Stratospheric Forcing of Surface Climate in the Arctic Oscillation (2002, methodology): “For consistency with Thompson and Wallace (2000), the AO patterns presented in Figs.”
The dynamics of NAO teleconnection pattern growth and decay (2003, background): “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).”
In search of simple structures in climate: simplifying EOFs (2006, background): “It corresponds to the familiar AO pattern (Thompson and Wallace, 1998, 2000; Wallace, 2000, Wallace and Thompson, 2002).”
Arctic Oscillation or North Atlantic Oscillation (2001, background): “The importance of the distinction between NAO and AO has been highlighted by Wallace (2000).”
On the existence of multiple climate regimes (2004, background): “An interesting example of this is provided by the ongoing debate over the physical meaning of the Arctic oscillation leading sea-level pressure EOF (e.g. Wallace 2000; Ambaum et al. 2001, 2002; Wallace and Thompson 2002).”
Zonal Jet Structure and the Leading Mode of Variability (2007, unknown): “…Mode as the leading empirical orthogonal function of winter monthly mean 1000-hPa geopotential height [via sea level pressure (SLP) data] poleward of 20°N. Wallace (2000) then demonstrated that the leading EOF of the zonal-mean zonal wind is basically the same as the traditional annular mode.”
A Mechanism and Simple Dynamical Model of the North Atlantic Oscillation and Annular Modes (2004, background): “This spatial structure has been the object of much study and debate, going back at least as far as Walker and Bliss (1932), and summarized recently by Wallace (2000) and Wanner et al. (2002).”
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): “Whereas the debate over the NAO versus the NAM paradigm is of some interest to ecologists (see Aanes et al. 2002), it should be recognized that the distinction primarily has implications for interpreting the underlying dynamical mechanisms that give rise to NAO/NAM fluctuations ( Wallace 2000 ).”
Wave-Maintained Annular Modes of Climate Variability* (2000, methodology): “Recent observations demonstrate that month-tomonth tropospheric variation in the Northern Hemisphere is dominated by a mode that has a strong zonally symmetric or annular component (Baldwin and Dunkerton 1999; Thompson and Wallace 1998, 2000, hereafter TW).”
Spatial and temporal patterns of problem polar bears in Churchill, Manitoba (2009, background): “The NAO index is the mean deviation from the average sea level pressure between Iceland and the Azores, whereas the AO index is the mean deviation from the average sea level pressure throughout the Northern Hemisphere, north of 20N ( Wallace 2000 ).”
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.”
Solar cycle modulation of the North Atlantic Oscillation: Implication in the spatial structure of the NAO (2002, background): “With the exception of the Pacific sector, the horizontal and vertical structure of type P is very similar to that associated with the NAM [cf. Figures 3 and 4 with Figures 6 and 7 of Thompson and Wallace, 2000].”
Empirical Orthogonal Functions: The Medium is the Message (2009, background): “While the debate regarding the degree of zonal localization of extratropical atmospheric variability remains open (e.g., Wallace 2000; Vallis and Gerber 2008), this example clearly illustrates the fact that the presence of large-scale structures in a particular EOF pattern is not sufficient…”
Nonstationary influence of the North Atlantic Oscillation on European precipitation (2008, background): “Wallace [2000] concluded that stationbased indices do not provide an optimal representation of the NAO because of seasonal displacement of the Iceland low and the Azores anticyclone.”
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).”
The Effects of North Atlantic SST and Sea Ice Anomalies on the Winter Circulation in CCM3. Part II: Direct and Indirect Components of the Response (2004, background): “In addition, these responses resemble the model’s leading mode of internal variability, the simulated equivalent of the observed North Atlantic Oscillation or Northern Hemisphere annular mode patterns (e.g., Wallace 2000 ).”
Annular Modes in the Extratropical Circulation. Part II: Trends (2000, background): “The NAO and the AO are different representations and conceptual interpretations of the same phenomenon (Kerr 1999; Wallace 2000).”
Multilevel Regression Modeling of Nonlinear Processes: Derivation and Applications to Climatic Variability (2005, background): “It corresponds to the lowindex phase of the well-known Arctic Oscillation (AO; Deser 2000; Wallace 2000).”
