Short summary
We performed high-resolution numerical simulations of nonlinear acoustic-gravity waves (AGWs) at altitudes 0–500km and compared them with analytical polarization relations of linear AGW theory. After some transition time, t > te, the numbers of numerically simulated and analytical pairs of AGW parameters, which are equal to confidence 95%, are larger at altitudes 30-60km and are smaller at t < te. The differences reveal circumstances where numerical simulations of waves are required.
