The Role of Eddies in Driving the Tropospheric Response to Stratospheric Heating Perturbations (2009, background): “(2007), who showed the importance of a change in phase speed in the poleward shift of midlatitude westerlies in response to a change in surface friction, Chen and Held (2007) have suggested that a similar mechanism could produce a tropospheric response to stratospheric zonal wind anomalies.”
The predictability of the extratropical stratosphere on monthly time‐scales and its impact on the skill of tropospheric forecasts (2015, background): “These are mostly related to the so-called index of refraction for Rossby waves (Matsuno, 1970), and include: • influences on eddy phase speed (Chen and Held, 2007); • influences on eddy length scales (Kidston et al., 2010; Rivière, 2011); • changes to the index of refraction for baroclinic…”
The Steady-State Atmospheric Circulation Response to Climate Change–like Thermal Forcings in a Simple General Circulation Model (2010, methodology): “4 days as per the error estimate given in Gerber et al. 2008) for equinoctial conditions, which is comparable to the time scale of the observed annularmodes (;10–20 days) and is close to the benchmark range proposed by Gerber et al. (2008). As mentioned in section 4, the time scale of the annular mo”
A Dynamical Interpretation of the Poleward Shift of the Jet Streams in Global Warming Scenarios (2011, methodology): “A few studies (Orlanski 2003; Rivière and Orlanski 2007; Laı̂né et al. 2011) indicate that the increase in humidity favors the occurrence of cyclonic wave-breaking (CWB or LC2) events to the detriment of anticyclonic wave-breaking (AWB or LC1) events. As explained by Orlanski (2003), more latent hea”

Impact of stratospheric ozone on Southern Hemisphere circulation change: A multimodel assessment (2010, background): “on the poleward side of the climatological jet, which is often described as a positive trend in the annular modes [Thompson et al., 2000; Chen and Held, 2007], and the poleward”
The relationship between the ITCZ and the Southern Hemispheric eddy‐driven jet (2013, background): “In the context of anthropogenic climate change, the effect of global warming on the latitude of the eddy-driven jet has received much attention in the recent literature [e.g., Hartmann et al., 2000; Kushner et al., 2001; Chen and Held, 2007; Lorenz and DeWeaver, 2007; Kidston et al., 2011].”
WATER VAPOR AND THE DYNAMICS OF CLIMATE CHANGES (2009, background): “(In addition to the mechanisms sketched here, the width of the Hadley circulation may also change in response to changes in upper tropospheric wave dynamics that may be caused by lower stratospheric changes associated with ozone depletion or increased concentrations of greenhouse gases [Chen and Hel”
Phase Speed Spectra and the Latitude of Surface Westerlies: Interannual Variability and Global Warming Trend (2008, background): “…winds may accelerate the eastward phase speeds of midlatitude eddies, resulting in a poleward shift of the eddy momentum flux convergence and the associated surface winds, analogous to the interpretations for the positive annular trend due to stratospheric ozone depletion (Chen and Held 2007).”
