L'épisode neigeux de décembre 1990 dans la région Rhône-Alpes
Snowfalls in Rhône-Alps region (France) december 1990
Météo-France, Lyon
Abstract
Nearly all the activities of the RHONE-ALPS Region were disturbed by unusual snowfalls.
This was an unusual phenomen because of its location (essentially law-altitude regions) as well as by its importance.
Classically it was caused by the arrival of hot and humid air over a film of cold air and by disturbances being stuck before the Alps. It was a matter of a few hours time and of a few degrees.
Following the study of the meteorological situation and the distribution of the snow in time and space, it was necessary to handle the problems of excess load to together with the frequency of such a phenomen since it was a memorable event.
