我国大别山区风电场群对局地气候影响研究初探——以湖北大悟为例
A Preliminary Exploration on the Influence of Wind Farms on Local Climate in Dabie Mountainous Areas in China: A Case Study of Dawu in Hubei Province
中文摘要：
选取大悟县风电场群及其周边地区3个气象站1993—2016年气温、风速、降水观测资料，采用可能受影响区和非受影响区气温差值、风速比值、降水比值法，分别对风电场群建设前后的各气象要素进行了对比分析，讨论了大悟县风电场群对当地气温、风速、降水的可能影响。结果表明：风电场群建设和运行对大悟县局地气温和风速有一定影响，其中气温明显上升，风速有所减小，但其影响程度小于年代际变化，降水量则未见显著影响。由于大悟县风电场群建成时间较短，且气象站的观测受到多种因素的影响，因此风电场群运行造成的局地气候效应有待更长时间观测统计分析及更多研究方法的验证。

Abstract：
Data of observed temperature, wind speed and precipitation from three meteorological stations in and around the Dawu wind farms from 1993 to 2016 were selected, and the temperature, wind speed and precipitation changes since the wind farms started producing energy were analyzed. The temperature, wind speed and precipitation before wind farms were operational were compared with those same factors after the wind farm became operational. The effect of the wind farm operations on regional climate was analyzed by temperature difference, wind speed ration, and precipitation ration between areas affected and unaffected by wind farm operation.The analysis showed that the local climate changed as a result of running the Dawu wind farms: temperature increasedand wind speed decreased. However, the degree of influence is less than natural interdecadal variation in climate, and the wind farm operation had no signifcant effects on precipitation. Because the wind farms have only been operational for a short period of time, and observations from meteorological stations are subject to the impact of many factors, the local climatic effect caused by the construction of wind farms needs to be verifed with observation statistics and analysis over a longer time.
