Atmospheric component of the MPI‐M Earth System Model: ECHAM6 (2013, background): “The extratropical jets maximize at somewhat lower latitudes than observed (see also Kidston and Gerber [2010] who document similar biases in the family of CMIP3 models), particularly in the southern hemisphere during austral summer.”
Impact of stratospheric ozone on Southern Hemisphere circulation change: A multimodel assessment (2010, background): “A similar relationship between climatology and climate response to external forcing, however, has also been identified for different external forcings in both idealized [ Simpson et al. , 2010] and comprehensive GCMs [ Kidston and Gerber , 2010].”
Connections Between Clouds, Radiation, and Midlatitude Dynamics: a Review (2015, background): “While a substantial fraction of this uncertainty is related to dynamical biases [44], there is increasing evidence that cloud processes also contribute to the spread in the dynamical response.”
Assessing and understanding the impact of stratospheric dynamics and variability on the earth system (2012, background): “A similar connection between jet shifts and climatological jet position was found in CMIP3 models (Kidston and Gerber 2010).”
Future climate change in the Southern Hemisphere: Competing effects of ozone and greenhouse gases (2011, result): “[16] These results complement recent findings that biases in the climatological SH jet position [Kidston and Gerber, 2010] and energy budget [Trenberth and Fasullo, 2010] are related to the magnitude of future shifts in the jet and”
The relationship between the ITCZ and the Southern Hemispheric eddy‐driven jet (2013, background): “…the current global warming trend is projected to cause a detectable poleward shift of the westerlies, particularly in the SH [Kushner et al., 2001; Kidston and Gerber, 2010; Barnes and Polvani, 2013], it may also induce a change in the interhemispheric thermal gradient, due to faster warming in…”
Response of the large‐scale structure of the atmosphere to global warming (2015, background): “A good correlation between the climatological jet latitude and its shift, in austral summer, was found by Kidston and Gerber (2010), and it may be that a more detailed examination of seasonal effects in individual models is needed to fully understand the results.”
A Diagnosis of the Seasonally and Longitudinally Varying Midlatitude Circulation Response to Global Warming (2014, methodology): “…using various metrics including 1) simple metrics of the climatological zonal-mean or basin-mean jet location (e.g., Fyfe and Saenko 2006; Kidston and Gerber 2010; Swart and Fyfe 2012; Wilcox et al. 2012; Woollings and Blackburn 2012; Barnes and Polvani 2013; Bracegirdle et al. 2013), 2)…”
Extreme moisture transport into the Arctic linked to Rossby wave breaking (2014, background): “In addition, the latitude of the eddy-driven jet over the North Atlantic in climate models exhibits an equatorward bias [e.g., Kidston and Gerber, 2010; Barnes and Polvani, 2013], similar to a negative NAO state.”
High Resolution Model Intercomparison Project (HighResMIP v1.0) for CMIP6 (2016, background): “This behaviour may partly explain the dominant equatorward bias of the jet stream in generations of global climate simulations with model resolutions much coarser than 50 km (Kidston and Gerber, 2010; Barnes and Polvani, 2013; Lu et al., 2015).”
An Evaluation of the Large‐Scale Atmospheric Circulation and Its Variability in CESM2 and Other CMIP Models (2020, background): “Indeed, in support of this viewpoint, Kidston and Gerber (2010) argued that CMIP3 models with a more persistent SAM also exhibited a larger response to GHG forcing.”
