A wind turbine includes a laser wind velocity measurement system mounted on a nacelle of the wind turbine for determination of air velocities at the same relative position in front of the wind turbine, and which compensates for wind velocity changes prior to impingement of the air flow on the adjustable pitch wind turbine blades so that desired maximum tip speeds, tip speed ratios, and normalized power output C.sub.p may be maintained.

[ What is claimed is:] [1.]1. A wind turbine, comprising:a nacelle; anda wind velocity measurement system which determines air velocities at a relative position in front of the wind turbine, said wind velocity measurement system including a laser anemometry system for emission of a laser light beam for illumination of particles in the air,wherein the laser anemometry system is mounted on the nacelle to follow the motion of the nacelle so that the determination of the air velocity in front of the wind turbine is accomplished at a same relative position with respect to the nacelle.
