Regional Climate Change and Extremes.

Résumé

Global coupled ocean-atmosphere models, driven by greenhouse gas concentrations according to several hypotheses for the next century, have been used in the last IPCC-AR4 report to depict possible future climates of the planet. It will be shown that a regional atmosphere model is able to represent with some fidelity the different climates over France, thanks to a realistic representation of the main mountains. Local extreme phenomena like intense precipitations are better taken into account. Regional models are an essential link between physical hypotheses (e.g. 2x versus 3x CO2 concentration) and needs from the impact community.
