New research suggests that sea-salt aerosols seed large raindrops that starve clouds of water needed to make lightning. But not all scientists are convinced it’s simply about salt spray.
Modeling
A Better Operational Lava Flow Model
By segmenting the vertical structure of a lava flow, the Lava2d model provides more realism to operational lava forecasts.
Converging Toward Solutions to Grand Challenges
A hypothetical, space weather–induced power grid catastrophe served as a practice case for building unity and collaborative skills among disparate communities to address a major global hazard.
Deep Learning for Hydrologic Projections Under Climate Change
Extrapolation or not? Big data may help deep learning to go places where it has not been before by transferring learned hydrologic relationships.
Satellites Get First Full-Year View of Arctic Sea Ice Thickness
The AI-based monitoring method may unlock data that could improve shipping safety and climate predictions.
Modeling Groundwater Responses to Earth Tides
Tidal fluctuations in water well levels can reveal characteristics of the subsurface, and a new model based on coupled physics delineates the limitations of inherently simplistic analytical solutions.
Modeling Stratosphere-Troposphere Coupling in a Changing Climate
Climate models have disagreed on the future evolution of the stratospheric polar vortex and links to the troposphere, but a new study revisits this problem with state-of-the-art climate models.
Tracing Anthropogenically Emitted Carbon Dioxide into the Ocean
Researchers labeled anthropogenically emitted carbon and tracked it with an ocean circulation model to determine whether it winds up in the sky or sea.
Fantastic Ice-Nucleating Particles and How to Find Them
Recent advances in measurements and models are paving the way to transform fundamental understanding and simulation of ice-nucleating particles and their climate impacts.
Slight Shifts in Magnetic Field Preceded California Earthquakes
Magnetometers detected faint signals that with further study, may improve our understanding of what happens before earthquakes and offer promise for early detection.
