Abstract: Nonlinear equations describing electrostatic drift waves in a spatially nonuniform plasma with a background shear flow and magnetic shear are derived. Various analytical and numerical solutions in the form of vortex chains, periodic along the plasma flow and localized in the perpendicular direction are found. In plasmas with shear flow and steep density gradient the standard magnetic shear stability of drift waves is severely restricted which makes such systems prone to an instability, and the strongly nonlinear solutions presented here may arise as the final stage in the development of instability of drift waves in such plasma configurations.
