Gravity Wave Excitation from Ocean Waves and Tsunamis, and Propagation Via Ray Tracing into the Thermosphere

Abstract:

In this poster, we discuss new solutions which describe the excitation of
acoustic gravity waves from a moving surface ocean wave. We then
describe a new method by which to ray trace the gravity waves into
the thermosphere. We show that the ray traced-solutions equal the
exact Fourier-Laplace solutions in the limit that the winds are zero,
the temperature is constant, and thermospheric dissipation is turned off. 
We then apply these solutions to the gravity waves excited by a moving
ocean wave using realisitic wind, temperature and thermospheric
dissipation. Finally, we apply these results to a recently-observed
tsunami.
