Bise
The Bise or the Biswind is a word known in the southwest of the German-speaking area (South Baden, Switzerland, Vorarlberg) for a cutting cold, dry and brightening wind blowing from the north, northeast or east .
The technical language of meteorology, on the other hand, limits the word to a regional Swiss wind system that only occurs in the Swiss plateau. The mostly dry, cold wind from east to north-east in the Swiss plateau is fed by continental air flowing from north-east Europe to central Europe when there is high pressure in Europe north of Switzerland and low in the Mediterranean region . In summer, a Bisenlage usually means nice weather with pleasantly cool temperatures. In winter there is often high fog or heavy haze in lower elevations .
Because of the narrowing canals through the Alps and the Jura towards the west, the Bise reaches its greatest strengths in the Lake Geneva area , where average wind speeds of 60 km / h and gusts of up to over 100 km / h are not infrequently registered in the classic Bise position. At Lake Constance the bise is weaker and manifests itself as a relatively cool north to north-east wind with mostly less than 6 Beaufort (40–50 km / h).
The word Bise first appeared in Notkers III's writings . occupied by St. Gallen, is an Alemannic word whose origin is uncertain. Presumably it belongs to the word family of Old High German bĭsōn , 'around-, storming in'; Attempts to derive the word as a borrowing from Gallo-Roman or to combine it with breeze are rejected today.
