On the Question of Calculating the Parameters of Vortices in the Near-Surface Atmosphere of Mars

详细

The paper is dedicated to the study of dust vortices on the Earth and Mars. The hydrodynamic similarity of convective vortices is considered, and the similarity criteria are determined. The motion of dust particles in a vortex is modeled. The conditions for the similarity of dust particle trajectories in a vortex in the terrestrial and Martian atmospheres are determined. It is shown that there is a similarity between terrestrial and Martian vortices. This fact can be useful for the study of the Martian atmosphere, given that there are proven methods for measuring the parameters of vortices on the Earth, while such measurements on Mars are difficult.
