Contrasting the synoptic drivers of the UK heatwaves of 1976, 2003, 2018 and 2022

open access: yesWeather, Volume 81, Issue 7, Page 212-221, July 2026.
UK summer heatwaves are dictated by the polar jet stream position and sea surface temperature (SST) variability, affecting the Summer North Atlantic Oscillation (SNAO) index. The SNAO can determine and influence the Central England Precipitation (CEP) and Central England Temperature (CET).

Model Biases and Sensitivities in Simulating Extreme Sea Ice Loss Around Svalbard During the January 2022 Record Cyclone

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract The record‐breaking Arctic cyclone of January 2022 caused an unprecedented sea ice loss in the Barents Sea near Svalbard, which was severely underestimated by both the ECMWF operational forecast and the CESM1 global climate model. To investigate this discrepancy and further explore the mechanisms that led to sea ice loss, we utilize a regional

Chemical Speciation Defines Archaeal Ammonia‐Oxidizer Distribution in Yellowstone Hot Springs

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract The hot springs of Yellowstone National Park (YNP) provide a natural laboratory for investigating the influence of chemical speciation and energy availability on the distribution of microbes. Among 133 inorganic chemotrophic energy supplies, total dissolved ammonia oxidation was consistently one of the highest across 63 YNP hot spring samples.

Effects of Wintertime Snow Depth Assimilation on Summertime Sea Ice Prediction Experiments Utilizing a Fully Coupled Regional Arctic Model With Perfect Boundary Conditions

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 7, July 2026.
Abstract During the past decades, the rapid decline of sea ice in the Arctic Ocean has substantially favored commercial navigation activities in the summertime. Numerical sea ice prediction on a seasonal scale plays a crucial role in guiding the programme of such activities, yet the role of snow depth data assimilation in numerical sea ice prediction ...

Omitting Frozen‐Soil Effects in Hydrological Models Introduces Biases in Estimated Runoff Sensitivity to Climate Change in Cold Basins

open access: yesWater Resources Research, Volume 62, Issue 7, July 2026.
Abstract Proper representation of cryospheric processes is essential for accurate hydrological simulation in cold mountainous catchments. Frozen soil, a key cryospheric element, is sometimes overlooked in hydrological models, and its hydrological influence remains insufficiently explored.
