Vortex scaling is so neat. At larger scales with a high Rayleigh number, a vortex forms easily. That's the point where all heat transport in the air and water is convection, which is just shedding heat with turbulence. At this point, there is almost no heat transport by radiation, it is tens and tens times greater with convection. This is the final 'super point' where the carbon hypothesis fails.

Hey Geo
Okay before I start the video I looked up Rayleigh number
- describes the relationship between buoyancy and viscosity within a fluid
-Rayleigh number, Ra, is a dimensionless term used in the calculation of natural convection
let's see which definition fits?
Here I go!
