Synchronization phenomena of extreme weather events in Greece

The synchronized occurrences of heavy rainfall (and other extreme weather events), as well as the study of their relationship to time and space are of great socio-economic importance, for example in agriculture and insurance sectors, but also for the general well-being of the population.

Περίληψη:The synchronized occurrences of heavy rainfall (and other extreme weather events), as well as the study of their relationship to time and space are of great socio-economic importance, for example in agriculture and insurance sectors, but also for the general well-being of the population. In this study, the structure of spatial synchronization of rainfall is analyzed as a regional climatic network pertaining to the region of Greece and constructed from the time series of the corresponding meteorological parameters examined. The similarity between a series of events of rainfall is determined by the number of synchronized occurences. So we construct and analyze climate networks by using a python package which is pyunicorn. Also , what we are trying to achieve in our research, apart from synchronizing the occurrence of extreme rainfall events, is to examine whether these rainfall events are in agreement with a classification , derived from the cost73class project by using geopotential height data (850hpa) for the same time period (1979-2018) and for the same region (Greece). We want to find if they explain each other and if they complement each other. Finally, we understand that this is how we achieve 3 things. (1) Constructing and analyzing climate networks, (2) Weather type classification, and (3) Linking the previous ones to the synchronized episodes of extreme rainfalls.
