Mars - Antarctica Connection

As the atmosphere of Mars is cold and thin, water-ice clouds can form despite the limited amount of water vapour compared to Earth.But until now, it had been thought that any snow precipitation that fell from these clouds did so as slowly settling particles, rather than in rapid storms.

A recent atmospheric model, however, revealed that the cooling of water-ice cloud particles during the cold Martian night can create unstable conditions within the cloud, triggering a descending plume of snow.

These turbulent storms, which can only form at night, act to vigorously mix the atmosphere and, in some places, deposit snow on the surface
