متن کاملWhat Controls the Strength of Snow-Albedo Feedback?
The strength of snow-albedo feedback (SAF) in transient climate change simulations of the Fourth Assessment of the Intergovernmental Panel on Climate Change is generally determined by the surfacealbedo decrease associated with a loss of snow cover rather than the reduction in snow albedo due to snow metamorphosis in a warming climate. The large intermodel spread in SAF strength is likewise attr...
متن کاملAssessing Snow Albedo Feedback in Simulated Climate Change
We isolate and quantify the two factors controlling Northern Hemisphere springtime snow albedo feedback in transient climate change based on scenario runs of 17 climate models used in the IPCC 4th Assessment. The first factor is the dependence of planetary albedo on surface albedo, representing the atmosphere’s attenuation effect on surface albedo anomalies. It is potentially a major source of ...
متن کاملOn the Persistent Spread in Snow - Albedo Feedback
Snow-albedo feedback (SAF) is examined in 25 climate change simulations 5 participating in the Coupled Model Intercomparison Project version 5 (CMIP5). SAF 6 behavior is compared to the feedback’s behavior in the previous (CMIP3) generation of 7 global models. SAF strength exhibits a fivefold spread across CMIP5 models, ranging 8 from 0.03 to 0.16 W m−2 K−1 (ensemble-mean = 0.08 W m−2 K−1). Thi...
متن کاملVegetation controls on northern high latitude snow-albedo feedback: observations and CMIP5 model simulations.
The snow-masking effect of vegetation exerts strong control on albedo in northern high latitude ecosystems. Large-scale changes in the distribution and stature of vegetation in this region will thus have important feedbacks to climate. The snow-albedo feedback is controlled largely by the contrast between snow-covered and snow-free albedo (Δα), which influences predictions of future warming in ...
