Not all wind shear is turbulent. In fact, if air is not allowed to mix turbulence may be minimal even in the presence of moderate or greater wind shear. Therefore, atmospheric mixing is the primary cause of the turbulence we feel flying in an aircraft. Whether air will mix or not largely depends on the environmental temperature profile. A stable atmosphere inhibits vertical mixing and tends to drive down the risk of significant turbulence. On the other hand, an unstable atmosphere is one that promotes vertical mixing paving the way for moderate or greater turbulence especially in the presence of vertical wind shear. In this workshop, you will learn how to use a Skew-T log (p) diagram to identify the altitudes that may have the highest potential for moderate or greater turbulence.
