@korina Yes I'm looking to the surface conditions. I fly paragliders wind at surface/low level is critical for us.
The location is in the Netherlands, where most ground is at sea-level.

After your reply I noticed that the Sounding diagram starts at 200m elevation
Which isn't clearly stated.
99.99% of the Netherlands is below 200m elevation.

Can you clarify why the diagram starts at 200m elevation even for lower locations?

Is just a representation issue or doesn't the model have data below 200m?

The bar at the rigth in the sounding forecast predict much higher windspeeds then wat is shown on the map. Error factor = 3x times the normalized windspeed and windgusts about 1.5-2x times
