Abstract. We compare the mass budget of Arctic sea ice for 15 models submitted to latest Coupled Model Intercomparison Project (CMIP6), using new diagnostics that have not been available previous model inter-comparisons. These allow us look beyond standard metrics cover and thickness processes growth loss in climate a more detailed way than has previously possible. For 1960–1989 multi-model mean, dominant causing annual are basal frazil formation, which both occur during winter. The main by...

We compare the mass budget of Arctic sea ice for 14 models submitted to latest Climate Model Inter-comparison Project (CMIP6), using new diagnostics that have not been available previous model inter-comparisons. Using these allows us look beyond standard metrics cover and thickness, processes growth loss in climate a more detailed way than has previously possible.

Abstract. The retreat of Arctic sea ice is frequently considered to be a possible driver changes in climate extremes the and possibly down mid-latitudes. However, it remains unclear how atmosphere will respond near-total summer ice, reality that might occur foreseeable future. This study explores this question by conducting sensitivity experiments with two global coupled models run at different horizontal resolutions investigate change temperature precipitation during over peripheral regions...
Abstract The mid-latitude climate responses to Arctic sea ice loss remain unclear, partly because the atmospheric depend sensitively location of anomalies. Evaluating role regional extent anomalies is therefore essential appreciate responses. We investigated these but also precursors in long pre-industrial control simulations from 36 CMIP6 models. This study examines changes various variables at different lead and lag times by performing a composite analysis between years low high extents...
This study investigates the differences in atmospheric responses to Arctic sea ice anomalies between simulations from six (atmospheric-only) models contributing Polar Amplification Model Intercomparison Project and one long control simulation (piControl CMIP6) same (coupled) models. We perform a composite analysis years of low high extent piControl consider four different types experiment PAMIP where only concentration is changed (pdSST-futArcSIC, pdSST-futBKSeasSIC, pdSST-futOkhotskSIC...
Abstract. The atmospheric circulation response to Arctic sea ice loss may differ depending on the region of but also methodology used study this impact. Examining different possible responses is essential, as not melting uniformly. In study, we examine in winter regional using two approaches across seven climate models. anomaly areas are pan-Arctic, Barents-Kara Seas only, and Sea Okhotsk only. first approach involves sensitivity experiments performed within Polar Amplification Model...

<p>In this work, we make use of an inter-model comparison and a perfect model approach, in which outputs are used as true reference states, to assess the impact that denying sea ice information has on prediction atmospheric processes, both over Arctic at mid-latitude regions. To do so, two long-term control runs (longer than 250 years) were generated with state-of-the-art General Circulation Models (GCM), namely EC-Earth HadGEM. From these have identified three different years...
<p>The retreat of Arctic sea ice for the last four decades is a primary manifestation climate system response to increasing atmospheric greenhouse gas concentrations. This frequently considered as possible driver circulation anomalies at mid-latitudes. However, year-to-year evolution cover also characterized by significant fluctuations attributed internal variability. It unclear how atmosphere will respond near-total summer ice, reality that might occur in foreseeable future....
