From The New York Times:
Q. Could a plan being explored to use wind to produce a third of the power for New York City affect weather systems?
A. The usual objections raised to wind farming involve aesthetic issues, expense, noise and fears of danger to wildlife, and the issue of weather impact from wind farming has not been conclusively studied.
There has been at least one preliminary study of wind farming that suggested the possibility of an adverse effect on local weather systems from a large wind farm with many rotors in one area. But the researchers also suggested that potential problems could be ameliorated by redesigning the rotors to produce less turbulence.
The study, published in October 2004 in The Journal of Geophysical Research, used a hypothetical model of a wind farm much larger than any that had been built: 10,000 turbines, with rotor blades 165 feet long, in a 60-by-60-mile grid in north-central Oklahoma.
