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.
New evaluations of climate model simulations show how the stratosphere polar vortex couples to surface weather.
On Earth, the water cycle is a dominant climate force. On Mars, it’s the dust.
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.
Here’s a rundown of what this atmospheric phenomenon really is and why it matters.
An exceptionally strong stratospheric polar vortex coincided with a record-breaking Arctic Oscillation pattern and ozone destruction during the 2019–2020 winter season.
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.
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.
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.
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.
