The Who, What, When, Where, and Why of the Polar Vortex
Here’s a rundown of what this atmospheric phenomenon really is and why it matters.
Severe Hailstorms Are Costly and Hard to Predict
Hail causes huge financial losses worldwide every year. But we still can’t predict when hail will strike. Climate scientists from around the world are teaming up to figure out how to change that.
Convective Transport Explains “Missing” Ice near the Tropical Tropopause
Spaceborne lidar shows that more ice than expected is leaving the tropical tropopause layer in the atmosphere.
New Global Mesoscale Convective System Tracking Database
A 20-year high-resolution global mesoscale convective system tracking database reveals the characteristics of mesoscale convective systems and their significant contributions to global rainfall.
Dune Aurora Explained by Satellite-Ground Studies
Spacecraft observations support the mechanism for explaining auroral dunes observed from the ground by citizen scientists.
Noctilucent Clouds Light Up Northern Germany
A shift in the tropopause jet may have triggered the unusual number of high-altitude clouds that briefly appeared in the early summer of 2019.
Global Effects of Disruptions to the Stratospheric Circulation
Major disruptions to the stratospheric circulation have far-reaching effects, including increased likelihood of snowstorms, growth of the ozone hole, and interference in global telecommunications.
Upwind Forest Buffers Rondonia Cropland Against Regional Drought
During severe Amazonia droughts when oceanic supply of moisture failed, the magnitude of rainfall reduction over Rondonia was moderated by enhanced moisture supply from upwind forests.
Paying Attention to the “Ignorosphere”
Scientists discuss geospace and what we could learn if we put some more eyes on this region in the atmosphere. Read more in our special themed issue.
