A Fair Assessment of Sea Ice Age Reduces Bias and Gives New Insight to Arctic Sea Ice Dynamics Open
The rapid Arctic warming in the early 2000s triggered a tremendous loss of multi‐year sea ice. Since then, sea ice age has been largely overlooked, despite its value in evaluating climate model skill in capturing sea ice dynamics. Comparin…

Impact of modulating surface heat flux through sea ice leads on Arctic sea ice in EC-Earth3 in different climates Open
This sensitivity study examines the impact of modulating surface sensible heat flux over leads – open-water areas within sea ice cover – to approximate finer-scale processes that are often underrepresented in climate models. We aim to asse…

Which Climate Model Evaluation Methods Can Consistently Select Skillful Models from the CMIP6 Ensemble? Open
When considering the possible use of climate model data, it is necessary to choose which model is most appropriate to use. There are many methods for evaluating and selecting climate models in the literature, but there is no established co…

Warming and freshening coastal waters impact harmful algal bloom frequency in high latitudes Open
Harmful algal blooms contaminate seafood with toxins and poison humans and wildlife upon consumption. Toxic algae niches are projected to expand in high latitudes, but how the frequency of their blooms will evolve is still little known. He…

Arctic‐Atlantic Cyclones: Variability in Thermodynamic Characteristics, Large‐Scale Flow, and Local Impacts Open
Cyclones at polar latitudes of the Atlantic‐Arctic corridor exhibit different thermodynamic characteristics. Midlatitude‐origin cyclones, which make up about 14% of wintertime cyclones in the region, are generally warm and moist. The more …

The next generation sea-ice model neXtSIM, version 2 Open
While many large-scale sea ice models can represent regional to global sea ice evolution, their representation of sea ice dynamics varies little between models. This is because they all use rheologies based on the hypothesis that sea ice b…

Modulating surface heat flux through sea ice leads improves Arctic sea ice simulation in the coupled EC-Earth3 Open
In this study, we address a persistent positive bias in Arctic sea ice (concentration and thickness) in the global climate model EC-Earth3 (ECE3) by including a modulating factor to the surface sensible heat flux over regions with sea ice …

Changes in the North Atlantic Oscillation over the 20th century Open
The North Atlantic Oscillation explains a large fraction of the climate variability across the North Atlantic from the eastern seaboard of North America across the whole of Europe. Many studies have linked the North Atlantic Oscillation to…

Breaking the Ice: Exploring the Changing Dynamics of Winter Breakup Events in the Beaufort Sea Open
The Beaufort Sea has experienced a significant decline in sea ice, with thinner first‐year ice replacing thicker multi‐year ice. This transition makes the ice cover weaker and more mobile, making it more vulnerable to breakup during winter…

Multi-platform high resolution in situ observations for understanding mesoscale and sub-mesoscale processes and their role in the air-sea exchanges: Experiences and prospects from the EUREC4A-OA/ATOMIC field experiment Open
In January-February 2020, the EUREC4A-OA/ATOMIC experiment took place in the Northwest Tropical Atlantic with the overall goal of understanding the role of fine-scale processes in internal ocean dynamics and air-sea interaction. Four ocean…

Super-resolution of satellite observations of sea ice thickness using diffusion models and physical modeling. Open
This work introduces a simulator of high-resolution sea ice thickness in the Arctic based on diffusion models, which is a type of artificial intelligence (AI) generative model. Diffusion models have already shown impressive skill in genera…

Reducing biases in low cloud cover over the tropical Atlantic in the Norwegian Earth System Model Open
Biases in the representation of low cloud cover in climate models has been identified as one of the leading causes of uncertainty in equilibrium climate sensitivity. It is therfore crucial to reduce current climate model biases in low clou…

Arctic amplification has already peaked Open
It has been demonstrated that the Arctic has warmed at almost four times the global average rate since 1979, a phenomenon known as Arctic amplification. However, this rapid Arctic warming is tightly linked to the retreat and thinning of su…

Driving Mechanisms of an Extreme Winter Sea Ice Breakup Event in the Beaufort Sea Open
The loss of thick multiyear sea ice in the Arctic leads to weaker sea ice that is more easily broken up by strong winds. As a consequence, extreme sea ice breakup events may become more frequent, even during the middle of winter when the s…

Slab to back-arc to arc: fluid and melt pathways through the mantle wedge beneath the Lesser Antilles Open
Volatiles expelled from subducted plates promote melting of the overlying warm mantle, feeding arc volcanism. However, debates continue over the factors controlling melt generation and transport and how these determine the placement of vol…

The thermodynamic differences between winter cyclones from midlatitudes and high latitudes Open
Cyclones carry heat and moisture that impact local conditions along their path. Cyclones with different origins can, however, have different life cycles and cause different impacts. To quantify differences in the thermodynamic evolution of…

Driving Mechanisms of an Extreme Winter Sea Ice Breakup Event in the Beaufort Sea Open
The thick multiyear sea ice that once covered large parts of the Arctic is increasingly being replaced by thinner and weaker first‐year ice, making it more vulnerable to breakup by winds. We use the neXtSIM sea ice model to investigate the…
