基于风廓线雷达检验的WRF风场模拟与风切变预报
WRF wind field simulation and wind shear prediction based on wind profile radar inspection
摘要
Abstract
By employing the WRF numerical model,this study simulates the wind field over Dali Airport and examines the results using wind profile radar observations and aircraft-reported wind shear events at this airport.The results show that:(1)the simulated average wind speed profiles across different seasons exhibit characteristics that are largely consistent with observed wind speeds,and can accurately capture the inflection points of wind speed variations with altitude,and the correlation coefficients of wind speed increase with height,and the correlation coefficients of all the altitude layers pass the 99.9％confidence test.(2)There are notable deviations between the simulated and observed wind direction frequency distributions,and the simulated wind directions of each layer above 600 meters align well with the overall observed patterns,and the prevailing wind direction below 600 m has a larger deviation.(3)The simulations provide reliable reference values for wind speed and direction at altitudes of 1 km and above,particularly in capturing the stronger wind speeds.This exploration can offer a valuable reference for addressing wind shear wind field forecasting challenges at airports in low-latitude,high-altitude plateau regions with intricate topography.关键词
