Abstract

The Mars climate model MarsWRF was run with fully interactive dust parametrization, assuming an infinite surface dust reservoir. Changing the horizontal resolution from 5°×5° to 2°×2° produced different dust cycle variability and dust source regions. The higher spatial resolution allowed for a better representation of the surface topography and associated surface dust lifting by wind stress, that is more consistent with observations. Global Dust Storm Events typically occurred if dust storm activity at northern Hellas Planitia connected with that at southern Chryse Planitia.
