The interaction between zonal flow and Rossby waves with scalar nonlinearity |
|
| Authors: | Zhang Xi-Ping Zhao Qiang |
| Abstract: | The nonlinear interactions between zonal flow and Rossby waves are studied by numerical simulations with focus on the effects of scalar nonlinearity. The numerical results show that the scalar nonlinearity has an appreciable influence on the Rossby dipole evolution and can reduce the threshold of the disturbance energy increase. |
| Keywords: | Rossby wave sheared zonal flow dipole scalar nonlinearity |
