In Quantum Theory that makes sense.

Your sudden invocation of quantum theory doesn't make any sense to me. At
no point does one need to utilize the Schrodinger, Dirac, or Klein-Gordon
equations or any of their related equations in order to model or understand
the onset of turbulence.

Warmer atmospheric gas has a greater photon
exchange rate and that creates repulsion, that of course
is why a heated closed volume increases in pressure.
We may term that as "anti-viscosity", where viscosity
is similiar to "stickiness".

In brief, *warm things repel warm things* better than
*cold things repel colds things*, all other things being
equal.
