Interdecadal Pacific Oscillation in Northern Greenland Dust Concentration Variability During the Last 400 Years

Abstract Statistical analysis of reanalysis and observed data reveals that high dust surface mass concentration in northern Greenland is associated with a Pacific Decadal Oscillation like pattern its negative phase the North as well La Niña conditions tropical region. The sea temperature anomalies realm resemble Interdecadal (IPO). atmospheric circulation pattern, form wave‐train from to Eurasian continent, favors enhanced uptake transport toward Greenland. Similar patterns are low‐resolution stacked record five Ca 2+ ice cores, is, ngt03C93.2 (B16), ngt14C93.2 (B18), ngt27C94.2 (B21), GISP2−B, NEEM‐2011‐S1, Greenland, proxy for regional concentration, during last 400 years. We argue core records could be used proxies IPO related teleconnections.
