| Zusammenfassung |
| This study analyses the extreme event which took place on 4 November 1966,
when a storm produced intense and persistent precipitation over northern and
central Italy and an extreme surge in the northern Adriatic Sea, causing
casualties and huge damages. Numerical simulations with a regional
atmospheric model have been performed to reconstruct the phenomenology of the
event. Results have been compared with observations. This study shows that
the choice of the global fields for initial and boundary conditions is
crucial for the quality of the reconstruction. The simulation is reasonably
accurate if they are extracted from the NCEP re-analysis, while it is not
satisfactory if ERA-40 data are used, though fields have a higher resolution
in the ERA-40 than in the NCEP set of data. The internal physics of the model
plays a smaller role in the reproduction of the dynamics of the event. |
