Side boundaries of the spherical 'polar cap', our computational domain, are located at latitudes $\\geq 60^{\\circ}$. Implementing observed low latitude flows as side boundary conditions, we solve the flow equations for a cartesian analog of the polar cap. The key parameter that determines whether there are nodes in the high latitude meridional flow is $\\epsilon=2 \\Omega n \\pi H^2/\\nu$, in which $\\Omega$ is t","authors_text":"Mausumi Dikpati, Peter A.
