Northeast Canada in Feb, perfect spot for the NASA NURTURE field campaign. We’re flying NASA’s GIII plane to observe features in the atmosphere (synoptic scale tropopause polar vortices) that act as precursor to extreme weather, like cold air outbreaks & high impact storms. 📷 from Research Flight 8
En route to join the NASA NURTURE mission, a large-scale field campaign happening now. We’re coordinating research flights through atmospheric phenomena that contribute in the development of high-impact extreme weather, including major winter storms and cold air outbreaks. espo.nasa.gov/nurture

It’s cold now, but the next punch of Arctic air will take it to another level.

It’s always great to chat about the stratosphere. The last major sudden stratospheric warming event to occur in November was in 1968! We might do it again this year. We’ve had a few minor events in since then (e.g., 1996, 2000, 2009, 2016) and they hint at an active wintery December!
Andrew Freedman@afreedma.bsky.social · 9mo agoAn unusually early sudden stratospheric warming event is likely to send the polar vortex on the move. Questions exist re: how this will affect US weather, but odds for colder, snowier weather are ticking up esp. in Central/Eastern US www.cnn.com/2025/11/19/w...
