= Critical wind speed for vortex shedding . V. m (z) = Height-dependent average wind velocity . w (z, t) ) = Dynamic component of wind velocity – turbulance. w. max = Maximum turbulance velocity . z. o = Surface friction coefficient . z. min = Minimum height in which surface friction is constant . z. r = Reference height
