The problem is reduced to a Matrix-Floquet problem, which is solved numerically to determine the stability characteristics. The Coriolis force and the buoyancy force suppress the subharmonic elliptical instability of cyclonic and weak anticyclonic vortices, whereas enhances that of strong anticyclonic vortices. The fundamental and superharmonic instability modes occur, in addition. They are due to higher-order resonance. The growth rate of each instability shows complicated dependence on the parameters N(the normalized Brunt-Vaisala frequency) and R(sub O)(the Rossby number: defined inversely as usual), it their values are small. It decrease as the background rotation rate becomes larger and as the stratification becomes stronger. The instability mode whose order of resonance is less than Min(N,2(1 + R(sub O)))is
