Forced Stationary Planetary Waves in Mars's Winter Atmosphere

摘要: Abstract Mariner 9 and Viking spacecraft observations provided evidence for planetary-scale, wavelike disturbances in the Mars winter atmosphere. Possible sources of wave activity are dynamical instabilities, example, barotropic / or baroclinic instabilities. Other candidate forced. quasi-stationary planetary waves—waves that arise predominantly via zonally asymmetric surface properties. The authors attempt to model aspects activity, focusing on forced waves representative wintertime atmospheres Mars, by applying a spherical linear primitive equations model. Basic states representing relatively “nondusty” “highly dusty” conditions near solstice allow wavenumber 1 2 propagate meridionally vertically about jet. Higher wavenumbers strongly trapped. Stationary during northern southern extratropics differ amplitude, phase, dominant horizontal pattern. Northern ...
