| Zusammenfassung |
| The response of a simplified global
atmospheric circulation model (PUMA) to
spatiotemporal stochastic forcing is analyzed using the statistical
measures originally developed for ensemble forecast evaluation. The
nontrivial effects of time and length correlations of the
stochastic forcing on the ensemble scores (e.g. spread and 'error')
are studied. A maximum for these scores is observed to occur for specific
values of the correlation time. The effects of multiplicative and
additive contributions of the correlated noise are analyzed in
terms of the noise and PUMA parameters. |
