Abstract:
The generation and propagation of acoustic gravity waves (AGWs) in a two-dimensional Earth atmosphere was numerically simulated on the basis of a magnetohydrodynamic model. Due to the divergent form of the equations and the conservativeness of the numerical method, strong perturbations, including discontinuous solutions, were considered and computed by applying a shock capturing algorithm. The results were compared with previous ones obtained using the Euler equations. The comparison results confirmed the generation of atmospheric AGWs by pulsed ground-based sources and supported the possibility of using simpler gasdynamic models for the given class of problems in a fairly wide range of governing parameters.
Key words:
MHD-based simulation of ionospheric perturbations, hyperbolic equations, conservative numerical method, numerical solution of the Euler equations.
