Cell convection is relatively common. For example, this is why large amateur telescopes perform worse for about an hour after they're brought outside: the mirror is "hot" compared to the air, so a network of toroidal convection cells (spinning doughnuts of air) forms on its surface, ever so slightly messing with the rays of light. There's actually an attractor for some of these networks (speaking in general), where they form hexagonal cells. Of course, in most cases, it's more disorderly than that. I'm not sure how a turbocharged network could form, but I'm looking forward to learn more on this topic.
