Large-scale development of wind farms has not only brought environmental benefits, but it will also affect the local meteorological environment. We chose Zhurihe wind farm, which is located on Sonid Youqi of Inner Mongolia, as our study area. Our observation instrument is the HOBO automatic meteorological station. The observation points are set up in the upwind area, inner wind farm and downwind area. This allows simultaneous observation of land temperature and near-surface air temperature and humidity of 1.5m range of wind farm area and analyze the effect of wind farm on near-surface temperature. The results show that the existence of wind farm would affect temperature and humidity inside and outside of wind farm area. In the daytime (10:00-16:00), there is a cooling and humidifying function in the inner area and downwind area. The relationship of air temperature and land temperature in these three seasons is upwind area>inner wind farm>downwind area. On the contrary, air relative humidity is downwind area >inner wind farm> upwind area, compared with upwind area. This means that the influence of the wind farm on the near surface temperature reduces with the increase in environment air temperature and land temperature while the influence on air relative humidity increases at the same time. The water surface evaporation of 24 hours of the inner wind farm is less than upwind area.
