| Zusammenfassung |
| In this paper we
discuss some theoretical results obtained for climate models (theorems for
the existence of global attractors and inertial manifolds, estimates of
attractor dimension and Lyapunov exponents, symmetry property of Lyapunov
spectrum). We define the conditions for "quasi-regular
behaviour" of a climate system. Under these conditions, the system
behaviour is subject to the Kraichnan fluctuation-dissipation relation.
This fact allows us to solve the problem of determining a system's
sensitivity to small perturbations to an external forcing. The
applicability of the above approach to the analysis of the climate system
sensitivity is verified numerically with the example of the two-layer
quasi-geostrophic atmospheric model. |
