Utility-scale large wind farms are rapidly growing in size and numbers all over the world. Data from a meteorological field campaign show that such wind farms can significantly affect near-surface air temperatures. These effects result from enhanced vertical mixing due to turbulence generated by wind turbine rotors. The impacts of wind farms on local weather can be minimized by changing rotor design or by siting wind farms in regions with high natural turbulence. Using a 25-y-long climate dataset, we identified such regions in the world. Many of these regions, such as the Midwest and Great Plains in the United States, are also rich in wind resources, making them ideal candidates for low-impact wind farms.
大型风力发电场的规模和数量在全球范围内迅速增长。气象实地考察数据表明，此类风电场会显著影响近地面空气温度。这种影响是由风力涡轮机转子产生的湍流引起的垂直混合增强所致。通过改变转子设计或在自然湍流较强的地区选址，可以将风电场对当地天气的影响降到最低。我们使用了长达 25 年的气候数据集来确定全球范围内的此类区域。其中许多区域，如美国中西部和大平原地区，风力资源丰富，是低影响风力发电场的理想选址。
