The Mid-20th Century Winter Cooling in the Eastern U.S. Explained
A new analysis of historical jet stream behavior reveals that increases in jet stream waviness accounted for 55-71% of winter cooling in the eastern United…
Deep Root Respiration Helps Break Down Rocks
The carbon dioxide that results from respiration in and around deep roots is an essential component in the chemical weathering of sandstone rock soils.
ARMing SCREAM with Observations to Expose Cloud Errors
Modern ARM observations expose persistent process-level errors in a global cloud-permitting model, guiding future developments and improvements.
Obtaining Local Streamflow at Any Resolution
A new upscaling method ensures that global simulations at low resolution preserve the streamflow at local points of interest, such as stream gauges.
Shedding Light on the Mysteries of Deep Earthquakes
By analyzing forty deep earthquakes around the world, researchers discover the key role of a dual mechanism that allows earthquakes to grow larger and release…
Coupled Isotopes Reveal Sedimentary Sources of Rare Metal Granites
Using coupled isotopes, a new study shows that a class of economically important granites are derived by sediment melting without mantle input.
Coverage Factors Affect Urban CO2 Monitoring from Space
Orbital mechanics and environmental factors limiting the ability of Orbiting Carbon Observatory missions to collect data in space and time affect city-level monitoring, reporting, and verification goals.
Kuroshio Intrusions into Luzon Strait Increase Chlorophyll
Using in-situ observational data, scientists reveal that Kuroshio intrusions through the Luzon Strait increase small phytoplankton in the South China Sea.
High Relief, Low Relief — Glaciers Do It All
Contrary to conventional wisdom that glaciers just carve landscapes, they can also form low-relief surfaces by sheltering rock from erosion, enriching understanding of how mountain landscapes evolve.
Seasonal Iron Cycle and Production in the Subantarctic Southern Ocean
Long-term monitoring at a site in the subantarctic region south of Australia combined with ship-based observations reveals three distinct phases between cycles of phytoplankton productivity and dissolved iron.
Creep Cavitation May Lead to Earthquake Nucleation
Ultramylonites, rocks of ultrafine grainsize, bring records of nanometer-scale cavities generated at the base of seismogenic crust along Japan’s largest on‐land fault.
Rock Solid Augmentation: AI-Driven Digital Rock Analysis
Boosting digital rock images with AI-powered augmentation and quality analysis could improve subsurface engineering decisions.
Inferring River Discharge from Google Earth Images
Critical flow theory can predict river discharge based on the spacing of standing waves captured by Google Earth images.
Bringing Storms into Focus
A new study evaluates the performance of kilometer-scale models in predicting large tropical storms, which are key drivers of extreme rainfall and severe weather.
Revised Emissions Show Higher Cooling in 10th Century Eruption
The associated cooling from the Eldgjá eruption is larger than previously predicted and better matches tree-ring temperature reconstructions based on updated estimated emissions.
