ABSTRACT
Although we will be mostly interested in turbulent conditions, it is instructive to consider weaker solutions near the onset of convection. Without rotation, convection occurs in the form of roll pairs with up-žow and down-žow regions alternating periodically in space. With rotation, bulk convection is suppressed, and the form of the convection is substantially modiŸed into vortical structures such as illustrated in Figure 38.1, where black shading indicates cyclonic (with the rotation direction) circulation and gray shading indicates anticyclonic (counter to the rotation direction) circulation. ›e sense of the rotation of the žow is determined by the action of the Coriolis force on žow that is either converging or diverging
