The influence of wind on the pointing accuracy of large aperture radio telescopes is becoming increasingly serious, especially at high observing frequency. Obtaining the wind field characteristics efficiently is very important to reduce the wind disturbance on antenna structure. In this paper, an error evaluation of numerical simulation method is established based on the measured data of single point wind tower, and the wind field characteristics are obtained from the evaluated numerical simulation results combined with the measured data for the 110 m aperture QiTai radio Telescope (QTT) site. According to the simulation results, compared with the measured data, the root mean square error (RMSE) of wind speed is less than 1 m s⁻¹, and the minimum wind speed RMSE is 0.2 m s⁻¹. An analysis of the wind field characteristics of the QTT site suggests that the active wind resistance design of the antenna periphery should focus on the SSW (south-south-west) direction.

风对大口径射电望远镜指向精度的影响越来越严重，特别是在高观测频率下。有效获取风场特性对于减少风对天线结构的干扰非常重要。本文基于单点风塔实测数据建立数值模拟误差评价方法，将评价数值模拟结果结合110 m口径齐台射电望远镜实测数据得到风场特性。 (QTT) 网站。根据仿真结果，与实测数据相比，风速均方根误差（RMSE）小于1 ms ^-1，最小风速RMSE为0.2 ms ^-1. 对QTT站点风场特性的分析表明，天线外围的主动抗风设计应侧重于SSW（南-南-西）方向。
