Modeling the Martian seasonal water cycle

Abstract: Abstract. Ever since the observations of Percival Lowell, the annual cycle of Martian water has been a fascinating topic in planetary exploration. Observations by the Viking Orbiter, supplemented by Earth-based microwave and infrared observations, have given us a reasonable picture of this cycle. We are now also able to model the cycle using our Mars Climate Model, a simplified atmospheric general circulation model designed specifically for this purpose. We find that a thin adsorbing layer of the Martian regol… Show more

“…Mars also has a strong seasonal H 2 O cycle by which water is exchanged between the surface and the atmosphere through various processes, and then redistributed in the atmosphere by atmospheric circulations (Jakosky and Farmer 1982;Jakosky 1985;Jakosky and Haberle 1992;Houben et al 1997;Richardson and Wilson 2002;Mischna et al 2003). Seasonal water reservoirs include water ice on or within the seasonal or residual polar caps, surface or subsurface ice in high-latitude regions, physically adsorbed and chemically-bound water within the near-surface regolith, and possibly surface and subsurface liquid water in the form of liquid saline solutions (brine) (Jakosky 1985).…”

“…Models have been developed to study the adsorption of water onto regolith grains (Zent et al (1993); Zent and Quinn (1997); Houben et al (1997)). In particular Zent et al (1993) used a basalt regolith model to show that daily 'breathing" of the regolith altered the column water vapor abundance by ∌ 1 pr-ÎŒ m. But different materials could introduce a stronger effect.…”

“…Richardson and Wilson (2002) suggest that the difference in elevation between the two caps influences H 2 O deposition, with the NPLD being favored under current conditions. Water ice that sublimates as the seasonal CO 2 retreats from the north pole is hypothesized to be driven poleward by baroclinic eddies ("vacuuming effect"), resulting in accumulation at the highest latitudes (Houben et al, 1997;Bass et al, 2000). Deposition of dust and ice may also be influenced by the effect of mid-latitude topography on atmospheric circulation.…”
