Simple Differential Rotation.

Constant Parameters:

• Diffusivity Constant:        0.1  x  10^12  cm^2  s^(-1)
• Alpha Constant:                10  m  s^(-1)
• Meridional Flow Speed:   10  m  s^(-1)

• The shear increases with increasing rotational speed (decreasing equatorial period)

• Cycle amplitude increases with increasing rotational speed.

• Cycle does not depend on rotational speed

• Cycle amplitude increases as shear increases.

• Cycle period does not depend on shear.
