Unprecedented Open‐Ocean Polynya in Breid Bay, East Antarctica in Winter 2024

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract We document an unprecedented winter open‐ocean polynya in the Breid Bay, on 4 August 2024, attaining a maximum area of 89,121 km2. Prior to opening, sea‐ice concentration declined from ∼96% in early July to below 25% by 30 July 2024, indicating substantial preconditioning of the winter ice cover.

Achieve Medium‐Range SST Forecast by Rolling 1‐Day Deep Learning

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Deep learning has revolutionized short‐term Sea Surface Temperature (SST) forecasting, but often struggles with cumulative error propagation and operational complexity in medium‐range predictions. To achieve lightweight and temporally continuous SST forecast, this study introduces two novel training strategies, Rolling Training and Multistep ...

Dampened Diurnal Cycles of Hot‐Wet Extremes in Urban Areas Contrast With Thermally Driven Daytime Stress in Rural Landscapes of Beijing‐Tianjin‐Hebei Region

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Hot‐wet extremes (HWEs) are intensifying in the Beijing–Tianjin–Hebei region, but their fine‐scale diurnal urban–rural contrasts remain unclear. Using summer observations from 1,962 automatic weather stations during 2016–2024, we identify threshold‐exceeding HWE days and show that urban areas experience more compound day–night and independent ...

Subsurface‐Intensified Marine Heatwaves: A Hidden and Intense Warming Threat to Tropical Ocean Ecosystems

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Understanding how the vertical structure of marine heatwaves (MHWs) influences ecosystems remains limited. Here we investigated subsurface‐intensified (Type‐1) and surface (Type‐2) MHWs in tropical oceans using reanalysis data sets. Type‐1 MHWs occur most frequently and are concentrated near the equator, with a threefold greater median ...

Observational Evidence for Accelerated Warming and Salinification Propagating Into the Deep Mediterranean

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Acceleration, rather than a gradual linear response, is emerging as a defining feature of ocean change in the Anthropocene. Surface‐forced warming propagates into the deep ocean over decades to centuries, but semi‐enclosed basins such as the Mediterranean Sea may respond more rapidly.

Changing Antecedent Land‐Surface Conditions Can Amplify Future Heat Extremes Across New Zealand

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Extreme heat in New Zealand is projected to intensify faster than mean warming, but the mechanisms remain unclear. Using dynamically downscaled CMIP6 projections, we investigate whether land–surface moisture constraints contributes to future heat‐extreme intensification in a maritime climate. Across six downscaled models, evaporative fraction (
