A Teleconnection Study of Interannual Sea Surface Temperature Fluctuations in the Northern North Atlantic and Precipitation and Runoff over Western Siberia

Abstract

Abstract The spatial distributions of northern North Atlantic sea surface temperature and the high-latitude Northern Hemisphere sea level pressure anomalies averaged over six consecutive warm SST winters (1951–1956) and six consecutive cold SST winters (1971–1976) are examined. Three SLP anomaly difference (i.e., warm - cold winters) centers, significant at the 5% level, are observed over the northern North Atlantic, Europe, and western Siberia. This anomaly pattern is consistent in principle with what was identified in a related analyses by Palmer and Sun, who used composite data from selected winter months. The SLP difference centers over the northern North Atlantic and western Siberia are in phase. The impact of the latter center upon the runoff from the underlying Oh and Yenisey rivers and especially the teleconnection between SST anomalies in the northern North Atlantic and runoff of those two rivers via the atmosphere are investigated. The temporal cross-correlation analyses of 50 years (1930–1979) ...
