Zusammenfassung |
In this study, the spatial and temporal variability of the mean annual rain
intensity in Greece are examined during a 41-year period (1962–2002). The
meteorological datasets concern monthly rain amounts (mm) and the respective
monthly durations (h) recorded at thirty two meteorological stations of the
Hellenic National Meteorological Service, which are uniformly distributed on
Greek territory, in order to calculate the mean monthly rain intensity. All
the rain time series used in the analysis were tested by the application of
the short-cut Bartlett test of homogeneity. The spatial distribution of the
mean annual rain intensity is studied using the Kriging interpolation
method, while the temporal variability, concerning the mean annual rain
intensity trends along with their significance (Mann-Kendall test), is
analysed.
The findings of the analysis show that statistically significant negative
trends (95% confidence level) appear mainly in the west sub-regions of
Greece, while statistically significant positive trends (95% confidence
level) appear in the wider area of Athens and the complex of Cyclades
Islands. Further analysis concerning the seasonal rain intensity is needed,
because there are different seasonal patterns, taking into account that,
convective rain in Greece occurs mainly within the summer season. |
