“…1 and 2) is the northern end member for calculation of the North Atlantic Oscillation (NAO) index (Dawson et al, 2002;Hurrell et al, 2003;Kwok and Rothrock, 1999;Zhang et al, 2004) and is effected by variations in sea ice and freshwater, exported through Fram Strait which is associated with the Arctic Oscillation (AO) (Thompson and Wallace, 1998;Wang and Ikeda, 2000;Darby et al, 2012). Our records in this paper cannot detect multi-year oscillations, but they can resolve multidecadal to -millennial periodicities.…”

“…When compared with the foraminifera-based climate divisions from the near by core BS1191-K14 (Table 1) (Jennings and Weiner, 1996) there are some associations and the Little Ice Age (LIA) appears to be represented by an increase in quartz and plagioclase but larger peaks occur between the LIA and the Medieval Warm Period (MWP). Wanner et al (2011) suggested two cold intervals within the last 2000 cal yr at 500 and 1500 AD -the former event (the socalled Dark Ages cold event) is marked by maximum wt% values of quartz and plagioclase and relatively large deviations in mineralogy.…”

Abstract. In the area of Denmark Strait (∼ 66 • N), the two modes of the North Atlantic Oscillation (NAO) and Arctic Oscillation (AO) are expressed in changes of the northward flux of Atlantic water and the southward advection of polar water in the East Iceland current. Proxies from marine cores along an environmental gradient from extensive to little or no drift ice, capture low frequency variations over the last 2000 cal yr BP. Key proxies are the weight% of calcite, a measure of surface water stratification and nutrient supply, the weight% of quartz, a measure of drift ice transport, and grain size. Records from Nansen and Kangerlussuaq fjords show variable ice-rafted debris (IRD) records but have distinct mineralogy associated with differences in the fjord catchment bedrock. A comparison between cores on either side of the Denmark Strait (MD99-2322 and MD99-2269) show a remarkable millennial-scale similarity in the trends of the weight% of calcite with a trough reached during the Little Ice Age. However, the quartz records from these two sites are quite different. The calcite records from the Denmark Strait parallel the 2000 yr Arctic summer-temperature reconstructions; analysis of the detrended calcite and quartz data reveal significant multi-decadal-century periodicities superimposed on a major environmental shift occurring ca. 1450 AD.

ABSTRACT:The potential dynamical predictability of the winter Arctic Oscillation (AO) is investigated using the ensemble hindcast from the Pusan National University coupled general circulation model (PNU-CGCM) over the 30-year period of 1981-2010. The analysis indicates that PNU-CGCM can not only reproduce the spatial distribution of the AO but also significantly simulate the AO's temporal variability. In addition, the coupled model performs well in terms of predicting the AO's impact on the Northern Hemisphere winter climate. These results reveal the coupled model's potential for dynamical forecasting of the climate over the mid-latitude to high latitude.
