| The HYDROPTIMET case studies 9-10/06/2000 Catalogne, 8-9/09/2002
Cévennes and 24-26/11/2002 Piémont encompass prototype flash-flood
situations in the western Mediterranean, attending to the relevant synoptic
and mesoscale signatures identified on the meteorological charts. A
prominent mid-tropospheric trough or cut-off low can be identified in all
events prior and during the period of heavy rains, which clearly served as
the precursor agent for the onset of the flash-flood conditions and the
cyclogenesis at low levels. Being aware of the uncertainty in the
representation of the upper-level disturbance and the necessity to cope with
it within the operational context when attempting to issue short to
mid-range numerical weather predictions of these high impact weather events,
a systematic exploration of the predictability of the three selected case
studies, subject to uncertainties in the representation of the upper-level
precursor disturbance, is carried out in this paper by means of numerical
simulations. |
