| Zusammenfassung |
| We discuss how a climate dependence can be introduced in objectively tuned empirical parameters in the parameterization of unresolved scales. We apply the fluctuation-dissipation-theorem to predict the change in the statistics of a perturbed climate and use this information to correct the empirical parameters. This approach is tested within the framework of a low-order atmospheric model on the sphere with empirical stochastic closure. |
