Hi, I 've had the same issue sometimes very amplified due to site particularities. It is not however clear to me if those deviations have an impact on final energy yield figures or just mix the mean wind speeds intra-bins and overall. Thanks, Nick

I also encountered this problem in one project. WAsP self prediction of a mast fails by 0,1 in average wind speed (all sectors), and sectorwise results are terrible (deviations of up to 1m/s) particularly in sectors with few data. The widrose is distorted. I wonder if this is an issue of WAsP limitation of capabilities or there is something wrong with the project model. Any opinions, experiences ? Terrain is rough. Thanks, Nick
