Photo camera in hand: Puy de Dome volcano. Views of Auvergne.

Puy de Dome is the highest volcano in the chain of volcanoes Chaine des Puys. Is it extinct or just dormant, the point is being open to the inquiry and scientific argumentations. By its position on the continent and its topography, the horizontal flow of moist dominant west, an area of strong transitions climate, the mountains to the plains and the ocean at continental, generating diversity and paradoxes. Thus rainfall varies from one to four of the driest wetter. The mountains of southwest (Sancy, Cezallier) are abundant rainfall and snow, while Limagnes at the center are protected by a powerful effect Foehn and see more public thunderstorms in total precipitation. At the Foehn is fading with the approach of other mountains (Livradois, Forez). The gap between the average thermal places the hottest and the coldest was 8 degree, but in winter the plains are often colder than the mountains (inversion phenomenon).
