Why Jet Streams Get Stuck and Weather Goes Nuts: 1 of 2 // Dec 18, 2018
From top-down, big-picture thinking on the climate system, it is clear that when Arctic temperatures increase much faster than lower latitude temperatures, the jet streams must slow down and become wavier; in fact I have discussed this since 2010.
Peer-reviewed science is finally catching up. In this and the next video, I chat on:
- Jet streams (planetary waves; Rossby waves) getting stuck in place, with:
- Large ridges and troughs,
- Causing extreme weather events via Quasi-Resonant Amplification.
