Climate models have disagreed on the future evolution of the stratospheric polar vortex and links to the troposphere, but a new study revisits this problem with state-of-the-art climate models.
Simulating Surface Impacts of Stratospheric Sudden Warmings
New evaluations of climate model simulations show how the stratosphere polar vortex couples to surface weather.
Mars’s Dust Cycle Controls Its Polar Vortex and Snowfall
On Earth, the water cycle is a dominant climate force. On Mars, it’s the dust.
Polar Vortex Linked to Atmospheric Circulation at Daily Scale
A simplified representation of polar vortex at monthly scale was revised using a new method, and its daily association with air-sea teleconnections was analyzed to study weather impacts.
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.
An Extraordinary Winter in the Polar North
An exceptionally strong stratospheric polar vortex coincided with a record-breaking Arctic Oscillation pattern and ozone destruction during the 2019–2020 winter season.
Polar Stratosphere Resolves North Atlantic Jet “Tug of War”
Getting the polar stratosphere right is critical in the simulation of North Atlantic climate change, which is shaped by the interaction of Arctic Amplification and tropical upper tropospheric warming.
Polar Vortex Deformations Change Tidal Weather in the Mesosphere
Wind observations made by a high-latitude radar network shed new light on the rapid response of atmospheric tides in the upper mesosphere to stratospheric sudden warmings.
Atmospheric Gravity Wave Science in the Polar Regions
A joint special issue explores the potential of collaboration to help understand atmospheric gravity waves in the Polar Regions and their effect on global circulation.
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.
