1400 years of extreme precipitation patterns over the Mediterranean
French Alps and possible forcing mechanisms.
Quaternary Research, Vol. 78, Issue 1, July 2012, pp. 1-12.
DOI: 10.1016/j.yqres.2012.03.003
Investigation of Lake Allos sediments revealed ~160 graded layers,
interpreted as flood deposits, over the last 1400 yr. Comparisons
with records of historic floods support the interpretation of flood
deposits and suggest that most recorded flood events are the result
of intense meso-scale precipitation events. As there is no evidence
for any major changes in erosion processes in the catchment since
the Medieval Warm Period (MWP), we interpret the Allos record
in terms of repeated intense precipitation events over the last
millennium, with a low flood frequency during the MWP and more
frequent and more intense events during the Little Ice Age.
This interpretation is consistent with the pattern of increasingly
humid conditions in the northwestern Mediterranean region. This
long-term trend is superimposed on high frequency oscillations
that correlate with solar activity and autumnal North Atlantic
Oscillation (NAO). Finally, a comparison of flood records across
the northwestern Mediterranean region showed that intense
precipitation events in Allos (east of the Rhône Valley)
were out of phase with events in the Cévennes (west of the Rhône)
but in phase with events in eastern Spain. Supported by meteorological
analyses, this suggests an oscillation in atmospheric circulation
patterns over the northwestern Mediterranean.
STUDY NOTES: Annual flood deposit thickness data from Lake Allos, Mediterranean
French Alps, for the past 1360 years. The Lake Allos sediment sequence
consists of 160 normally graded beds containing markers indicating
an allochtonous origin for the sediment (terrestrial macro-remains
and Ca-enrichment). These beds are interpreted as flood deposits,
associated with extreme precipitation events in the northwest
Mediterranean region. Grain size analysis (Malvern Mastersizer S)
was conducted on core ALO09P13, retrieved from the northern basin
of the lake. Sampling was at a continuous interval of 5 mm.
Lake Allos, Mediterranean French Alps:
44°14.16'N, 6°42.55'E, 2230m elevation, 20m water depth.
