Fluid motion in the field of vortex pair on a steady sphere. (Ukrainian. English summary) Zbl 1177.76062

Summary: Advection of passive particles in the field of a vortex pair on an irrotational sphere is investigated. A numerical analysis of the solutions is performed. Equations of motion of point vortices in spherical coordinates and in stereographic projection are given. Streamlines in inertial and corotating frames are shown.
