- Abstract: Coherent Rossby waves are integral to large-scale atmospheric processes, influencing weather patterns, energy redistribution, and global circulation. This study explores the nonlinear dynamics of these waves by deriving the two-dimensional Nonlinear Schrödinger Equation (2D-NLSE) from the 2D-Charney–Obukhov equation, which describes large-scale motion in a rotating, stratified fluid. The 2D-NLSE emerges as a powerful tool for understanding how weak nonlinearity and dispersion govern the evolution of Rossby wave packets. The 2D-NLSE reveals the influence of nonlinear interactions in shaping Rossby wave evolution, including phenomena such as wave amplitude modulation, soliton formation, and the emergence of localized structures. These nonlinear effects are pivotal for understanding the mechanisms of energy exchange across different scales in atmospheric systems. The analysis reveals that Rossby waves can give rise to the formation of rogue waves, as well as bright and kink-type Rossby wave envelope solitons. The results may contribute to the theoretical understanding of nonlinear wave propagation in geophysical systems and offer a foundation for improving predictive models for atmospheric behavior.
