Wind 10 meters above the ground
This chart displays the modeled average wind vector in 10 m above the
ground for every grid point of the model (ca. every 80 km). In general, the
actual observed wind velocity at 10 m above ground is a little bit
lower than the modeled one. However, usually the computed wind velocity
is pretty close to the reality. Therefore this chart is very useful for sailors,
gliders, hang gliders and balloon pilots. (wind-converter)
