Les excès climatiques dans le Massif central français. L'impact des temps forts pluviométriques et anémométriques en Auvergne.

Abstract : In our thesis, the term « excess » has a broader meaning than its common definition. Excess is perceveid with damage existence and it shows the synergism between an ominous weather (the high weather) and the vulnerabilities. According to how the relief of the Auvergne is placed, it has a tendency to further a higher frequency of pluviometric high weather by the southern and western region whereas the inner area has hardly been concerned by strong oceanic and mediterranean rainfalls. Nevertheless there are definitely more excesses in the basins than the mountains because of a higher vulnerableness in the urbanized low areas. Besides, these basins are sometimes affected by flood transfers coming from mountains.
The analysis of the disturbed systems which generate the high weather is carried out either in a conventional way with the isobaric map study or even more by using radar and satellite imagery. Radar prints prove to be determining in order to understand the evolution of the systems from the Cévennes and the stormy systems too. Of course, the most serious excesses occur when the high weathers directly touch the urbanized areas or when the most important flood transfers reach the bassins.
The whole work has ended at an identification of eleven territories which possess original characteristics in vulnerableness level, frequency and nature of high weathers together with excess significiance.
