| Research Abstract |
With development of the technology for seismic measurement, seismo-acoustic waves have been often observed in shallow large earthquakes. I developed a numerical method in which we can calculate acoustic modes for a coupled model of the solid earth and atmosphere to explain the observed seismic sounds. The atmosphere however has significant motions(winds) that can affect sound propagation differing from the solid earth. To understand effects of winds on acoustic propagation, I made a code dealing with the effect in the normal mode calculation and calculated seismo-acoustic waves affected by winds.
