Increased Frequency, Duration, and Area of Winter Polynyas North of Greenland in a Warming Climate

Qi Shu, Qiang Wang, Haibo Bi, Dmitry V. Sein et autres

Abstract Polynyas play a crucial role in the polar marine ecosystems and climate system. Four winter polynya events north of Greenland have been observed, but the response of winter polynyas to climate warming remains unknown. This study investigates projected changes in winter …

Spatiotemporal Characteristics of Vertical Advective Heat Flux in the Arctic Ocean

Hualing Wang, Hailong Liu, Christian S. Haas, Lijing Cheng et autres

Abstract Vertical advective heat transport helps regulate upper-ocean heat exchange and ocean–ice interaction in the Arctic, yet the respective roles of mean circulation and mesoscale eddies remain poorly quantified. Using a 42-yr, high-resolution, eddy-permitting ocean–sea ice reanalysis [Regional Arctic Ocean/Sea Ice Reanalysis …

Poleward Shift of Arctic Oceanic CO 2 Uptake From Asymmetric Seasonal Changes Under Climate Warming

Rongrong Pan, Qi Shu, Qiang Wang, Liang Xue et autres

Abstract The Arctic region plays a disproportionate role in the global carbon cycle by acting as a critical sink for atmospheric CO 2 . However, how Arctic air‐sea CO 2 fluxes will respond to continued warming regarding their spatial and temporal changes …

Wind stress variability at the meso–gamma scale: Comparative observations from two adjacent offshore towers

Sheng Chen, Zhenya Song, Yongqing Yu, Fangli Qiao

The spatial variability of wind stress was investigated through eddy covariance measurements conducted at two offshore towers separated by 8.6 km. Observations showed that while wind speed spatial variability remains minimal (< 3%) for both the NW (parallel to the inter-site transect) …

Comment on egusphere-2025-2636

Xiaole Li, Zhenya Song, Xiongbo Zheng, Zhanpeng Zhuang et autres

Abstract. To address limitations in traditional discretization methods for ocean numerical modeling, this study develops a integral method with variable limit (IMVL) to enhance the simulation accuracy of thermohaline dynamics in ocean models. Under the Arakawa-C grid framework, we propose novel discretization …

A dipole pattern bias in marine heatwave intensity in the Kuroshio Extension simulated by the CMIP6 models: a role of northward shift of the Kuroshio Current

Wonkeun Choi, Heeseok Jung, Minkyoung Bang, Zhenya Song et autres

Abstract Climate models are essential for investigating and predicting marine heatwaves (MHWs), but their inherent biases pose challenges for accurately analyzing and projecting MHWs. As global warming intensifies, MHWs are expected to become more extreme, emphasizing the need for precise model evaluations …

Longitudinal serum total bile acid trajectories and risk of metabolic dysfunction-associated fatty liver disease: a retrospective cohort study

Huihui Chen, Xinyan Yu, Xueni Wang, Jiaojiao Huang et autres

BACKGROUND: Evidence from cohort studies on the relationship between metabolic dysfunction-associated fatty liver disease (MAFLD) and longitudinal changes in total bile acid (TBA) remains limited. This study aimed to investigate the association of TBA trajectories with new-onset MAFLD and liver fibrosis. METHODS: …

Arctic Ocean Dynamical Downscaling Data for Understanding Past and Future Climate Change

Qi Shu, Qiang Wang, Yan He, Zhenya Song et autres

Abstract The Arctic is one of Earth’s regions highly susceptible to climate change. However, in situ long-term observations used for climate research are relatively sparse in the Arctic Ocean, and current climate models exhibit notable biases in Arctic Ocean simulations. Here, we …
