A Data Set for intercomparing the transient behavior of dynamical model-based subseasonal to decadal climate predictions
(American Geophysical Union, 2021)
Article
Open AccessClimate predictions using coupled models in different time scales, from intraseasonal to decadal, are usually affected by initial shocks, drifts, and biases, which reduce the prediction skill. These arise from inconsistencies ... -
An anatomy of Arctic sea ice forecast biases in the seasonal prediction system with EC-Earth
(Springer Link, 2021)
Article
Open AccessThe quality of initial conditions (ICs) in climate predictions controls the level of skill. Both the use of the latest high-quality observations and of the most efficient assimilation method are of paramount importance. ... -
An assessment of regional sea ice predictability in the Arctic ocean
(Springer, 2019-07)
Article
Open AccessArctic sea ice plays a central role in the Earth’s climate. Changes in the sea ice on seasonal-to-interannual timescales impact ecosystems, populations and a growing number of stakeholders. A prerequisite for achieving ... -
An assessment of regional sea ice predictability in the Arctic ocean

An assessment of ten ocean reanalyses in the polar regions
(Springer, 2019-02)
Article
Open AccessGlobal and regional ocean and sea ice reanalysis products (ORAs) are increasingly used in polar research, but their quality remains to be systematically assessed. To address this, the Polar ORA Intercomparison Project ... -
Arctic sea-ice change tied to its mean state through thermodynamic processes
(Nature Publishing Group, 2018-06-18)
Article
Open AccessOne of the clearest manifestations of ongoing global climate change is the dramatic retreat and thinning of the Arctic sea-ice cover. While all state-of-the-art climate models consistently reproduce the sign of these ... -
Benefits of Increasing the Model Resolution for the Seasonal Forecast Quality in EC-Earth
(American Meteorological Society, 2016-12-05)
Article
Open AccessResolution in climate models is thought to be an important factor for advancing seasonal prediction capability. To test this hypothesis, seasonal ensemble reforecasts are conducted over 1993–2009 with the European community ... -
Earth System Model Evaluation Tool (ESMValTool) v2.0 – an extended set of large-scale diagnostics for quasi-operational and comprehensive evaluation of Earth system models in CMIP
(Copernicus Publications, 2020)
Article
Open AccessThe Earth System Model Evaluation Tool (ESMValTool) is a community diagnostics and performance metrics tool designed to improve comprehensive and routine evaluation of Earth system models (ESMs) participating in the Coupled ... -
Impact of the ice thickness distribution discretization on the sea ice concentration variability in the NEMO3.6–LIM3 global ocean–sea ice model
(Copernicus Publications, 2020-10-05)
Article
Open AccessThis study assesses the impact of different sea ice thickness distribution (ITD) discretizations on the sea ice concentration (SIC) variability in ocean stand-alone NEMO3.6–LIM3 simulations. Three ITD discretizations with ... -
Improving Arctic weather and seasonal climate prediction: recommendations for future forecast systems evolution from the European project APPLICATE
(2022-10)
Article
Open AccessThe Arctic environment is changing, increasing the vulnerability of local communities and ecosystems, and impacting its socio-economic landscape. In this context, weather and climate prediction systems can be powerful tools ... -
Link between autumnal Arctic Sea ice and Northern Hemisphere winter forecast skill
(American Geophysical Union (AGU), 2020-02-28)
Article
Open AccessDynamical forecast systems have low to moderate skill in continental winter predictions in the extratropics. Here we assess the multimodel predictive skill over Northern Hemisphere high latitudes and midlatitudes using ... -
Making seasonal outlooks of Arctic Sea ice and Atlantic hurricanes valuable—not just skillful
(American Meteorological Society, 2020-01)
Article
Open AccessIn recent years, a big effort has been made by part of the climate community toward the development of climate services in order to make climate information decision oriented. In a climate forecasting context, this means ... -
On the discretization of the ice thickness distribution in the NEMO3.6-LIM3 global ocean–sea ice model
(European Geosciences Union (EGU), 2019-08-27)
Article
Open AccessThe ice thickness distribution (ITD) is one of the core constituents of modern sea ice models. The ITD accounts for the unresolved spatial variability of sea ice thickness within each model grid cell. While there is a ... -
Quantifying climate feedbacks in polar regions
(Nature Publishing Group, 2018-05-15)
Article
Open AccessThe concept of feedback is key in assessing whether a perturbation to a system is amplified or damped by mechanisms internal to the system. In polar regions, climate dynamics are controlled by both radiative and non-radiative ... -

Record low northern hemisphere sea ice extent in March 2015
(American Meteorological Society, 2016-12-01)
Article
Open AccessThe record low Northern Hemisphere (NH) winter sea ice maximum stemmed from a strong interannual surface anomaly in the Pacific sector, but it would not have been reached without long-term climate change. -
Relationships between Arctic sea ice drift and strength modelled by NEMO-LIM3.6
(European Geosciences Union (EGU), 2017-12-11)
Article
Open AccessSea ice cover and thickness have substantially decreased in the Arctic Ocean since the beginning of the satellite era. As a result, sea ice strength has been reduced, allowing more deformation and fracturing and leading ... -
