Tidal oscillations in Mars's atmosphere



Atmospheric tides—global oscillations in pressure, temperature, and wind that are subharmonics of a solar day—mainly affect the upper atmosphere on Earth, but on Mars they tend to have effects throughout the atmosphere. Tidal variations in Mars's atmosphere are mainly introduced by diurnal variations in surface temperature as the planet rotates. The absorption of radiation by aerosols in the atmosphere provides an additional forcing, which complicates the tidal structure.
