This chapter deals with the underlying mathematics of atmospheric waves. Gravity waves occur between any stable layers of fluids that differ in density. When the fluid boundary is disturbed, buoyancy forces try to restore the equilibrium. The fluid returns to its original shape and overshoots before oscillations finally set in that propagate as waves ...

Submillimeter wave spectroscopy of the atmosphere
Journal of the Optical Society of America, 1976The paper which will be read at this conference will be a review paper in the sense that it will discuss recent and current research in submillimetre atmospheric spectroscopy within an historical framework. This Digest is intended as a guide to the topics which will be considered in the paper.

Nonlinear waves in the solar atmosphere
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2005In this paper, we give a brief review of the contemporary theory of nonlinear waves in the solar atmosphere. The choice of topics reflects personal interests of the author. Historically the theory of nonlinear waves was first applied to the solar atmosphere to explain the chromospheric and coronal heating.

In the previous chapters, we have already found wavelike dynamical manifestations in the atmosphere such as Rossby waves. These waves are a consequence of the conservation of absolute vorticity in the sense that we have considered the effect of Earth’s rotation but not the presence of gravity.

Gravity waves in the atmosphere
Archiv für Meteorologie, Geophysik und Bioklimatologie Serie A, 1951Mathematical discussion is restricted to gravity waves of period short enough for the earth's rotation to be neglected, propagated horizontally through air whose horizontal velocity and static stability vary with height in the layers near the ground.

Atmospheric waves and the ionosphere
Contemporary Physics, 1972A review of evidence supporting the existence of atmospheric waves is presented, and a simple, theoretical approach for describing them is shown. Suggestions for gravity wave sources include equatorial and auroral electrojet, auroral and polar substorm heating, atmospheric jet streams, and large oceanic tides.

AbstractIn an isothermal windless atmosphere Lamb's wave, the energy of which decays exponentially with height, propagates non‐dispersively with the speed of sound. In the real atmosphere the speed of sound and the wind speed vary with height, but it is known that an edge wave similar to Lamb's wave is still possible.

On the atmospheric interfacial waves
Physics of Fluids, 2000We consider waves at the interface of a two-layer fluid. The upper layer is assumed to be isothermal and compressible with a density profile decreasing exponentially with height up to infinity. The lower layer is assumed to be incompressible with constant density bounded below by a rigid bottom with an obstruction of compact support.
