Research Description

I study spontaneous atmospheric gravity wave radiation from unsteady vortex motions, such as from jet-front systems, cyclones, and hurricanes, using simplified numerical models. I also study “super rotation” in the atmosphere of Venus using the atmospheric general circulation model for the Earth simulator, AFES-Venus.

Our data assimilation system will be the first to produce reanalysis data for the Venusian atmosphere.
