TL;DR: In this article, the sensitivity of the Weather Research and Forecasting (WRF) model rainfall predictions to the choice of two commonly used boundary layer schemes, is examined through the simulation of an exceptionally heavy rainfall event over Chalkidiki peninsula in northern Greece.

TL;DR: The results of simple correlation analysis showed that the daily number of epistaxes depends mainly on mean, maximum and minimum temperature and water vapour pressure, and the corresponding correlation coefficients are statistically significant, indicating an influence of weather on epistaxis up to 9% of its total variance.

TL;DR: In this paper, the relationship between atmospheric circulation over Europe and precipitation in Greece is studied during high winter (January-February) Specifically, the 850 hPa relative vorticity centres, affecting or related to precipitation in the various areas of Greece, are defined and the corresponding temporal variability of both parameters is examined Factor analysis is first applied on both fields, in order to reduce the dimensionality of the original data sets Canonical correlation analysis is then applied on the factor analysis results, to interrelate the two parameters.

TL;DR: In this article, 12 monthly climatic parameters of 49 Meteorological stations in Greece are classified according to their spatial covariability, in order to define groups of climatic elements having the same, characteristic, spatial distribution.

TL;DR: In this article, the main synoptic conditions associated with extreme precipitation amounts in Greece are examined by using a multivariate statistical methodology comprising S-mode Factor Analysis and k-means Cluster Analysis.
