Q

the parent cyclones are located over Eastern Europe and the resulting cyclogenesis took place over the Aegean Sea and or the lee of the Taurus Mountains.

All of these cyclones reached the

eastern part of the MB and then moved further to the east or turned north, at southeast Turkey, toward the Black Sea

Q

All of these cyclones reached the eastern part of the MB and then moved further to the east or turned north, at southeast Turkey, toward the Black Sea (Fig. 3.a). In some cases the “daughter” Mediterranean cyclone, when reaching the Black Sea, generated

A

another cyclone in the eastern Mediterranean that can be referred as a “granddaughter cyclone”.

Q

In the second scenario (25.5%), the cyclones are generated over the western part of the MB, mostly in the Gulf of Genoa or the lee of the Pyrenees, under the influence of Atlantic cyclones, which became European cyclones (Fig. 3.b). These cyclones moved

A

eastward and when reaching Italy or the Aegean Sea turned northward and merged with the European cyclone track. Only 10% of those cyclones reached the eastern MB.

Q

In the third scenario (23.5%), the cyclones are generated at the central MB, mostly south of the Italian Alps. The “parent” cyclones are located over

A

central Europe, almost precisely north of the region of the Mediterranean cyclogenesis (Fig. 3.c). 10.7% of those cyclones reached the eastern MB.

Q

To conclude, the location of the “parent” cyclone with respect to the MB, determines the

Q

To conclude, the location of the “parent” cyclone with respect to the MB, determines the location of the cyclogenesis, and the tracks of the “daughter” cyclone. Generally, for parent cyclones located over Western Europe, the cyclogenesis took place

A

southeast of it.

Q

For central Europe, it took place to the

A

south

21
Q

for Eastern Europe the cyclogenesis took place to the

A

southwest

22
Q

After their formation, the “daughter” cyclones move

A

mostly eastward;

some of them reach the Eastern MB,

some of them dissipate in the central MB and

the rest merge with the European cyclone track.

23
Q

The further the cyclogenesis is from the Eastern MB, the

A

smaller is the chance of the “daughter” cyclone reaching that region

24
Q

The MB is frequently found to be dominated by

A

an easterly flow associated with a north-south pressure gradient.

25
Q

The MB is frequently found to be dominated by an easterly flow associated with a north-south pressure gradient. Under these circumstances troughs extended from

A

Africa

26
Q

Under these circumstances troughs extended from Africa, within which cyclones develop over the

A

southern coasts of the Mediterranean

27
Q

Under these circumstances troughs extended from Africa, within which cyclones develop over the southern coasts of the Mediterranean. Such a development, which can be considered as

A

reflecting transformation of tropical disturbances to extratropical cyclones

28
Q

Such a development, which can be considered as reflecting transformation of tropical disturbances to extratropical cyclones, is observed in the

A

western, central and eastern parts of the MB

29
Q

Such a development, which can be considered as reflecting transformation of tropical disturbances to extratropical cyclones, is observed in the western, central and eastern parts of the MB. This scenario is responsible for

A

34.5% of the cyclones generated in the MB

30
Q

The first (……..% of the cases) is the

A

68.5

eastern part of the MB

31
Q

The first (68.5% of the cases) is the eastern part of the MB. An example of such a development is the so-called

A

Red Sea trough

32
Q

The first (68.5% of the cases) is the eastern part of the MB. An example of such a development is the so-called Red Sea trough, within which a cyclone is formed near

A

Cyprus

33
Q

The first (68.5% of the cases) is the eastern part of the MB. An example of such a development is the so-called Red Sea trough, within which a cyclone is formed near Cyprus (Fig. 4.a). These cyclones move

A

eastward toward the eastern coast of the Mediterranean or turn northward, down to the Black Sea

34
Q

The second (…………% of the cases) is the

A

31.5

western and the central parts of the MB, Sardinia, Sicily and north Libya

35
Q

The second (31.5% of the cases) is the western and the central parts of the MB, Sardinia, Sicily and north Libya. In most cases, these cyclones move

A

eastward along the southern coasts of the Mediterranean, and reached its eastern coast

36
Q

The second (31.5% of the cases) is the western and the central parts of the MB, Sardinia, Sicily and north Libya. In most cases, these cyclones move eastward along the southern coasts of the Mediterranean, and reached its eastern coast (Fig. 4.b). The trough within which these cyclones were formed in the western part of the Mediterranean was oriented mostly

A

southwest-northeast

37
Q

In most cases, these cyclones move eastward along the southern coasts of the Mediterranean, and reached its eastern coast (Fig. 4.b). The trough within which these cyclones were formed in the western part of the Mediterranean was oriented mostly southwest-northeast (Fig. 4.b), but for those which developed in the eastern MB the orientation of the trough is

A

south-north

38
Q

Several cyclones are found to be generated by a “parent cyclone” which is itself a Mediterranean cyclone (Fig. 5). This scenario includes only

A

4.5% of the cyclones generated in the MB

39
Q

Several cyclones are found to be generated by a “parent cyclone” which is itself a Mediterranean cyclone (Fig. 5). This scenario includes only 4.5% of the cyclones generated in the MB. It occurs when a

A

Mediterranean cyclone reaches the eastern part of the MB

40
Q

This scenario includes only 4.5% of the cyclones generated in the MB. It occurs when a Mediterranean cyclone reaches the eastern part of the MB and develops a

A

a trough to its west, toward the central part of the Mediterranean

41
Q

This scenario includes only 4.5% of the cyclones generated in the MB. It occurs when a Mediterranean cyclone reaches the eastern part of the MB and develops a trough to its west, toward the central part of the Mediterranean. In this trough, a………………… develops

A

“daughter cyclone”

42
Q

It occurs when a Mediterranean cyclone reaches the eastern part of the MB and develops a trough to its west, toward the central part of the Mediterranean. In this trough, a “daughter cyclone” develops, mostly next to the

A

Italian peninsula

43
Q

It occurs when a Mediterranean cyclone reaches the eastern part of the MB and develops a trough to its west, toward the central part of the Mediterranean. In this trough, a “daughter cyclone” develops, mostly next to the Italian peninsula. The “daughter cyclone” tends to move

A

eastward either to the eastern MB or northward reaching the coast of southern Turkey

44
Q

Mediterranean migrating cyclones are associated with

A

cold upper troughs

45
Q

Mediterranean migrating cyclones are associated with cold upper troughs. The existence of an upper-level trough implies the

A

intrusion of cold air from high latitudes

46
Q

Mediterranean migrating cyclones are associated with cold upper troughs. The existence of an upper-level trough implies the intrusion of cold air from high latitudes leading to

A

instability and cyclogenesis over the Mediterranean

47
Q

Mediterranean migrating cyclones are associated with cold upper troughs. The existence of an upper-level trough implies the intrusion of cold air from high latitudes leading to instability and cyclogenesis over the Mediterranean. An upper-level trough is present in both

A

moderate and extreme rainfall, but the trough is narrower and deeper in the extreme precipitation events, in all seasons.

48
Q

An upper-level trough is present in both moderate and extreme rainfall, but the trough is narrower and deeper in the extreme precipitation events, in all seasons.

For example:

A

Cyprus low develops when an upper-level trough enters EM bringing cold air from eastern Europe over the warmer Mediterranean. The cold air invasion is associated with advection of positive vorticity in the upper levels, with a presence of upper-level ridge over western Europe.
