Comparisons \r\nwith records of historic floods support the interpretation of flood \r\ndeposits and suggest that most recorded flood events are the result \r\nof intense meso-scale precipitation events. As there is no evidence \r\nfor any major changes in erosion processes in the catchment since \r\nthe Medieval Warm Period (MWP), we interpret the Allos record \r\nin terms of repeated intense precipitation events over the last \r\nmillennium, with a low flood frequency during the MWP and more \r\nfrequent and more intense events during the Little Ice Age. \r\nThis interpretation is consistent with the pattern of increasingly \r\nhumid conditions in the northwestern Mediterranean region. This \r\nlong-term trend is superimposed on high frequency oscillations \r\nthat correlate with solar activity and autumnal North Atlantic \r\nOscillation (NAO). Finally, a comparison of flood records across \r\nthe northwestern Mediterranean region showed that intense \r\nprecipitation events in Allos (east of the Rhône Valley) \r\nwere out of phase with events in the Cévennes (west of the Rhône) \r\nbut in phase with events in eastern Spain. Supported by meteorological \r\nanalyses, this suggests an oscillation in atmospheric circulation \r\npatterns over the northwestern Mediterranean. ","author":null,"citation":"Wilhelm, B., F.
