Given this, it would be sensible to conclude that thermal energy would be convected transported away from the equator and towards the poles. As such, the concept of the "Hadley Cell" is introduced, as is visible in Figure 1.3. At its root a horizontal circulation that serves as a "conveyer conveyor belt" for thermal energy, significant differences in the cell's behavior can be expected depending on whether or not the fluid is laminar or turbulent.
