• Early Pliocene increase in thermohaline overturning: A precondition for the development of the modern equatorial Pacific cold tongue (2010, background): “…Ma led to a global decrease in tropical TCD. [45] A recent analysis of IPCC model results examining the next 100 years indicates a thermodynamically driven weakening of the Walker circulation in response to global warming, possibly favoring El Niño–like climate conditions [Vecchi and Soden, 2007].”
• Equilibrium Response of an Atmosphere–Mixed Layer Ocean Model to Different Radiative Forcing Agents: Global and Zonal Mean Response (2008, methodology): “Note that qualitatively similar changes in the vertical motion were reported for all IPCC AR4 models under the Special Report on Emissions Scenarios (SRES) A1B scenario by Held and Soden (2006) and Vecchi and Soden (2007).”
• Why is the amplitude of the Indian Ocean Dipole overly large in CMIP3 and CMIP5 climate models? (2013, methodology): “Climate model experiments participating in CMIP3 have been used to address such issues, and the consensus that emerges shows a mean state change with a shoaling thermocline and slower subsurface warming in the eastern Indian Ocean compared to the west [Vecchi and Soden, 2007].”
• Expansion of the Hadley cell under global warming (2007, background): “Such a slowdown seems to be a robust feature in GCMs [Vecchi and Soden, 2007], and has been identified in observational analyses of the Walker”
• Narrowing of the ITCZ in a warming climate: Physical mechanisms (2016, background): “…the location of the ITCZ [e.g., Philander et al., 1996; Kang et al., 2008; Schneider et al., 2014] and the strength of the vertical motion within the ITCZ [e.g., Schneider, 2006; Vecchi and Soden, 2007; Schneider et al., 2010; Bony et al., 2013; Bellomo and Clement, 2015] to changes in climate.”
• Solar cycle signals in sea level pressure and sea surface temperature (2010, background): “The latter also include additional in situ observations from the UK Meteorological Office archive which are not included in the former (Vecchi and Soden, 2007).”
• WATER VAPOR AND THE DYNAMICS OF CLIMATE CHANGES (2009, methodology): “The gross upward mass flux decreases more slowly than the water vapor cycling rate in almost all models used in the IPCC Fourth Assessment Report [Vecchi and Soden, 2007].”
• Stratospheric geoengineering impacts on El Niño/Southern Oscillation (2015, background): “The period of time required to robustly detect and attribute changes in the tropical Pacific Walker Circulation is found to be up to 130 years (Vecchi et al., 2006; Vecchi and Soden, 2007) and no less than 60 years (Tokinaga et al.”
• Why is longwave cloud feedback positive (2010, result): “This reduction in clear‐ sky w is consistent with several other studies that have pointed out the robust slowdown of the tropical circulation in a warmer climate [Knutson and Manabe, 1995; Held and Soden, 2006; Vecchi and Soden, 2007; Gastineau et al., 2009].”
• Observational Evidence That Enhanced Subsidence Reduces Subtropical Marine Boundary Layer Cloudiness (2013, background): “Models currently predict that inversion strength over eastern subtropical oceans will increase, while subsidence will weaken (Held and Soden 2006; Vecchi and Soden 2007; Webb et al. 2013).”
• Scaling of Precipitation Extremes over a Wide Range of Climates Simulated with an Idealized GCM (2009, background): “found in global warming simulations (Held and Soden 2006; Vecchi et al. 2006; Vecchi and Soden 2007).”
• Origins of differences in climate sensitivity, forcing and feedback in climate models (2013, background): “7f), as expected given the established weakening of the Walker Circulation with increasing temperatures (Vecchi and Soden 2007).”
