If so, how? > The answer has to do with turbulence. Flows such a volcano or a billowing smoke stack are necessarily turbulent and will manifest an "infinite" cascade of eddy currents from the very large to the very small. A small scale model of the above, however, will only manifest the larger eddy currents. The smaller eddies will be absent. The difference in the visible flow appearance should be quite plain to the eye.
