Study: Wind farms affect local surface temperatures

Study: Wind farms affect local surface temperatures. So Global Warming is all because of wind farms, Anthony? Good one. Actually the University of Illinois press release Anthony Watts found quantifies a slight local daytime cooling and nighttime warming due to wind turbines vertically mixing air layers.

Anthony finds the paper especially “interesting” because the late Dr. Steven Schneider, a dedicated opponent of climate change denialism, edited it. Why so interesting Anthony? Should Dr. Schneider have “re-framed” the paper to match his manipulative “post-normal” purpose? Maybe Anthony’s surprised that a scientist could simply follow the facts. It doesn’t happen much on his side of the fence.

  1. So is there a net effect from the wind farms? If you get cooling during the day and warming at night do they cancel each other out cumulatively?

    On the other hand, has anyone ever done a study on the local climate around, say, coal power plants? I bet they are just *great* for the local climate. But Anthony doesn’t really care about that, does he?

  2. Mark S………. Reading many variations on the same press release indicatess that only one would apply in any given area. And I saw no mention of daytime cooling considerations.
    Presumably the resulting revenues would cover nearby crop damage. I’d guess the real concern is (miles?) downwind – which will be addressed in a future paper. And which explains the search for areas with already turbulent winds.
    Any really negative effects would have already been noticed around existing wind farms. This study may be just an effort to understand what’s happening (‘science’). Without any dire expectations.

    CONFUSING………. What was Anthony thinking? The orchard fans he mentioned are too obviously for still (windless!) nights. For corroboration, just consider the smudge pot alternative, which is also meant to increase air circulation.


    “Turbulence creates stronger mixing of heat and moisture, which causes the land surface to become warmer and drier,” Baidya Roy said. “This change in local hydrometeorological conditions can affect the growth of crops within the wind farm.”
