Rough
I launched off mount leinster and flew off towards the coast deciding that there should be a nice thermal source from the next hill with a turbine on top. The turbulence was so bad that I immediately headed to Bunclody, landed then spent the next couple of hours on a perfectly good soaring day sitting in the sun and drinking Guinness.
The turbulence from the turbines has had a documented effect on crop growing times by raising the average air temperatures.
