Abstract: 
We investigate the excitation of meridional flow by the differential rotation of the Earth's liquid core. The excitation mechanism is based on the hypothesis about the primary role of the differential rotation of the inner core and mantle. For cylindrical and spherical liquid layers confined between two rotating axially symmetric shells, the conditions for the azimuth flow instability which creates a meridional component were obtained. Methods were proposed for the solution of nonlinear equations describing steady flows at large Reynolds numbers.
Keywords: differential rotation, excitation mechanism, nonlinear equations
