I have one point as a pyro source emitter and there's no other forces exerted upon it besides buoyancy, so what I would expect to see is a symmetrical mushroom like shape coming about.

Explain, please?

I also did an OpenCL version, resulting in a similar asymmetrical shape of smoke.

So where does this mysterious 'disturbance force' come from?

This is what I can get from DOP pyro solver by bringing in the one point emitter. The smoke is not strictly symmetrical but looks more correct than SOP pyro solver.

But still I don't understand what's hiding behind the scenes!
