Emissions of short-lived chlorine-based chemicals that deplete ozone are increasing worldwide. But over some regions of Asia, these chemicals may be on a fast track to the ozone layer.
Stratosphere/troposphere interactions
Does Water Vapor from Volcanic Eruptions Cause Climate Warming?
By studying past volcanic eruptions, scientists find that the amount of water vapor reaching the stratosphere during moderately explosive eruptions may not be contributing to the greenhouse effect.
Antarctica's Ozone Hole Is Healing, Scientists Say
The ozone hole over Antarctica has shrunk by 16% since its peak in 2000, and some suspect it may disappear entirely by midcentury.
When Thunderstorms Have Wings
A new study uncovers the origin of a gull wing–shaped cirrus cloud above an Argentinian thunderstorm captured in satellite images.
Connecting Thunderstorms and Climate Through Ozone
New data links thunderstorms to climate via their impacts on aerosols, ozone, and water vapor in the stratosphere.
The Forgotten Water Vapor at High Altitudes
Scientists find that estimations of high-altitude atmospheric water, critical for the greenhouse effect, are not as accurate as previously thought.
Methyl Chloride Can Track Tropical Air in the Lower Stratosphere
A new study shows that trace gas samples collected aboard commercial airliners can be used to determine the origin and dynamics of atmospheric air masses.
Atmospheric Waves Help Cool Our Planet
A new method makes a direct estimate of the impact of atmospheric waves on water vapor concentrations in the stratosphere.
Do All These Weather Satellites Really Improve Forecasts?
A team of researchers put an array of space- and ground-based weather instruments to the test and found that the common weather balloon is irreplaceable for forecasting rainfall.
