Abstract
The stability properties of the equilibria with constant wind shear (both in vertical and horizontal direction) and the non-constant static stability in bounded, inviscid and adiabatic atmosphere were investigated by using normal mode method. The results show that the stability property is determined by Richardson number Ri as well as the absolute vorticity. When the absolute vorticityF is positive, i.e.F > 0, (whereF = f+ −v x ) the sufficient condition for symmetric stability isR i , > f / F and whenF < 0, the equilibria are unstable for all possible normal mode disturbances. In addition, the most unstable growth rate was also obtained here.
