Mysterious Engine of the Madden‐Julian Oscillation
Understanding the fundamental physics of the Madden‐Julian Oscillation, a phenomenon that occurs over the Indian and Pacific Oceans, remains a challenge in tropical atmospheric research.
Will COVID’s Cleaner Skies Muddy Climate Models?
Reduced greenhouse gas emissions for a year or two won’t slow down climate change, but they may throw off scientists’ ability to model short-term phenomena.
The Perils of Computing Too Much and Thinking Too Little
Big steps forward are synonymous with new ideas – a thought that merits mindfulness if we aspire to train students to do more than merely train machines.
Clearing the Haze Around Aerosol Assessments
An international gathering of scientists discussed the state of the art in assessments of how aerosol particles in the atmosphere affect Earth’s climate.
“Now Is the Time” for Green Recovery, Scientists Say
Otherwise, fossil fuel emissions will return to normal.
New Energetic Neutral Atom Emissions from Jupiter, Io, and Europa
The first Jovian off-equator Energetic Neutral Atom viewings reveal distinct emissions from Jupiter and the orbits of Io and Europa: Energetic particle injections surprisingly occur inside Io’s orbit.
Catching Elves in Argentina
The world’s largest cosmic ray detector accidentally spotted elves, an unusual lightning phenomenon high in the atmosphere. Now it’s intentionally looking for more.
Improving Atmospheric Forecasts with Machine Learning
An efficient, low-resolution machine learning model can usefully predict the global atmospheric state as much as 3 days out.
All Hands on Deck for Ionospheric Modeling
Challenges to studying the ionosphere’s ability to conduct electrical currents undercut scientists’ efforts to improve space weather forecasting models. Let’s tackle them together.
