Abstract

The cluster classification of provenances at a site in the NE Iberian Peninsula indicated that in the period of extended winter (December to March, DJFM) fast Atlantic air flows correspond to positive WeMO index (WeMOi), while negative WeMOi are associated to Mediterranean circulations. The amount of winter precipitation was inversely correlated with winter WeMOi. Wet deposition fluxes of marine-derived (Na+, Mg2+ and Cl-) and anthropogenic-derived (NO3- and K+) ions were significantly (and negatively) related to winter WeMOi.
