Loss of the aging ACE-FTS and MLS satellite instruments will create a “data desert” around stratospheric composition, suggests a paper by @rosssalawitch.bsky.social et al in #BulletinAMS. Observation gaps may hinder understanding of climate change.

An early but interesting end to the 2024-25 polar vortex season After spending much of the season with super strong wind speeds, the polar vortex bowed out two weeks ago, with the core west-to-east winds sliding off the pole. However, as it winds down for the seas...

The 2024-2025 polar vortex season is wrapping up with an interesting "final stratospheric warming" event. Read more on the NOAA climate.gov blog today!

I've made a starter pack of people who work on the stratosphere/middle atmosphere and/or often post about the stratosphere, including forecasts of the polar vortex.

Please do suggest anyone I've missed – quite hard to keep up with everyone on here now!
