Analysis of cyclone tracks over southern Europe and their effects on weather in the Adriatic region
The objective of this thesis is to develop a method for objective determination of cyclone trajectories over Europe, with a special analysis of the Adriatic area. The method consists of processing ERA-Interim reanalysis data for mean sea level pressure values taken from the ECMWF (European Center fo...
