Hi, I tried to reproduce the energy yield at a turbine site, using .tab data and a met mast. By doing this, WASP creates a profile with no change of wind speed with height, at all. In some heights it even gets less. The wind data is MERRA - data, so there don't exist any inconsitencies. That the terrain is very complex (RIX around 30 %, orographic speed up: up to 50 %). I have another met mast in the same terrain,around 1 km far, with similar orographic conditions (RIX around 30 %, orographic speed up: even up to 80 %). At that other site the model calculates a "normal" profile, like it usually looks like. Does anybody know whether I've done some stupid mistake? Or is it just the fact that WASP cannot handle steep terrain like that, and as result produces strange profiles? It would be great if you could answere me as soon as possible, because I need to finish some project urgently. Kind regards, Anna
