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

Abstract

Our objectives are to build a compatible set of models which 1) calculate the atmospheric GWs excited by an ocean 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 at altitudes of z=200-300 km. These perturbations will then be given to Dr. Makela to calculate the 630 nm airglow response to these GWs.
