North American Monsoon Response to Antecedent Soil Moisture and Snow in the Colorado Plateau
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 16, 28 August 2025.Abstract This study explores the relationship between spring soil moisture and snowpack in the Colorado Plateau (CP) and the onset of the North American Monsoon (NAM) using reanalysis data. We find that increased spring soil moisture in the CP corresponds to later NAM onset dates throughout much of the southwestern United States (US) and northwestern ...

Surface and Subsurface Biogeochemical Impacts of the 2019 Northeast Pacific Marine Heatwave
Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.Abstract Following the highly impactful 2013–2016 Marine Heatwave (MHW), another MHW occurred in the Northeast Pacific during summer 2019. While the physical drivers of this event are well described, its biogeochemical impacts remain poorly understood. We use Ocetrac, a Python package that tracks spatiotemporal extreme events, to identify physical and ...

Threshold Domain Sizes for Multifractality in Sea Ice Deformation
Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.Abstract Sea ice dynamics has long been studied in both engineering and geophysical contexts, but unifying these scales remains elusive. Multifractality in ice deformation is a key metric for validating large‐scale continuum models. We perform a multifractal analysis on high‐resolution ship radar data over one winter.

IOP Conference Series: Earth and Environmental Science, 2010 Analysis of current and historical data demonstrates that the cryosphere component are very sensitive to the climate change thus proving its role as the climate indicator. In the process of this a pattern of the changes clearly reflect regional climate characteristics.

The Pacific Arctic Region Has Become a Sink for Multiyear Sea Ice Coverage
Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.Abstract The Pacific sector (PAC) is critical for both dynamic transport and thermodynamic melting of Arctic multiyear ice (MYI). Long‐term observations from 1980 to 2023 reveal an unprecedented decline (−3.87 × 104 km2 yr−1) in PAC MYI area (MYIA) during winter, surpassing the summer loss.

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.Abstract Antarctic sea ice, which undergoes large seasonal changes and plays a crucial role in the global climate system, showed a gradual increasing trend in its extent from the late 1970s to 2015 but experienced a sharp decline in 2016, followed by record lows in subsequent years.

Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.Abstract In this paper, we seek to understand how useful the Western United States Dynamically Downscaled Data set (WUS‐D3) is to water managers in California, as well as how climate change will impact the state's water resources. We analyze intrannual snowpack water storage skill of this data set over the southern Sierra Nevada, and project future ...

Minimal Arctic Sea Ice Loss in the Last 20 Years, Consistent With Internal Climate Variability
Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.Abstract Over the past two decades, Arctic sea ice loss has slowed considerably, with no statistically significant decline in September sea ice area since 2005. This pause is robust across observational data sets, metrics, and seasons. Large‐ensemble CMIP5 and CMIP6 simulations reveal that such periods with minimal sea ice decline under increasing ...

Seismic Tremors From Sea‐Landfast Ice Interactions Near Utqiaġvik, Alaska
Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.Abstract The mechanical state of Arctic landfast sea ice remains poorly constrained due to limited observations. This study investigates interactions between drifting sea ice and the coastal landfast ice near Utqiaġvik, Alaska by integrating data from broadband seismometer, Distributed Acoustic Sensing, and marine radar.

State‐Dependent North Atlantic Response to Volcanic Eruption Clusters
Geophysical Research Letters, Volume 52, Issue 15, 16 August 2025.Abstract Paleoclimate reconstructions suggest that clusters of volcanic eruptions may trigger sustained cooling events, but the underlying mechanisms and their potential dependence on the mean climate state remain poorly understood. Here, we investigate the climate response to an idealized eruption cluster using two coupled climate models under fully ...
