One distinction between the tank experiment and the earth is that while the Coriolis parameter changes at each location of the earth (due to a constantly changing angle phi, or the angle equivalent to the earth's latitude), whereas it remains constant in the tank because the Coriolis parameter remains unchanged. Therefore, in order to simulate the change in regime from a Hadley cell-dominated means of heat transport to one tyrannized by rotating eddies, the rotation rate of the tank must be manually changed. At some threshold of rotation rate, the fluid will transition from being laminar in solid-body rotation to turbulent, resulting in changes in the means of heat transport. 

Theory

We can understand the general circulation of the atmosphere by formulating a general theory of the Hadley Cell and its development and progression.
