| Zusammenfassung |
| Two recently-available daily gridded datasets are used to investigate trends
in Mediterranean temperature extremes since the mid-20th century. The
underlying trends are found to be generally consistent with global trends of
temperature and their extremes: cold extremes decrease and warm/hot extremes
increase. This consistency is better manifested in the western part of the
Mediterranean where changes are most pronounced since the mid-1970s. In the
eastern part, a cooling is observed, with a near reversal in the last two
decades. This inter-basin discrepancy is clearer in winter, while in summer
changes are more uniform and the west-east difference is restricted to the
rate of increase of warm/hot extremes, which is higher in central and eastern
parts of the Mediterranean over recent decades. Linear regression and
correlation analysis reveals some influence of major large-scale atmospheric
circulation patterns on the occurrence of these extremes – both in terms of
trend and interannual variability. These relationships are not, however,
able to account for the most striking features of the observations – in
particular the intensification of the increasing trend in warm/hot extremes,
which is most evident over the last 15–20 yr in the Central and Eastern
Mediterranean. |
