With the rapid development of wind power generation， the impact of the construction and operation of utility-scale wind farms on the local climate has attracted extensive attention.In order to study the characteristics of the local climatic response to the deployment of wind farms under different surface conditions， the area from Wulan Chaka to Gonghe Shazhu Yuxiang， which is located in the southwest of Qinghai Lake， was chosen as center， and the mesoscale meteorological numerical model WRF （Weather Research and Forecasting Model） and the Fitch wind turbine model were carried out under the conditions of flat canyons， high-altitude mountains and water body， respectively.The results showed that： Under the ideal situation of the same installed capacity， the averaged wind speed inside the wind farms showed the significant decrease trends under the three sensitivity experiments， and the amplitude and scope of wind speed attenuation was stronger during nighttime than that during the daytime， and the wind speed attenuation in the vertical direction can reached up to 600 m.The 2 m temperature inside the wind farms located in flat canyons or water body mainly decreased， which was possibly related to the negative temperature gradient and the water evaporation enhancement， and the temperature cooling was more significant during nighttime while no significant changes in 2 m temperature were detected over the mountain wind farm.Meanwhile， the changes of 2 m humidity inside the wind farms were not obvious， and the overall decreased trends were mainly weak during nighttime.Due to rotation of the wind turbine， the planetary boundary layer height increased significantly.The characteristics of the local climatic response to the deployment of wind farms under different surface conditions were different， which was mainly related to the different climatic features under different surface conditions， and was also affected by the spatial layout of wind turbines.These results can provide some support for the design of climate-friendly wind farms. |
