Stationary vortex solutions of the Charney-Hasegawa-Mima equation describingplanetary Rossby waves and plasma drift waves are analyzed for background flowwith velocity shear. The solutions are obtained by Larichev-Reznik's method thatdivides the entire plane into two regions by a circle on which the internal and externalsolutions of linear equations are connected. The boundary conditions on the circleare satisfied correctly by adding a vorticity-free flow to the external background shearflow. Explicit flow patterns, dipolar, tripolar and quadrupolar, are given for severalkinds of the background shear flows; the monopolar vortex like the Jovian Red Spotcould not be obtained by this method. Another method is given, to derive a nonlinearequation for the stream function when the equilibrium density profile and shear flowin a plasma are prescribed.
