| Résumé anglais |
The torrential rains of the 12 and 13 november 1999 over the Languedoc-Roussillon region were directly related with two very strong Moving Polar Highs (MPHs), the one located first over the Atlantic Ocean and then over the Western Mediterranean, and the other over Central Europe and then over the Eastern Mediterranean. The narrowing of the low pressure trough between the southern part of this two MPHs concentrated the very high Mediterranean energy and channelled it towards the Gulf of Lion. The low- level collision, along a meridian convergence line, of this very wet and rapid easterly streamflow and a part of the MPH which had followed an Atlantic path and had been diverted towards southwest France by the Cantabric-Pyrenean range, provoked a violent ascent and heavy rains with dramatic consequences.
