New Characterization of the Mesospheric Polar Vortices
Polar vortices play a central role in coupling the atmosphere from the ground to the middle atmosphere. New satellite diagnostics describe mesospheric polar vortices and coupling to lower altitudes.
UCAR to Keep Managing National Center for Atmospheric Research
The head of the University Corporation for Atmospheric Research says he is excited about “taking our science to the next level.”
Wind Speed Governs Turbulence in Atmospheric Inversions
Measurements made during a field campaign in Idaho indicate that the speed of winds 2 meters above Earth’s surface determines the type of turbulence present in nighttime inversions.
How Did Life Learn to Breathe?
Scientists unravel the conditions under which life evolved to breathe oxygen—and the findings have some stellar implications.
Dramatic Stratospheric Warmings Carved a Hole in the Ionosphere
A new study of sudden temperature spikes in Earth’s stratosphere could improve space weather forecasting.
Budgeting Ozone-Depleting Emissions from Coastal Tidal Marshes
Brackish wetlands and their salt-tolerant vegetation are significant methyl halide emitters. The natural emissions add chlorine and bromine to the stratosphere, which break down ozone.
New Modeling Framework Improves Radiative Feedback Estimates
A new approach offers insights into the relationship between surface temperature and top-of-atmosphere energy imbalances and improves the understanding of important climate feedbacks.
Great American Eclipse Data May Fine-Tune Weather Forecasts
Measurements taken by an automated national meteorological monitoring network during the 2017 total solar eclipse illuminate how the land and atmosphere respond to a sudden loss of sunlight.
High-Altitude “Wind Walls” Discovered near Magnetic Poles
Satellite imaging reveals two narrow channels of extreme winds surrounded by gentle opposing flow 140–250 kilometers above sea level.
