The generation of a vortex ring due to a rising atmospheric thermal (light cloud) in the earth gravity field is studied numerically. 3D simulations were carried out with the EGAK code. Results of these simulations are compared with the approximate analytical solutions for the motion of a buoyant vortex ring verified using the existing experimental data.

Keywords: buoyant volume, field of gravity, vortex ring, turbulence, numerical simulation.
