• Robust increase in equilibrium climate sensitivity under global warming (2013, background): “The leading hypothesis is that this nonlinearity is related to the spatial distribution of surface warming which is initially dampened at high latitudes due to regional ocean heat uptake [Winton et al., 2010].”
• Climate and carbon cycle changes from 1850 to 2100 in MPI‐ESM simulations for the Coupled Model Intercomparison Project phase 5 (2013, background): “Possible explanations include decadal time scale adjustments of the ocean circulation, differential warming patterns for example associated with ocean heat uptake, or state dependencies of the radiative feedback factors [Senior and Mitchell, 2000; Winton et al., 2010; Block and Mauritsen, 2013].”
• The dependence of transient climate sensitivity and radiative feedbacks on the spatial pattern of ocean heat uptake (2014, background): “…of OHU in setting transient climate sensitivity.25 However, observations [Yu and Weller , 2007] and coupled general circulation model26 (GCM) simulations [Winton et al., 2010; Bitz et al., 2012] suggest that the geographic27 pattern of OHU is far from uniform or steady (see auxiliary material).”
• Earth's energy imbalance and implications (2011, background): “Held et al. (2010) and Winton et al. (2010) draw attention to and analyze two distinct time scales in the climate response, a quick partial climate response with characteristic time about 5 yr and a slow warming on century time scales, which they term the “recalcitrant” component of the climate…”
• Transient Climate Response in a Two-Layer Energy-Balance Model. Part I: Analytical Solution and Parameter Calibration Using CMIP5 AOGCM Experiments (2013, methodology): “In this formulation of the radiative imbalance N , the assumption of linear dependency in T suffers from some limitations (Gregory et al. 2004; Williams et al. 2008; Winton et al. 2010; Held et al. 2010) that are addressed in Part II of this study (Geoffroy et al. 2013, hereafter Part II).”
• Transient Climate Response in a Two-Layer Energy-Balance Model. Part II: Representation of the Efficacy of Deep-Ocean Heat Uptake and Validation for CMIP5 AOGCMs (2013, methodology): “Introducing the normalized equilibrium temperature amplitude function r ieq 5T i eq/Teq, the local heat budget at equilibrium is F i 2 lirieqTeq1Aieq 1Ai0eq 5 0.”
• Maximum warming occurs about one decade after a carbon dioxide emission (2014, background): “Finally, there are uncertainties of thermal inertia in the climate system associated with the exchange of heat between the atmosphere and the surface and deep oceans which influences the timing of climate change (Winton et al 2010).”
• Forcing and feedback in the MPI‐ESM‐LR coupled model under abruptly quadrupled CO2 (2013, methodology): “…cause of the nonlinearity is a decadal adjustment associated with differential warming patterns of the ocean associated with deep ocean heat uptake [Winton et al., 2010], then one expects that the regressed feedback factors depend only on the time since the applied forcing, and not on the…”
• Evaluating Emergent Constraints on Equilibrium Climate Sensitivity (2018, background): “In particular, ECS estimates tend to increase as model runs are extended (Williams et al. 2008; Winton et al. 2010; Andrews et al. 2012, 2015).”
• The Dependence of Radiative Forcing and Feedback on Evolving Patterns of Surface Temperature Change in Climate Models (2015, methodology): “Winton et al. (2010), Held et al. (2010), and Geoffroy et al. (2013) used a two-layer ocean model (approximating a mixed layer and deep-ocean response) and an ‘‘ocean heat F IG .”
• Forcing, feedbacks and climate sensitivity in CMIP5 coupled atmosphere‐ocean climate models (2012, background): “We use four experiments: piControl (preindustrial fully-coupled control, run for hundreds of years), abrupt4xCO2 (as piControl but run for 150 years after instantaneous quadrupling of atmospheric CO2), sstClim (as piControl but run for 30 years with the ocean and sea-ice models replaced with climato”
• Climate Sensitivity of the Community Climate System Model, Version 4 (2012, background): “Winton et al. (2010) argues this is because different models respond differently to a given amount of ocean heat uptake.”
• Deep-ocean heat uptake and equilibrium climate response (2013, background): “Williams et al. (2008) and Winton et al. (2010) show that the spatial warming pattern changes as the climate evolves toward equilibrium because of the ocean heat uptake.”
