A high-resolution HiRISE camera on board NASA’s MRO orbiter captured a Martian vortex as it formed on the surface of the Red Planet.

These alleged demons are made to lift and spin hot air bags. The air near the soil surface can get warm when it comes in contact with warm soil during the day.
The warm air is less dense and rises through the cold air above it, he explains The University of Arizona at the dedicated HiRISE website.
As the additional air moves inward across the surface to replace the ascending sac, it begins to rotate, driven by Coriolis forces, and forms a rotating air vortex.

When incoming air rises toward his spine, his rotation accelerates like a snowboarder bringing his arms closer to his body.
This air moving faster near the Earth’s surface can cause sand grains to bounce and lift dust that rises easily in the growing vortex. In this way the Dust Demon is born. Photo taken October 30, 2020.

The study of dust vortices is important because it indicates weather conditions such as the direction and speed of the prevailing winds.
They also periodically clean the surface of the dust that is gradually deposited from the atmosphere. This is something that could be very useful for robotic missions on Mars.
