Observation and Modeling of Tsunami-Generated Gravity Waves in the Earth's Upper Atmosphere

Abstract

To determine the response of the 630 nm airglow in the thermosphere to gravity waves excited by ocean tsunami. To build a compatible set of models which: (1) calculate the atmospheric gravity waves (GWs) excited by a tsunami, (2) propagate these GWs into the thermosphere, and (3) reconstruct the GW field in the thermosphere (e.g., neutral wind, density and temperature perturbations caused by the GWs) as a function of space and time. These perturbations will then be given to Dr. Makela's group in order to calculate the 630 nm airglow response to these GWs.
