From Glossary of Meteorology


A south wind of foehn type descending from the Pyrenees in the Ariège valley, France.

It is especially violent in February and March when it melts the snow, flooding the rivers, and sometimes causing avalanches. It causes a premature spring that forces the buds on fruit trees, which are subsequently killed by frost. In August and September it comes as a strong drying wind, generally lasting three to four days.
