Περίληψη | Cyclones passing over Crete originate mainly from southwest, west and northwest directions and
are of varying size and intensity. A number of these cyclones cause flash floods. In this study, an
attempt was made to associate the synoptic scale atmospheric circulation patterns prevailing over
the eastern Mediterranean region with flood occurrences in Crete during the period 1991 to 2009.
The atmospheric circulation conditions during the flood events were examined based on ERA
Interim reanalysis datasets with resolution T255 for spectral field (or about 79km x79km) available
from ECMWF. The atmospheric circulation was classified in 6 synoptic types, according to the
wind flow and geopotential or pressure pattern at 500 hPa and surface, respectively. The Melbourne
University Cyclone Tracking Algorithm was employed to examine the genesis, tracks and depth of
these cyclones.
It was found that in the vast majority of the flood events the respective cyclones develop over the
Adriatic and Ionian seas and then affect the western part of Crete. The cyclones are mainly
attributed to the category CLOSE, revealing characteristics of vertically organized baroclinic
systems. The cyclones appear their maximum intensity before they affect Crete, mainly over
western Mediterranean, implying the synergy of topographical factors. They are mainly
characterized by long duration and track length. | en |
