| Zusammenfassung |
| In this paper, we
show that the behaviour of weakly nonlinear waves in a 2-layer model of
baroclinic instability on an f-plane with varying viscosity is determined
by a single, degenerate codimension three bifurcation. In the process, we
show how previous studies, using the method of multiple scales to derive
evolution equations for the slowly varying amplitude of the growing wave,
arise as special limits of the general evolution description. A companion
study will extend the results to a β-plane. |
