“…Figure 10e shows the difference between high correlation models (average of CCSM4 and CNRM-CM5) and LC models. The synoptic-scale eddy activity is defined as the root mean square of the 2-8 day band pass filtered daily mean geopotential height at this level (e.g., Chang and Fu 2002;Lee et al 2012;Chen et al 2014). Note that results in other pressure levels (e.g., 850 and 500 hPa) are similar to those derived from 250 hPa (not shown).…”

“…Interpretations by Moore et al (2002a, b) and Rupper et al (2004) for extremes in the NWC accumulation record are consistent with some key features of the Pacific North American (PNA) and Pacific Decadal Oscillation (PDO) climate teleconnection patterns (Trenberth and Hurrell, 1994;Mantua and Hare, 2002). These patterns are recognized as influential for storm tracks, precipitation, and glacier mass balance in western North America (e.g., Hodge et al, 1998;Bitz and Battisti, 1999;Moore and Demuth, 2001;Demuth and Keller, 2006;Whitfield et al, 2010;Lee et al, 2012). PDOlike spectral periodicities were also identified in time series of sea-salt ions (Na + , Cl -) from the Mt.…”

ABSTRACT. A major achievement in research supported by the Kluane Lake Research Station was the recovery, in 2001 -02, of a suite of cores from the icefields of the central St. Elias Mountains, Yukon, by teams of researchers from Canada, the United States, and Japan. This project led to the development of parallel, long (10 3 -10 4 year) ice-core records of climate and atmospheric change over an altitudinal range of more than 2 km, from the Eclipse Icefield (3017 m) to the ice-covered plateau of Mt. Logan (5340 m). These efforts built on earlier work recovering single ice cores in this region. Comparison of these records has allowed for variations in climate and atmospheric composition to be linked with changes in the vertical structure and dynamics of the North Pacific atmosphere, providing a unique perspective on these changes over the Holocene. Owing to their privileged location, cores from the St. Elias Icefields also contain a remarkably detailed record of aerosols from various sources around or across the North Pacific. In this paper we review major scientific findings from the study of St. Elias Mountain ice cores, focusing on five main themes: (1) The record of stable water isotopes (δ 18 O, δD), which has unique characteristics that differ from those of Greenland, other Arctic ice cores, and even among sites in the St. Elias; (2) the snow accumulation history; (3) the record of pollen, biomass burning aerosol, and desert dust deposition; (4) the record of long-range air pollutant deposition (sulphate and lead); and (5) the record of paleo-volcanism. Our discussion draws on studies published since 2000, but based on older ice cores from the St. Elias Mountains obtained in 1980 and 1996.

“…Following previous studies (e.g. Lee et al, 2011Lee et al, , 2012, the North Pacific storm track intensity is defined as the area-averaged storm track activity over the region of 35 ∘ -60 ∘ N and 150 ∘ E-140 ∘ W. The annual cycle of the North Pacific storm track intensity displays a bimodal distribution, with the maximum appearing in April and November (Figure 10). Hence, the intensity of North Pacific storm track activity plays an important role in determining whether the variability of AO can exert influences on the subsequent SST anomalies in the tropical central-eastern Pacific.…”

“…Following previous studies, the synoptic-scale eddy activity is defined as the root mean square of the 2-to 8-day band-pass filtered geopotential height at 300 hPa (e.g. Lee et al, 2012).

Previous studies suggested that the variability of boreal spring Arctic Oscillation (AO) can exert a significant influence on the sea surface temperature (SST) anomalies in the Niño-3.4 region during the following winter. This study further reveals that AO in November can have a pronounced influence on the tropical central-eastern Pacific SST anomalies during the following spring and summer. When the November AO is in its positive (negative) phase, SST anomalies tend to be positive (negative) during the following spring and summer in the tropical central-eastern Pacific. The influence of the AO is accomplished by atmospheric circulation anomalies over the subtropical North Pacific through an interaction between the synoptic-scale eddy and the low-frequency mean flow. In the positive November AO years, pronounced cyclonic circulation and atmospheric heating anomalies are observed over the subtropical North Pacific. The atmospheric heating anomalies sustain westerly wind anomalies over the tropical western North Pacific through a Gill-like atmospheric response. The westerly wind anomalies extend eastward subsequently through positive air-sea feedback mechanism, and result in SST warming during the following spring and summer in the tropical central-eastern Pacific. Results of this study imply that the November AO index can be used as an effective predictor of SST anomalies in the Niño-3.4 region during the following spring and summer.
