Previous work on axisymmetric shock solutions in hybrid model flows is extended to the case when the shocks are nonaxisymmetric. The properties of the sonic surface as well as the shocks are characterized analytically. The shocks are assumed to be self-similar, and the flow everywhere is assumed to be in hydrostatic equilibrium in the vertical direction. The shocks are found to be formed for two different states of the fluid: a high state, when the rotational velocity is much larger compared to the radial velocity, and a low state, when the radial velocity is much larger compared to the rotational velocity. Examples of these shocks are provided. 9 refs.
