A simple model of the coupled ocean atmosphere is considered to investigate the role played by nonlinearities in the evolution of large scale instabilities related to ENSO. In this paper we focus on the nonlinear evolution of unstable waves. The initial disturbances develop to finite amplitude on a long space- and time scale and their evolution is governed by amplitude equations of so called complex Ginzburg-Landau type. The coherent structures which emerge show how important the associated space- and time scales are in equatorial dynamics. |
