Accurately exchanging energy between the atmosphere and the ocean-ice systems through surface heat fluxes is crucial for climate modelling. We present an improved version of Coupled Arctic Prediction System (CAPS) by revising flux coupling for conservation of heat. Our results show that the model with improved flux coupling can better simulate sea ice conditions during the period of Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC).

Short summary
The sea ice thickness was simulated by a single-column model and compared with in situ observations obtained off Zhongshan Station in the Antarctic. It is shown that the unrealistic precipitation in the atmospheric forcing data leads to the largest bias in sea ice thickness and snow depth modeling. In addition, the increasing snow depth gradually inhibits the growth of sea ice associated with thermal blanketing by the snow.

Short summary
Using a newly developed atmosphere–ocean–wave–sea-ice model, we show that ocean waves affect Antarctic sea ice through indirect thermodynamics pathways. Wave-induced heat fluxes and Langmuir-enhanced mixing produce modest sea-ice and ocean responses under the constrained atmosphere component, but much stronger and more heterogeneous responses when atmospheric feedbacks are allowed.

Short summary
Geological records of past Saharan climate are often incomplete and difficult to date, while long climate simulations require extensive computing. We therefore developed an efficient empirical model from 30 climate simulations and records of Earth's orbit, carbon dioxide and sea level. It provides a practical way to study long-term Saharan climate change and can guide future simulations, field sampling and the dating of geological and archaeological records.

Antarctic Bottom Water influences global ocean circulation, heat storage, and carbon uptake. We compared an observational atlas, an ocean reconstruction, and 16 climate models by separating this water into three regional types. The reconstruction matched the observed large-scale patterns well, but many climate models showed substantial regional temperature and salinity errors. Correcting average biases improved some models, although errors in spatial structure remained.

This dataset quantifies the critical but overlooked role of sea spray in Southern Ocean air-sea heat exchange. We present a new gridded dataset of spray-mediated latent and sensible heat fluxes incorporating a full spray microphysical model, where spray generation depends on wind and wave states. Results show spray can double turbulent heat fluxes during extreme cyclones compared to bulk algorithms. This data is vital for understanding the Southern Ocean's impact on the global energy budget.

Cave stalagmites record the oxygen isotope of past rainfall and are used to reconstruct how monsoons changed, but due to the complexity of isotope impacting factors, what these records tell us is debated. We performed a 8300-year simulation with an isotope-enabled climate model, and show that rainfall amount is the key stable driver across global monsoons, while temperature and moisture pathways vary with region and time. Single-site records are noisy, but regional averages recover the signal.

We developed a high-resolution computer model to simulate how the ocean, sea ice, and ice shelves interact around Antarctica. This helps us understand their critical role in global climate and sea-level rise. Our model successfully captures essential features like major currents and seasonal ice changes. Despite some remaining biases, it provides a useful tool for predicting future changes in this vital and rapidly evolving region.

Antarctic sea ice has shifted from expansion to rapid decline since 2016. Using model outputs and data mining, we identified six sea ice regimes, shaped by different dynamic and thermodynamic conditions. A coastal regime, featured by sea ice transport and new ice formation, has shown area loss since 1979, accelerating after 2016. This coastal regime and a pack ice regime together control overall sea ice variability. Our work offers a new framework for understanding Antarctic sea ice changes.

Our study uses Google Earth Engine to create a dataset of Antarctic icebergs in the Southern Ocean (south of 55° S) from October 2018 to 2023. The dataset includes icebergs larger than 0.04 km², with details on their locations, sizes, and shapes. It shows significant changes in iceberg number and area, mainly driven by major ice shelf calving events – especially in the Weddell Sea. This resource fills key gaps in understanding iceberg impacts on the ocean and climate.

Antarctic sea ice has changed rapidly in recent years. Here we developed a deep learning model trained by multiple climate variables for extended seasonal Antarctic sea ice prediction. Our model shows high predictive skills up to 6 months in advance, particularly in predicting extreme events. It also shows skillful predictions at the sea ice edge and year-to-year sea ice changes. Variable importance analyses suggest what variables are more important for prediction at different lead times.

We incorporate ice damage processes into an ice-sheet model and apply the new model to Thwaites Glacier. The upgraded model more accurately captures the observed ice mass loss of Thwaites Glacier over 1990–2020. Our simulations show that ice damage has a notable impact on the ice mass loss, grounding-line retreat, ice velocity, and ice thickness of the Thwaites Glacier basin. This study highlights the necessity for incorporating ice damage into ice-sheet models.

For 1 century, the hemispheric summer insolation is proposed as a key pacemaker of astronomical climate change. However, an increasing number of geologic records reveal that the low-latitude hydrological cycle shows asynchronous precessional evolutions that are very often out of phase with the summer insolation. Here, we propose that the astronomically driven low-latitude hydrological cycle is not paced by summer insolation but by shifting perihelion.

Sea ice models are mainly based on non-moving structured grids, which is different from buoy measurements that follow the ice drift. To facilitate Lagrangian analysis, we introduce online tracking of sea ice in Community Ice CodE (CICE). We validate the sea ice tracking with buoys and evaluate the sea ice deformation in high-resolution simulations, which show multi-fractal characteristics. The source code is openly available and can be used in various scientific and operational applications.

We present a new atmosphere–ocean–wave–sea ice coupled model to study the influences of ocean waves on Arctic sea ice simulation. Our results show (1) smaller ice-floe size with wave breaking increases ice melt, (2) the responses in the atmosphere and ocean to smaller floe size partially reduce the effect of the enhanced ice melt, (3) the limited oceanic energy is a strong constraint for ice melt enhancement, and (4) ocean waves can indirectly affect sea ice through the atmosphere and the ocean.

The Last Glacial Maximum (LGM) marks the most recent extremely cold and dry time period of our planet. Using AWI-ESM, we quantify the relative importance of Earth's orbit, greenhouse gases (GHG) and ice sheets (IS) in determining the LGM climate. Our results suggest that both GHG and IS play important roles in shaping the LGM temperature. Continental ice sheets exert a major control on precipitation, atmospheric dynamics, and the intensity of El Niño–Southern Oscillation.

Due to a lack of observations, the structure of the Arctic atmospheric boundary layer (ABL) remains to be further explored. By analyzing a year-round radiosonde dataset collected over the Arctic sea-ice surface, we found the annual cycle of the ABL height (ABLH) is primarily controlled by the evolution of ABL thermal structure, and the surface conditions also show a high correlation with ABLH variation. In addition, the Arctic ABLH is found to be decreased in summer compared with 20 years ago.

The differences between Envisat and ICESat sea ice thickness (SIT) reveal significant temporal and spatial variations. Our findings suggest that both overestimation of Envisat sea ice freeboard, potentially caused by radar backscatter originating from inside the snow layer, and the AMSR-E snow depth biases and sea ice density uncertainties can possibly account for the differences between Envisat and ICESat SIT.

Short summary
The Global Ice-Ocean Modeling and Assimilation System (GIOMAS) can basically reproduce the observed variability in Antarctic sea-ice volume and its changes in the trend before and after 2013, and it underestimates Antarctic sea-ice thickness (SIT) especially in deformed ice zones. Assimilating additional sea-ice observations with advanced assimilation methods may result in a more accurate estimation of Antarctic SIT.

Short summary
Snow on Arctic sea ice acts like a blanket that traps heat and reflects sunlight, so it matters for the climate. Drawing on measurements from a year-long Arctic expedition, we improved models that simulate snow on the ice. Without wind-driven snow movement, the models overestimated snow depth. Adding a wind-driven scheme cut the average error by more than half. After tuning, simulated snow matched observations. The findings help project how Arctic sea ice may evolve in a warming climate.
