| Zusammenfassung |
| The Valencia region, on the Mediterranean coast of the Iberian Peninsula, is
propitious to heavy precipitation, especially the area encompassing the South
of Valencia province and the North of the Alicante province. In October 2007
a torrential rain affected the aforementioned area, producing accumulated
rainfall values greater than 400 mm in less than 24 h and flash-floods that
caused extensive economic losses and human casualties. This rain event has
been studied in numerical experiments using the Regional Atmospheric Modeling
System. The present paper deals with the effect of
using the different convective parameterizations (CP) currently implemented in the
Regional Atmospheric Modeling System (Kuo and Kain-Fritsch) in the forecast results, in particular on
precipitation forecast. Sensitivity tests have been run with and without
these parameterizations activated in a series of combinations of the
different grids. Results are very different depending on the model convective
parameterization setting. A statistical verification has also been undertaken
by calculating different skill scores for each simulation in the experiment. |
