The study concerns self-similar structures that emerge during the process of the thermal vortex ring formation. A qualitative explanation of their origin is provided based on the repetitive Kelvin– Helmholtz instability in multiple scales. This phenomenon is found to invert the turbulent energy cascade near the buoyancy interface. To quantify the associated mixing, the fractal dimension of the interface is also computed
