A Spatial Evaluation of Arctic Sea Ice and Regional Limitations in CMIP6 Historical Simulations

LEE, JACLYN CLEMENT KINNEY, AND b ROBERT OSINSKI a Department of Oceanography, Naval Postgraduate School, Monterey, California b Institute of Oceanology of Polish Academy of Sciences, Sopot, Poland (Manuscript received 29 June 2020, in final form 28 April 2021) ABSTRACT: The Arctic sea ice response to a warming climate is assessed in a subset of models participating in phase 6 of the Coupled Model Intercomparison Project (CMIP6), using several metrics in comparison with satellite observations and results from the Pan-Arctic Ice Ocean Modeling and Assimilation System and the Regional Arctic System Model. Our study examines the historical representation of sea ice extent, volume, and thickness using spatial analysis metrics, such as the integrated ice edge error, Brier score, and spatial probability score. We find that the CMIP6 multimodel mean captures the mean annual cycle and 1979–2014 sea ice trends remarkably well. However, individual models experience a wide range of uncertainty in the spatial distribution of sea ice when compared against satellite measurements and reanalysis data. Our metrics expose common and individual regional model biases, which sea ice temporal analyses alone do not capture. We identify large ice edge and ice thickness errors in Arctic subregions, implying possible model specific limitations in or lack of representation of some key physical processes. We postulate that many of them could be related to the oceanic forcing, especially in the marginal and shelf seas, where seasonal sea ice changes are not adequately simulated. -

Some Aspects of the Thermal Energy Exchange on the South Polar Snow Field and Arctic Ice Pack'
MAY 1961 MONTHLY WEATHER REVIEW 173 SOME ASPECTS OF THE THERMAL ENERGY EXCHANGE ON THE SOUTH POLAR SNOW FIELD AND ARCTIC ICE PACK' KIRBY J. HANSON Po!ar Meteorology Research Project, US. Weather Bureau, Washington, D.C. [Manuscript received September 13, 1960; revised February 21, 1961 ] ABSTRACT Solar and terrestrial radiation measurements that were obtained at Amundsen-Scot>t (South Pole) Station and on Ice lsland (Bravo) T-3 are presented for representative summer and winter months. Of the South Polar net radiation loss during April 1958, approximately20 percent of the energy came from the snow and80 percent from the air. The actual atmospheric cooling rate during that period was only about lj6 of the suggested radiative cooling rate. The annual net radiation at various places in Antarctica is presented. During 1058, the South Polar atmos- phere transmitted about 73 percent of the annual extraterrestrial radiation, while at T-3 the Arctic atmosphere transmitted about 56 percent. The albedo of melting sea ice is discussed. Measurements on T-3 during July 1958 indicate that the net radiation is positive on both clear and overcast days but greatest on overcast days. Refreezing of the surface with clear skies, as observed by Untersteiner and Badglep, is discussed. 1.

MARCH 1999 VAVRUS 873 The Response of the Coupled Arctic Sea Ice±Atmosphere System to Orbital Forcing and Ice Motion at 6 kyr and 115 kyr BP STEPHEN J. VAVRUS Center for Climatic Research, Institute for Environmental Studies, University of WisconsinÐMadison, Madison, Wisconsin (Manuscript received 2 February 1998, in ®nal form 11 May 1998) ABSTRACT A coupled atmosphere±mixed layer ocean GCM (GENESIS2) is forced with altered orbital boundary conditions for paleoclimates warmer than modern (6 kyr BP) and colder than modern (115 kyr BP) in the high-latitude Northern Hemisphere. A pair of experiments is run for each paleoclimate, one with sea-ice dynamics and one without, to determine the climatic effect of ice motion and to estimate the climatic changes at these times. At 6 kyr BP the central Arctic ice pack thins by about 0.5 m and the atmosphere warms by 0.7 K in the experiment with dynamic ice. At 115 kyr BP the central Arctic sea ice in the dynamical version thickens by 2±3 m, accompanied bya2Kcooling. The magnitude of these mean-annual simulated changes is smaller than that implied by paleoenvironmental evidence, suggesting that changes in other earth system components are needed to produce realistic simulations. Contrary to previous simulations without atmospheric feedbacks, the sign of the dynamic sea-ice feedback is complicated and depends on the region, the climatic variable, and the sign of the forcing perturbation. Within the central Arctic, sea-ice motion signi®cantly reduces the amount of ice thickening at 115 kyr BP and thinning at 6 kyr BP, thus serving as a strong negative feedback in both pairs of simulations.
