L'épisode pluvieux catastrophique des 12 et 13 novembre 1999 dans l'Aude et les départements voisins : analyse pluviométrique et météorologique. / The catastrophic rainfall of the 12 and 13 November 1999 in the Aude and neighbouring departments : a pluviométrie and meteorological analysis

摘要

The article analyzes both the climatological and the meteorological aspects of the rainfalls of the 12 and 13 november 1999. By placing the accumulation of rainfall in a regional and historical perspective, confirmation is given of the exceptional nature of the rainfall in the Aude valley and surrounding river basins. The extent of the areas affected, the interdependence between the heavy rainfall and the relief, and the somewhat unusual atmospheric conditions renders this event a precedent, making it necessary to reconsider some of the accepted notions concerning strong Mediterranean storms.
