Aeolus: "Horns Rev 1 wake effects. Photographer Christian Steiness. The above photograph shows the turbulence field behind the Horns Rev 1 offshore wind turbines. Unique meteorological conditions on 12 February 2008 at 1300 hours resulted in the wind turbines creating condensation (i.e. clouds) of the very humid air, thus making it possible to see the turbulence pattern behind the wind turbines."
