Given this, it would be sensible to conclude that thermal energy would be 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, the Hadley cell is a horizontal circulation pattern that serves as a "conveyor belt" for thermal energy, and significant differences in the cell's behavior can be expected depending on whether or not the fluid is laminar or turbulent.
