| Zusammenfassung |
| Storm surge events occur
in the Adriatic Sea,
in particular during autumn and winter,
often producing flooding in Venice.
Sea levels are forecasted by numerical models, which require wind
and pressure fields as input. Their performances depend crucially on the quality of those fields.
The storm surge event on 16 November 2002 is analysed
and simulated through a finite element hydrodynamic model
of the Mediterranean Sea.
Several runs were carried out, imposing different atmospheric forcings:
wind fields from ECMWF
analysis, high resolution winds from the limited area model LAMI
and satellite observed winds from QuikSCAT (NASA).
The performance of the hydrodynamic model in each case has been quantified.
ECMWF fields are effective in reproducing the sea level in the northern
Adriatic Sea, if the wind speed is enhanced by a suitable multiplying
factor. High resolution winds from LAMI give promising results,
permitting an accurate simulation of the sea level maxima.
QuikSCAT satellite wind fields produce also encouraging results
which claim, however, for further research. |
