| Zusammenfassung |
In the period between late spring and early summer as well as in
autumn, the Mediterranean is often affected by rapid development of
intense convective systems. In some cases the operational NWP models
are able to provide good indication of occurrence of such severe
weather events (potential instability conditions) but often location
and intensity of convective precipitation are poorly forecasted.
The approach of "PV-thinking" revealed itself as a good tool to
identify favorable conditions for triggering such systems, partially
filling this lack of information and supporting meteorologists in
the very short range weather forecast. Moreover, the advanced use of
data provided by SEVIRI channels onboard MSG satellite, makes
possible an effective application of the PV approach, improving
forecast skill also in areas where local effects are not well
described by the models and/or by the data assimilation. The aim of
this work is to show how the application of the MSG tools together
with the PV philosophy helps in the diagnosis and nowcasting of
intense thunderstorms triggered by tropopause, with particular
attention to a case of intense convection over northwestern Italy
during spring 2005. |
