• Topological strtncttrre and reconnection of' uaaagnetic fltrx lines are investigarted by analyzing thentrnaerical soltrtion of the Botrssinesq raa?tgneto-h)'drodynaunic equations in a rotatung sphericalshell. Five pairs of Taylor-Proudnaan vortex COIUIIIIIIS are gener?tted and drift westward ste?tdily.Magnetic field is intensified around the tops of' these xxortex COILIIIIIIS. lN'Iagnetic flux lines connecteast-w'est ?xd.jacent dotnains of intense tnagnetic field, which rtaigrate eastxvard relative to thevortex coltrnans. XX7e describe the variation of' topology of zaaagnetic fltrx lines associaxted withthis eastward tnigration.
