The first study to examine the ability of a suite of general circulation models to predict sudden warmings in Earth’s stratosphere highlights the potential for improving Northern Hemisphere forecasts.
El Niño events have significant global impacts on weather and climate, but these reach up into the stratosphere, beyond the troposphere where most of Earth’s weather takes place.
The answer involves the intricacies of stratospheric circulation, which, if better represented in climate models, could help predict extreme weather events in Siberia and elsewhere.
Airborne telescopes gave scientists a sky-high view of the 2017 Great American Eclipse as they took measurements that are difficult to obtain from the ground.

High above Earth’s surface, air temperatures occasionally increase suddenly, producing widespread effects on weather, air chemistry, and telecommunications.
By comparing Cassini observations spanning ten years, Saturn’s equatorial oscillation is shown to have similarities to Earth’s Quasi-Biennial Oscillation and Semi-Annual Oscillation.
For the first time, scientists have observed a deviation from the typical alternating pattern of easterly and westerly winds in the equatorial stratosphere.
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.
The ozone hole over Antarctica has shrunk by 16% since its peak in 2000, and some suspect it may disappear entirely by midcentury.
