Dynamics of primary climatic parameters in the greater region of Europe and Greece
Summary:
The subject of the present thesis is the study of the dynamics of climatic parameters, and more specifically, the assessment climatic trends of temperature and specific and relative humidity both at the surface and in multiple pressure levels in the atmosphere. The study was conducted for the wider region of Europe and focuses on the region of the eastern Mediterranean and more specifically in the greater region of Greece. Reanalysis data from the Copernicus database were used to identify climatic trends, from the ERA5 reanalysis product with a spatial resolution of 0.25° x 0.25° for the period 1979-2018 (40 years). The Mann-Kendall statistical test was applied to the data and then the Sen’s slope estimator to identify the climate trends at each grid point. For the development of the database and for the processing, analysis ana mapping of the climate datasets, Matlab routines were developed. The results of climate trends on temperature indicate heating in the troposphere and cooling in the stratosphere. Regarding the climatic trends of the specific humidity, mainly positive values prevail up to the mid-troposphere and then they tend to zero. Finally, the climatic trends of the relative humidity exhibit positive and negative values due to the influence of humidity and temperature in the atmosphere.
