摘要:

本文用振荡理论的方法分析了声重力波在层结等温大气中的传播。结果表明,大气中的AGW可以看作是一个发生在两个本征频率的振荡过程。这种考虑使得解释AGW的一些观察到的特性成为可能。扰动水动力速度随时间和频谱特性的解决方案,获得了一个真正的,但不是复杂的,变量。

英文摘要:

The propagation of acoustic-gravity waves (AGWs) in the stratified isothermal atmosphere is analyzed using methods of the oscillation theory. It is shown that AGW in the atmosphere can be considered as an oscillatory process occurring at two eigenfrequencies. This consideration makes it possible to explain some of the observed properties of AGWs. The solutions for perturbed hydrodynamic velocity versus time and spectral characteristics are obtained in a real, but not complex, variables.
