| Zusammenfassung |
| The understanding of extratropical low frequency variability (LFV) has vital importance to
improve the predictability of weather. Idealized models provide opportunity to explore the
theoretical concepts effectively, and hence can be applied to study the extratopical LFV. The
three layer model of quasi-geostrophic potential vorticity (Marshall and Molteni ,1993) has
been used to explore the long-term predictability. The predictability is measured by the
computation of Lyapunov exponents which provide an indication of the choaticity of the
dynamical system. In this study we present the results for the circulation regimes, lyapunov
exponent spectrum and the attractor dimension from a quasi-geostrophic three layer model. |
