Zonal Jet Structure and the Leading Mode of Variability (2007, positive): “The Atlantic and Pacific sectors are defined according to Ambaum et al. (2001).”
Atmospheric bridge, oceanic tunnel, and global climatic teleconnections (2007, background): “anomalies over the Pacific often vary independently from those over the Atlantic [Deser, 2000; Ambaum et al., 2001].”
Variability of the North Atlantic eddy‐driven jet stream (2010, neutral): “This means that the eddy-driven jet is more easily separated from the subtropical jet (Lee and Kim 2003), for example during the positive phase of the NAO (Ambaum et al. 2001; Gerber and Vallis 2009).”
Asian Jet Waveguide and a Downstream Extension of the North Atlantic Oscillation (2004, background): “As mentioned in the introduction and also reported in many articles (e.g., Deser 2000; Wallace 2000; Ambaum et al. 2001; Kodera and Kuroda 2003), winter NAO and AO indices are highly correlated although the former (latter) is thought to represent a regional (hemispheric) pattern of variability.”
Dynamical feedbacks and the persistence of the NAO (2009, background): “The distinction between the NAO and the hemispheric variability of the Northern Hemisphere extra- tropical jet, coined the northern annular mode (NAM), has been a topic of debate (Thompson and Wallace 1998, 2000; Ambaum et al. 2001).”
The dynamics of NAO teleconnection pattern growth and decay (2003, methodology): “Over the past few years a debate has arisen as to whether the NAO or the annular mode is a more appropriate paradigm of lowfrequency variability (Wallace 2000; Deser 2000; Ambaum et al. 2001).”
Changes in atmospheric circulation over Europe detected by objective and subjective methods (2006, background): “the mode explaining the largest fraction of the total variation in data) is the North Atlantic Oscillation (NAO) (cf. Barnston and Livezey, 1987; Clinet and Martin, 1992; Ambaum et al., 2001).”
Independent Component Analysis of Climate Data: A New Look at EOF Rotation (2009, methodology): “Perhaps a good example is the ongoing debate within the climate community on whether the North Atlantic Oscillation (NAO) and the North Pacific Oscillation (NPO) are two different faces of the same coin [i.e., the Arctic Oscillation (AO)] (Ambaum et al. 2001; Vallis et al. 2004; Dommenget 2007).”
An Observed Connection between the North Atlantic Oscillation and the Madden-Julian Oscillation (2009, background): “Although highly correlated, whether the AO and NAO are the same phenomenon is not without a debate (Deser 2000; Ambaum et al. 2001; Wallace and Thompson 2002).”
The NAO Troposphere-Stratosphere Connection. (2002, neutral): “More details can be found in Ambaum et al. (2001).”
Tropospheric Rossby Wave Breaking and the NAO/NAM (2008, background): “These observations may provide a physical explanation for previous studies (Deser 2000; Ambaum et al. 2001), showing that the temporal coherence between Arctic and midlatitude circulation variability is stronger over the Euro-Atlantic area than over the Pacific and that the correlations between the ”
An Evaluation of the Large‐Scale Atmospheric Circulation and Its Variability in CESM2 and Other CMIP Models (2020, background): “The NAO is highly correlated with the Arctic Oscillation, or NAM, but reflects variability that is more localized to the North Atlantic sector and is argued by Ambaum et al. (2001) to be a more physically relevant mode of variability for the NH than the zonally symmetric NAM.”
The ``Year'' of Tropical Convection (May 2008-April 2010): Climate Variability and Weather Highlights (2012, background): “…the manifestations of extratropical patterns of atmospheric variability (e.g., Horel and Wallace 1982; Renwick and Wallace 1996; Kumar and Hoerling 1998; Newman and Sardeshmukh 1998; Wallace 2000; Ambaum et al. 2001; Giannini et al. 2001; Hastenrath and Greischar 2001; Ostermeier and Wallace 2003).”
Midlatitude Excitation of Tropical Variability in the Pacific: The Role of Thermodynamic Coupling and Seasonality* (2009, background): “For reference, the NPO is related to the west Pacific teleconnection pattern at upper levels and involves a meridional shift in the climatological jet location (Hsu and Wallace 1985; Linkin and Nigam 2008), and the Aleutian low is related to the Pacific–North America teleconnection pattern (Wallace ”
The summertime annular mode in the Northern Hemisphere and its linkage to the winter mode (2004, background): “Even for the original AO/NAM, there is debate on this issue [Ambaum et al., 2001; Itoh, 2002; Wallace, 2000; Wallace and Thompson, 2002].”
Review article. Studying climate effects on ecology through the use of climate indices: the North Atlantic Oscillation, El Niño Southern Oscillation and beyond (2003, background): “Trenberth 1997; Wallace 2000) or even their actual existence (e.g. Deser 2000; Ambaum et al. 2001), it is difficult for ecologists to assess their merit.”
Empirical Orthogonal Functions: The Medium is the Message (2009, background): “A simple illustrative example of the general inability of EOFs to separate localized structures was presented in Ambaum et al. (2001).”
