| description | The objective on this paper is to compare the extreme rainfall characteristics, deduced from the best modelled probability distribution functions and the actual precipitation measurements, obtained at the Department of Meteorology and Climatology of the Aristotle University of Thessaloniki meteorological station. To meet this objective, the proven best models for the simulation of the annual and seasonal extreme rainfall events at the Thessaloniki meteorological station, that is: Generalized Pareto, Johnson SB, log-Pearson and Fatigue Life (3P) probability distribution models, are appropriately applied
to generate the extreme rainfall characteristics for the period 1947-2003. The measures of central tendency and variability, for regular and ordinal data, are calculated -in an annual and seasonal basis- in order to compare the two different approaches. Hence the deviations between and among the measured and the modelled values of rainfall: means, medians, standard deviations, variance, skewness and kurtosis, are compared to demonstrate any existent difference. The deviations between the projected and actual measures of central tendency values are discussed, with respect to the contribution on climate change. |
