If the [[wind]] is [[geostrophic]], the vertical shear is given by the [[thermal wind equation]]. The wind shear at a point is said to be [[cyclonic]] or [[anticyclonic]] according to whether the sense of rotation from the wind vector to the [[shear vector]] at that point is cyclonic or anticyclonic.</div><br/> </div>
