Using Multiple Models to Improve Seasonal Forecasting

by Terri Cook 15 April 201929 March 2022

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.

Global Impacts of ENSO Reach into the Stratosphere

by D. I. V. Domeisen, C. I. Garfinkel and A. H. Butler 19 February 201929 March 2022

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.

Why Are Siberian Temperatures Plummeting While the Arctic Warms?

by Kimberly M. S. Cartier 26 July 201829 March 2022

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.

Seeing Green: A Stratospheric View of the 2017 Total Eclipse

by Kimberly M. S. Cartier 24 May 201815 June 2022

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.

How Sudden Stratospheric Warming Affects the Whole Atmosphere

by N. M. Pedatella, J. L. Chau, H. Schmidt, L. P. Goncharenko, C. Stolle, K. Hocke, V. L. Harvey, B. Funke and T. A. Siddiqui 20 March 201829 March 2022

High above Earth’s surface, air temperatures occasionally increase suddenly, producing widespread effects on weather, air chemistry, and telecommunications.

Earth-like Oscillations Detected in Saturn’s Stratosphere

by S. Stanley 21 February 201829 March 2022

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.

The stratosphere, seen here as the blue region above the red-orange troposphere, sports a mysterious wind anomaly in its quasi-biennial oscillation, scientists say.

Mysterious Anomaly Interrupts Stratospheric Wind Pattern

by Sarah Stanley 2 September 201629 March 2022

For the first time, scientists have observed a deviation from the typical alternating pattern of easterly and westerly winds in the equatorial stratosphere.

Does Water Vapor from Volcanic Eruptions Cause Climate Warming?

by A. Branscombe 11 August 201629 March 2022

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

by JoAnna Wendel 30 June 201629 March 2022

The ozone hole over Antarctica has shrunk by 16% since its peak in 2000, and some suspect it may disappear entirely by midcentury.
