Global characterization of the Holocene Thermal Maximum (2012, background): “Furthermore, previous idealized modelling studies with uniform forcing have indicated that enhanced meridional transport of latent heat in a warmer atmosphere also contributes to polar amplification (e.g., Alexeev et al., 2005; Langen and Alexeev, 2007).”
Polar Amplification in CCSM4: Contributions from the Lapse Rate and Surface Albedo Feedbacks (2014, background): “point in the opposite direction (Alexeev et al. 2005; Langen andAlexeev 2007; Graversen et al. 2008).”
The dependence of transient climate sensitivity and radiative feedbacks on the spatial pattern of ocean heat uptake (2014, result): “This is consistent with the polar-amplified179 warming pattern [Alexeev et al., 2005].180 Fig.2g-i show estimates of the net local feedback λ(φ) in CAM4, along with its break-181 down into LW and SW clear and (residual) cloud-sky components (the clear-sky SW182 component is positive but less than…”
Land–Ocean Warming Contrast over a Wide Range of Climates: Convective Quasi-Equilibrium Theory and Idealized Simulations (2013, background): “Although the idealized GCM does not include many of these processes, it still shows a polarampliﬁcation effectunder climate change(O’Gorman and Schneider 2008a; see also Alexeev et al. 2005).”
Simulated Antarctic precipitation and surface mass balance at the end of the twentieth and twenty-first centuries (2006, background): “It has been shown to be due to a general increase of poleward heat transport with increasing global mean temperature (Alexeev et al. 2005), with further amplification through local feedbacks (Holland and Bitz 2003).”
How Well Do We Understand and Evaluate Climate Change Feedback Processes (2006, methodology): “In idealized box models such as those developed by Pierrehumbert (1995) or Larson et al. (1999), the circulation is idealized even further by partitioning the Tropics into a single moist, precipitating area covered by convective clouds and a single dry, nonprecipitating area associated with sinking ”
Arctic warming, increasing snow cover and widespread boreal winter cooling (2012, background): “…attribute much of this warming to rapid increases in greenhouse gases (GHGs) and project the strongest warming across the extratropical NH during boreal winter due to ‘winter (or Arctic) amplification’ (Holland and Bitz 2003, Hansen and Nazarenko 2004, Alexeev et al 2005, Langen and Alexeev 2007).”
Coupling between Arctic feedbacks and changes in poleward energy transport (2011, background): “In terms of energy transport, increasing moisture transport in a warmer climate was found to be responsible for enhanced Arctic warming in idealized experiments without surface albedo feedback [Hall, 2004; Alexeev et al., 2005; Graversen and Wang, 2009].”
Arctic amplification enhanced by latent energy transport of atmospheric planetary waves (2016, methodology): “For example, the enhancement of the downwelling long-wave radiation associated with a persistent positive change of the latent energy transport may lead to sea-ice and snowmelt hereby augmenting the surfacealbedo feedback (Alexeev et al., 2005; Kapsch et al., 2013).”
Polar amplification in a coupled climate model with locked albedo (2009, methodology): “Hence, these experiments, which are performed using a state-of-the-art coupled model, confirm what has previously been found from experiments with models of less complexity: a polar amplification of the SAT field cannot be explained by the SAF alone (Hall 2004; Alexeev et al. 2005; Langen and Alexee”
