Summary:
This thesis aims at the synoptic and mesoscale dynamic study of a powerful convective system that affected the Greek area on July 10, 2019, with structure and characteristics supercell storm, causing several material disasters, while the extreme weather phenomena killed 7 people. For the study of the storm system, satellite images from the MSG satellite were used, weather charts of pressure, temperature and winds at various isobaric levels, as well as dynamic parameters. At the upper layers, the disturbance that moved southeast, from northern Italy to northern Greece, caused the instability of the atmosphere, since the warm air masses that had been idle in the previous days forced upward movements. Also, an important role was played by the cold transfer to the lower levels, as well as the latent heat that gave energy for the development of the cloud. Finally, the intense heat gradient in the lower layers led the atmosphere to a strong baroclinicity.
