| Dynamically induced rainfall is strongly connected with
synoptic atmospheric circulation patterns at the upper levels. This study
investigates the relationship between days of high precipitation volume
events in the eastern Mediterranean and the associated geopotential height
patterns at 500 hPa. To reduce the number of different patterns and to
simplify the statistical processing, the input days were classified into
clusters of synoptic cases having similar characteristics, by utilizing
Kohonen Self Organizing Maps (SOM) architecture. Using this architecture,
synoptic patterns were grouped into 9, 18, 27 and 36 clusters which were
subsequently used in the analysis. The classification performance was tested
by applying the method to extreme rainfall events in the eastern
Mediterranean. The relationship of the synoptic upper air patterns (500 hPa
height) and surface features (heavy rainfall events) was established, while
the 36 member classification proved to be the most efficient. |
