Dynamical feedbacks and the persistence of the NAO (2009, background): “Building from the work of LH03, Eichelberger and Hartmann (2007) studied the leading mode of variability for zonally averaged flow in the Atlantic and Pacific sectors during Northern Hemisphere winter.”
Key features of the IPSL ocean atmosphere model and its sensitivity to atmospheric resolution (2010, background): “An even stronger jet, as found in lower resolution simulations (not shown) will tend to trap eddies and destroy the positive feedback between eddies and jet fluctuations at the origin of the observed low-frequency variability (Eichelberger and Hartmann 2007).”
Variability of the North Atlantic eddy‐driven jet stream (2010, unknown): “This means that meridional wave propagation and the associated eddy momentum ﬂuxes are reduced (Eichelberger and Hartmann 2007).”
Empirical Orthogonal Functions: The Medium is the Message (2009, background): “In both observations and atmospheric GCMs, the leading EOF of extratropical zonal-mean zonal wind is a dipole with a central zero-crossing at approximately the mean latitude of the eddy-driven jet (e.g., Hartmann and Lo 1998; Codron 2005; Fyfe and Lorenz 2005; Eichelberger and Hartmann 2007).”
On the importance of midlatitude oceanic frontal zones for the mean state and dominant variability in the tropospheric circulation (2008, result): “Consequently, the annular mode becomes weaker and less well defined in its spatial structure in either hemisphere (Figure 4). Particularly, the winter mode is unrealistic, basically representing the STJ variability with no well-defined center of action in midlatitude [U] anomalies, consistent with ”
The relationship between the ITCZ and the Southern Hemispheric eddy‐driven jet (2013, background): “In turn, the subtropical jet interacts with the eddy-driven jet, due to its effects on baroclinicity [Lee and Kim, 2003; Brayshaw et al., 2008] and on barotropic wave propagation [Eichelberger and Hartmann, 2007; Barnes and Hartmann, 2011].”
Influence of the Tropics on the Southern Annular Mode (2012, background): “The subtropical jet driven by the Hadley circulation inhibits eddy feedback (Eichelberger and Hartmann 2007) but favors the generation of a Rossby wave source over its core region on a broad frequency band.”
Bidimensional Diagnostics, Variability, and Trends of Northern Hemisphere Blocking (2012, background): “Here eddies are trapped by the subtropical jet, suppressing meridional wave propagation and therefore reducing the presence of midlatitude Pacific blocking (Nakamura and Sampe 2002; Eichelberger and Hartmann 2007).”
