Individual seasonality index of rainfall regimes in Greece

Abstract

The study of rainfall seasonality in different geographical areas in Greece using an individual seasonality index was the purpose of the present work. The correlation of the seasonality index (S̄I, sum of the absolute deviation of mean monthly rainfall from the overall monthly mean divided by the mean annual rainfall) with the mean individual seasonality index (S̄I, average of SI, for each year i) was initially determined. A regression analysis of S̄I with geographical latitude resulted in a statistically significant inverse linear correlation. The time series trend of the SI, was examined to verify that no significant change in rainfall seasonality occurred. © Inter-Research 2005.
