| Zusammenfassung |
| MSG satellite images of 30 October 2008 show the development over north-central Italy of
several rain bands and multiple wave-trains during a strong south-easterly wind episode
associated with a deepening synoptic trough and cold front passage. The event was studied by
means of the ISAC model chain constituted of the hydrostatic model BOLAM and the nested
non-hydrostatic model MOLOCH at 1 kilometre resolution. Diagnostics of model output was
performed to reveal the physical origin of the dynamical features and precipitation
field as simulated. Based on our results we propose a theoretical framework in
which symmetric instability underlies some of the observed precipitation patterns. |
