This research suggests that wind farms could be located much nearer to existing installations than prior modelling studies have indicated. Our observations suggest that 2 km away, the natural background variability of the planetary boundary is greater than the signal from the wind farm. However, wind farms do tend to increase night-time near-surface temperatures by 1–2°C, with potentially important agricultural implications for groups of wind turbines collocated with soy and corn crops in the Midwest.
