| Zusammenfassung |
| This paper presents an analysis of the exceptionally high maximum (Tmax) and
minimum (Tmin) temperatures which occurred during November 2010 and affected
the entire Greek region. This severe "warm cold-season spell" was unusual
because of its prolonged duration and intensity for the entire month and
particularly the maximum temperature anomalies, which in comparison with the
1958–2000 climatological average, exceeded 5 °C at several stations.
Comparing the observed record with future projections from three regional
climate models revealed that Tmax and Tmin, on several days in November 2010,
exceeded the 90th percentile of the simulated data. An examination of
the atmospheric – synoptic conditions during this period showed that the
anomalous high temperatures could probably be related to the negative phase
of the Eastern Mediterranean Pattern (EMP), with an intense pole of negative
anomalies located over the British Isles, and to the east, a second pole of
positive anomalies, centred over the Caspian Sea. Finally, an attempt is
made to further investigate the mechanisms responsible for this phenomenon,
for example, the thermal forcing in the tropics (Niño 3 or Niño
3.4). |
