Resum
Compound extremes have increasingly become the focus of research in recent years, due to the strong impact
they have upon society and ecosystems. Few studies, however, address the role of teleconnection patterns in
these compound extremes, and how the former can be used to predict the latter. The present study quantifies the
changes observed in the monthly frequencies of Dry-Warm, Dry-Cold, Wet-Warm and Wet-Cold concurrent extremes
in the Mediterranean basin during the 1951–2020 period, and assesses the effect of different regional,
continental and oceanic teleconnections upon the frequency of such concurrent extremes. Results reveal a significant
increase, especially, in dry-warm months in large areas of the Mediterranean basin, mainly in summer
and spring, as well as a decrease in wet-cold extremes in these seasons. On the other hand, the positive phase of
the Mediterranean Oscillation (MO) has a strong capacity to drive dry-warm months in the western Mediterranean
basin, as well as wet-cold extremes in the southern-east part of the Mediterranean basin. This role becomes
inverted during the negative phase of this teleconnection. Furthermore, due to its subtropical linkage, the
positive phase of the East Atlantic (EA) oscillation also plays an important role in accounting for the occurrence
of dry-warm months in most of the Mediterranean basin, especially in the west and the north. During its negative
mode, the configuration of the EA dipole favours the occurrence of wet-cold months, especially in the north and
western part of the basin. The East Atlantic/Western Russia oscillation proved to be highly capable of inferring
the ocurrence of dry-warm and wet-cold events in the eastern Mediterranean. The other teleconnections analysed
(the North Atlantic Oscillation (NAO), the Western Mediterranean Oscillation (WeMO), and the Scandinavian
(SCAND) an Polar-Eurasia (POLEUR) oscillations) played a minor role in driving these monthly concurrent extremes.
The results provided by the present paper are intended to guide future research addressing the potential
of teleconnection patterns to drive the temporal variability of compound extremes.
