Zusammenfassung |
The objective of this study is to investigate the relationship of orography
over Greece with prolonged dry spells, as represented by the maximum number
consecutive dry days (CDD index) during an extremely dry summer. For this
purpose a simulation experiment was conducted with the aid of the regional
climate model RegCM3.1 using a spatial resolution of 10 km. It was shown
that a significant precipitation regime formed over the mountainous areas of
continental Greece and Crete during this dry summer, due to orographically
forced precipitation, consequently influencing the length of dry spells.
Furthermore, the CDD appears spatial variations over the maritime areas,
despite the zero or insignificant precipitation. The sensitivity test that
was performed with the elimination of orography demonstrated the important
role that orography plays in the distribution of CDD, since significant
lengthening of extreme dry spells was found over the mountainous areas. |
