Space Hurricanes Swirl in the Southern Hemisphere, Mostly in Summer
Previous studies of the recently discovered space weather feature focused on the Northern Hemisphere. Dozens hit the Southern Hemisphere each year, new research shows.
Equation Discovery for Subgrid-Scale Closures
Machine learning can discover closure equations for fluid simulations. A new study finds that common algorithms rediscover known, unstable closures, which can be stabilized with higher-order terms.
Ocean Impacts on European Winter Weather
State-of-the-art high-resolution models are needed to reveal the ocean’s role in driving extra-tropical weather systems.
The Size of the Great Salt Lake Affects Storm Precipitation
Utah’s most famous body of water is shrinking, and storms might deliver less precipitation than normal if that trend continues.
Machine Learning Masters Weather Prediction
Community datasets and evaluation standards are needed to further advance machine learning for weather prediction.
Rain Comes to the Arctic, With a Cascade of Troubling Changes
Rain used to be rare in the Arctic, but as the region warms, so-called rain-on-snow events are becoming more common. The rains accelerate ice loss, trigger flooding, landslides, and avalanches, and create problems for wildlife and the Indigenous people who depend on them.
Towards a Unified Framework for Earth, Mars, Titan, and Exoplanets
From a simple set of in situ or synthetic data, a general unified model has been developed to calculate turbulent fluxes and evaporation rates on any rocky body with an atmosphere.
Phased-Array Radar Detection of Electrically Aligned Ice Crystals
A new method for observing electrically aligned ice crystals in localized storms can detect the onset of electrification and lightning in developing storms.
Rare “Glory” Possibly Seen on Exoplanet’s Horizon
This rainbow-like atmospheric phenomenon depends on a very specific set of circumstances. It is common on Earth and incredibly rare beyond it.
