArcGIS combined with kriging method and computational fluid dynamics method to calculate the wind speed in a certain area of the Tianshan Mountains was used to explore the application possibilities of the two in solving practical problems.It is found that the budget results of ArcGIS combined with elevation and kriging interpolation on wind speed are consistent with the law of increasing with altitude,and the results are consistent with certain spatial distribution characteristics,which is suitable for large-scale prediction.The calculation results of the CFD method for local areas are also consistent with the law that the wind speed increases with the increase of altitude,compared with the interpolation method,the calculation results show the influence of microtopography on wind speed and wind direction,and the prediction results are more comprehensive.
