Compressibility effects on the reversed shear Alfvén eigenmode in tokamak plasma are studied numerically. It is shown that compressibility is favorable for the existence of the reversed shear Alfvén eigenmode even without the pressure gradient, and the frequency of the reversed shear Alfvén eigenmode is modified by the geodesic frequency, which is consistent with an analytical theory.
