[xWind yWind] = Wind2Vxy(upSpec,Atm,[G]);
Rotate components of natural wind transverse to the line of sight from the base coordinate frame to user-specified coordinates. Rotation is based on the angle between the projection of the zenith onto the base coordinate frame in the target plane and the input projection. If the geometry structure is input, the base coordinate frame is the target T/P coordinates in the plane perpendicular to the propagation path. Otherwise, the base coordinate frame is such that the y direction is in the "up" direction and all horizontal components of wind are in the x-direction.
