Vb weather conditions

Older but still common term for a special general weather situation in
Central Europe. It goes back to a special train route (Vb) of the low-pressure areas (Vb-
lows) in Europe. The Zugstrasse Vb leads from the Adriatic Sea across eastern Central Europe
northbound. There is a so-called high-altitude trough (a low-pressure zone in higher
air layers) over Central Europe. These generally very precipitation-intensive weather conditions
(Example: August flood 2002) occur relatively rarely.
