Theoretical Properties of Omega -Loops in the Convective Zone of the Sun. V. Coriolis Force and the Centrifugal Potential Barrier
The effect of Coriolis force and centrifugal force on a rising sheet of fluid in an otherwise rigidly rotating fluid body (representing an idealized solar convective zone) is treated, showing the minor effect on the Kelvin-Helmholtz instability of the rising sheet. The principal effect is the reduction of the small centrifugal force on an element of fluid responding to the Coriolis force. The result is that a substantially steeper ambient superadiabatic temperature gradient is required if the rising fluid is not to be cut off by the ambient hydrostatic pressure. This result suggests the theoretical possibility that there may be substantial activity of buoyant flux bundles in the lower convective zone that is prevented from showing itself at the visible surface of the Sun.
