Résumé

Climate change projections are frequently analysed through the Circulation Types (CTs). Projected changes in the frequency of the CTs can help to understand the influence degree of several forcings on the atmospheric dynamics and some climate variables. Nevertheless this method has not been used enough for paleosimulations. This study analyses the behavior in the frequency of the main CTs obtained for winter and summer from a paleosimulation performed for Europe and the Iberian Peninsula for the last millennium (1001- 1990) using a climate version of MM5. The simulation includes three kind of external forcings: Greenhouse Gases (industrial period), volcanic activity (maximun near 1810) and solar activity (minimun around 1700). For the characterization of the CTs were employed daily data of Sea Leve Pressure (SLP) and Geopotential Height at 500 hPa Level of a window that covers the Iberian Peninsula (IP). The results indicate the existence of an important variability of the frequency series of the CTs along the millennium, when significant relationships between external forcings and some frequency series were found.
