“…As the STJ slides to the north of Himalayas and Tibet at about 40°N and reforms over central Asia during the summer months, the summer monsoon cell finally develops (Ramaswamy, 1962;Pai and Rajeevan, 2007;Yin, 1949). This is especially important for climatic variability in the EM, since during summer the intensity and position of the STJ over the Mediterranean are key parameters for the climate variability over the region regarding heat wave events and precipitation (Baldi et al, 2006;Brikas et al, 2006;Gaetani et al, 2011;Prezerakos and Flocas, 2002).…”

“…At the level of the jet stream (Figure 7a) at 300 hPa, there is a meridional (southwesterly) flow of the jet stream above Algeria and the central Mediterranean Sea which turns anticyclonically and becomes zonal above the Balkans, where the jet streak is located. According to [93], a pattern of this kind, where the jet stream is north-northwest of Greece and anticyclonically curved, causes strong subsidence (Figure 7b) of the air masses leading to adiabatic heating of the lower troposphere above Greece. This contribution further enhances the heating from the warm air advection in the lower troposphere, which seemed to be the main driver of the heatwave.…”

“…Finally, a wedge of warm air coming from the Sahara Desert raised the temperature of the lower troposphere and the position of the jet stream northwest of Greece resulted in a downward atmospheric motion that led to the amplification of the warming due to thermal compression of the air. These atmospheric and land factors have previously been studied for heatwaves in relation to soil moisture content [94,[98][99][100][101], blocking highs [102][103][104], atmospheric heat transfer [105], jet stream position [93] and SSTs [106].…”

“…Ο STJ, που στην περίπτωση των ισχυρών ετών φαίνεται ότι φτάνει μέχρι και την περιοχή της EM, παίζει σημαντικό ρόλο στη μεταβλητότητα του κλίματος αυτής, καθώς κατά τη διάρκεια του καλοκαιριού η θέση και η έντασή του πάνω από τη Μεσόγειο σχετίζονται με την εμφάνιση των επεισοδίων καύσωνα και βροχόπτωσης στην περιοχή (Baldi et al, 2006;Brikas et al, 2006;Gaetani et al, 2011;Prezerakos and Flocas, 2002).…”
