%X A synthetic stalagmite ¦Ä18O record for the Bunker Cave (51¡ã N, 7¡ã E) is constructed using a combined climate¨Cstalagmite modelling approach where we combine an atmospheric circulation model equipped with water isotopes and a model simulating stalagmite calcite ¦Ä18O values. Mixing processes in the soil and karst above the cave represent a natural low-pass filter of the speleothem climate archive. Stalagmite ¦Ä18O values at Bunker Cave lag the regional surface climate by 3¨C4 yr. The power spectrum of the simulated speleothem calcite ¦Ä18O record has a pronounced peak at quasi-decadal time scale, which is associated with a large-scale climate variability pattern in the North Atlantic. Our modelling study suggests that stalagmite records from Bunker Cave are representative for large-scale teleconnections and can be used to obtain information about the North Atlantic and its decadal variability.
