The Boussinesq approximation is used to model the "natural" type of this process, in which  fluid motion is generated by density differences due to temperature gradients. Cells of this  process in the atmosphere include the Hadley cell and the polar vortex. One subtype of this  process transports substances using the fluid's bulk motion in a particular direction - that type is  called advection. For 10 points, identify this term that combines advection and diffusion, the type  of energy transfer that occus with the movement of a heated fluid in its namesake currents.
