This article reports that wind farms can change the weather. According to a model of how these forests of giant turbines interact with the local atmosphere. Somnath Baidya Roy from Princeton University, and his colleagues modeled a hypothetical wind farm consisting of a 100 by 100 array of wind turbines, each 100 meters tall and set 1 kilometer apart. They placed the farm in the Great Plains region of the U.S. an area suitable for large wind farms, and modeled the climate using data from Oklahoma. At 3 am the average wind speed in Oklahoma is 3.5 meters per second, but it increased to around 5 m/s in the model wind farm. Neil Kelley, a meteorologist at the National Renewable Energy Laboratory in Golden, Colorado, has gathered data from a wind farm in California.
