近年来，美国的风电行业经历了容量的快速扩张，预计这种快速增长将在未来持续下去。在将风的动能转化为电能的同时，风力涡轮机改变了表面-大气交换以及大气中能量、动量、质量和水分的转移。这些变化如果在空间上足够大，可能会对当地到区域的天气和气候产生明显的影响。在这里，我们提出的观测证据，这种影响的基础上分析的卫星数据在2003-2011年期间在中西部德克萨斯州，其中四个世界上最大的风电场所在的地区。我们的研究结果显示，相对于附近的非风电场地区，风电场每十年的变暖趋势高达0.72 °C，特别是在夜间。我们将这种变暖主要归因于风力发电场，因为其空间模式和幅度与风力涡轮机的地理分布非常匹配。
The wind industry in the United States has experienced a remarkably rapid expansion of capacity in recent years and this fast growth is expected to continue in the future,,. While converting wind’s kinetic energy into electricity, wind turbines modify surface–atmosphere exchanges and the transfer of energy, momentum, mass and moisture within the atmosphere,,. These changes, if spatially large enough, may have noticeable impacts on local to regional weather and climate. Here we present observational evidence for such impacts based on analyses of satellite data for the period of 2003–2011 over a region in west-central Texas, where four of the world’s largest wind farms are located. Our results show a significant warming trend of up to 0.72 °C per decade, particularly at night-time, over wind farms relative to nearby non-wind-farm regions. We attribute this warming primarily to wind farms as its spatial pattern and magnitude couples very well with the geographic distribution of wind turbines.
