Abstract: The study used a magnetized, inhomogeneous, collisionless, two-temperature electron plasma with shear flow parallel to the ambient magnetic field B=B0ẑ to investigate nonlinear periodic (cnoidal) wave structures created by the coupled drift wave (DW) and electron-acoustic wave (EAW). Satellite observations in auroral regions, the plasma sheet boundary layer, Earth's magnetosphere, and solar wind, as well as laboratory experiments, have identified coexisting hot and cold electron populations. As these electron populations have different temperatures, they are categorized as hot and cold electrons. The hot electrons follow Kappa distribution, while the positive ions stay stationary in the background, and cold electrons have a temperature lower than the hot electrons, i.e., Tc
