Abstract

Ultra-long waves in the modified Burger model are studied by using the method of travelling-wave solution. Taylor series expansion is used to isolate the characteristics of linear waves and identify the nonlinear waves. The analytical solutions to nonlinear ultra-long waves with the complete Coriolis force and heating,which can be approximately described by the KdV equation and the combined KdV and mKdV (KdV-mKdV) equation,are obtained. The cnoidal waves,solitary waves,and soliton-like solutions are also obtained.
