An account is given of theoretical hydrodynamic models for the behavior of vortices with axially varying rotation rates. For purposes of illustration, two flow classes are considered: radically unbounded solid body-type vortices; and vortex cores of finite radius embedded within radially decaying vortex profiles. For the first type of flows, the von Karman-Bodewadt similarity principle is applied and new exact solutions of the nonlinear Euler equations obtained. For the second class of vortex flows, a linear analysis of the Euler equation is employed. This linear solution describes the formation of a central updraft and an annular downdraft ringing the periphery of the vortex core.
