Description:
The flow associated with the sublimation and condensation of carbon dioxide ice in the polar regions of Mars is an important part of the general circulation. However, so far the pattern of the flow is generally not well known. In this study, a Mars general circulation model (MarsWRF) has been applied to derive the pattern of this flow based on some specially designed experiments. The results suggest that the equatorward sublimation and the poleward condensation flows in both hemispheres are rather shallow except near the poles, and the strength of the sublimation flow is significantly stronger than the condensation flow in both hemispheres. The results also show that the strength of the sublimation and condensation flow in the southern hemisphere is much stronger than that in the northern hemisphere. During the summer time, the surface wind in the high-latitude region near the pole could be dominated by the sublimation flow.
