New paper published in @agu.org's GRL by Klingebiel and colleagues #AC3 Arctic cold air outbreaks generate distinct cloud patterns, from organised streets to open cells. Our study reveals that both wind-driven and buoyancy-driven instability jointly determine these regimes. doi.org/10.1029/2026...

Really nice read, and great comparison to MOSAiC! Still very different scale, but this is a figure from our km-scale paper (doi.org/10.5194/gmd-...) last year, if you haven't seen it: gmd.copernicus.org/articles/18/... Anyway, great work, best wishes from Bonn!
