| Résumé anglais |
The dynamics of the weather are determined by both local and distant factors. The recent evolution of the weather can be analysed according to two methods. The first, statistical and probabilistic, is founded on an analysis of observational data and gives only limited and uncertain results ; the second analyses the evolution of climatic parameters in a serological unit, namely the North Atlantic Ocean within which France is located. In this unit, controlled by the dynamics of MPHs, and due to Arctic cooling, the weather has become more violent since the 1970s and natural hazard have increased. It is a reality (operating in the opposite direction to the hypothetical global warming) which needs to be taken account of seriously in prevention programmes against the consequences of more violent weather.
