My hobby is gliding. The wind forecasts generally give out are for
ground level. A couple of hundred feet up they are quite different
both in force and direction.

The wind forecasts given out in the mass media are for ground level.
As you say the wind is different higher up, which is one of the
reasons why larger wind turbines are being built. Like other
utilities wind operators pay for more detailed and more specific
forecasts, which relate to their work.
