[PPS05-P04] WAVENUMBER-FREQUENCY SPECTRA OF THE MARS ATMOSPHERE: LOW LATITUDES
Keywords:Mars, atmospheric dynamics, MACDA
However, what has been well investigated are relatively large scale waves with wavenumber 1-3 such as baroclinic wave in the winter hemisphere and planetary wave in middle and high latitudes. Atmospheric waves except for migrating and non-migrating thermal tides have not been reported in low latitudes, although atmospheric waves excited by diabatic heating associated with dust events and water ice clouds are expected to exist. In this study, we calculate wavenumber-frequency spectrum of atmospheric temperature T, zonal and meridional winds U and V, and detect all of resolvable atmospheric waves in low latitudes on Mars.
