Orographic Model Display
As a suggestion to improve the readability of your charrts in orographic terrain e.g. the alps, you could filter out the color display if a wind value lies "inside" a mountain. See here:
The visibility of the Föhn (Sout-North-Wind in the valleys) would be much more distinctive.
You can change yourself the color scale of Wind.
Go to Settings -> Customize color scale.

BTW this color scale showing wind speed has nothing to do with the Orographic Model which is the way how the Weather Model is smoothing the terrain.
