In contrast, our \r\nresults show that the Medieval Climate Anomaly (1150-650 cal yr BP) \r\nwas characterised by low storm activity. The evidence for high \r\nstorm activity in the NW Mediterranean Sea is in agreement with \r\nthe changes in coastal hydrodynamics observed over the Eastern \r\nNorth Atlantic and seems to correspond to Holocene cooling in\r\nthe North Atlantic. Periods of low SSTs there may have led to \r\na stronger meridional temperature gradient and a southward \r\nmigration of the westerlies. We hypothesise that the increase \r\nin storm activity during Holocene cold events over the North \r\nAtlantic and Mediterranean regions was probably due to an \r\nincrease in the thermal gradient that led to an enhanced \r\nlower tropospheric baroclinicity over a large Central \r\nAtlantic-European domain.\r\n","author":null,"citation":"Sabatier, P., L.
