“Mushballs” May Drive Ammonia Transport on Jupiter
Hail might account for observed depletions of ammonia in the planet’s atmosphere.
A GOLDen Way to Study Space Weather
A NASA mission is observing airglow in the upper atmosphere and uncovering what it tells us about Earth’s space weather system.
Megaripple Migration Offers Insights into Martian Atmosphere
The movement of large sand ripples, documented for the first time, suggests Mars is windier than we thought.
Ancient Sea Levels in South Africa May Offer Modern Analogues
Largely spared from disruptive tectonic activity, the South African coastline offers a natural setting to study sea levels from when Earth’s atmospheric carbon dioxide last reached today’s levels.
Meiyu: The Dragon Dictating Rainfall Variability in East Asia
According to Chinese myth, rain is water poured out of a dragon; in reality is the Meiyu that dictates rainfall in eastern Asia, producing rain belts jumping from south in spring to north in summer.
A Global View of Shapes and Sizes of Ice Crystals in Cloud Tops
Ice particles have systematic covariations and temperature dependences that are surprisingly consistent with a simple ice growth theory as revealed by satellites.
Power Outage When the Aurora Throws a Curve Ball
Omega-band aurora carries fast propagating electric currents in the azimuthal direction, producing geomagnetically induced currents that can cause power outage on the ground beneath.
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.
