Wind Shear Overestimated (2009-03-10)

[Old Forum Archivist]

I did simulation on field with hills and forest. The anemometer data are measured at 40 m. The estrapolated wind speed at 85 m is overestimated. Why do WAsP overstimate the speed? Can I correct the wind shear only changing roughness or height of displacement? Is it a WAsP limit?

The wind profile depends on the quality of your elevation and roughness descriptions, and the exact prediction also on the quality of your data. In addition, the heat flux settings will influence the profile. Without looking at your project in some detail, it would be difficult to say something sensible about the predicted wind shear - including whether it is too large.
