A numerical experiment on investigation of the dynamics 
of the interaction of three coaxial vortex rings formed from thermics 
is performed. As a mathematical model of the phenomenon, the system 
of Navier-Stokes equations for a compressible heat-conducting 
gas in a cylindrical coordinate system is chosen. The calculations 
are performed using a finite-difference method based on an explicit 
three-step scheme of splitting by physical processes. The influence 
of the position of the thermics on the common axis of symmetry on 
the character of their motion and interaction is investigated.
