台风"妮妲"登陆期间沿海输电线路局地风场数值模拟研究
Study on Numerical Simulation of Local Wind Field in Coastal Region with Transmission Lines during the Landfall of Typhoon Nida
摘要
Abstract
Aiming to study the distribution characteristics of local wind fields in coastal region with transmission lines during the landfall of Typhoon Nida,the mesoscale meteorological model WRF and the microscale CFD model WindSim are used to design three simulation schemes,including mesoscale simulation based on WRF,microscale simulation based on WindSim,and mesoscale and microscale coupled simulation based on WRF and WindSim.Numerical simulation experiments are carried out and compared with measured data from LiDAR,so as to valify the applicability and accuracy of the different models.The results show that the WRF-based mesoscale simulation can better reproduce the temporal variation of meteorological fields during the landfall of Typhoon Nida period,and the WindSim-based microscale simulation can better reflect the topographic effects of the wind field at a spatial resolution of 10~100m in a specific wind direction.The mesoscale and microscale coupled simulation based on WRF and WindSim can not only correct the topographic effect bias of WRF alone,but also improve the boundary conditions and atmospheric stability of WindSim alone,and have the ability to simulate the three dimensional wind field with complex terrain during typhoon impact with higher accuracy of simulation results.关键词
