Winter convective precipitation variability in southeastern Europe and its connection to middle tropospheric circulation for the 60-year period, 1950-2009 (Journal article)

Lolis, C. J.

The inter-annual variability of winter convective precipitation rate (CPR) in southeastern Europe and its connection to 500 hPa geopotential height (GH) is examined for the period 1950-2009 by using factor analysis and canonical correlation analysis. Two GH centers of action for CPR are found. The first one is located over Italy and it is associated with the typical winter depression activity regime over the Mediterranean Sea, controlling CPR in southern Italy, the southern Balkans, west Asia Minor, and the adjacent seas. The second one is located over the British Isles and it is associated with blocking activity over western Europe being responsible for a CPR seesaw teleconnection between (1) northern Italy, the Alps and the northwestern Balkans and (2) the south central Mediterranean Sea, south of Sicily. A CPR decrease in most of the areas under study and a CPR increase in the south central Mediterranean Sea are found.
