Abstract. We investigate the climate signature of δ18O tree-ring records from sites distributed all over Europe covering last 400 years. An empirical orthogonal function (EOF) analysis reveals two distinct modes variability on basis existing records. The first mode is associated with anomaly patterns projecting onto El Niño–Southern Oscillation (ENSO) and reflects a multi-seasonal climatic sign...
