Some Possible Solutions of Nonlinear Internal Inertial Gravity Wave Equations in the Atmosphere

In this paper, the nonlinear internal inertial gravity wave equation is derived by the analysis method of phase plane and is solved by integration method. The results showed that this nonlinear equation not only has ordinary soli-tary wave solution but also has another extra-ordinary solutions, and the form of solution is related to stratification stability, wave velocity and direction of wave motion.
