Miso‐vortices along an oceanic cold front – 27 November 2015

Figure 1 is a processed Meteosat Second Generation geostationary satellite visible image for 1315 UTC 27 November 2015. A band of cloud can be seen trailing from western Scotland south-south-westwards through the Irish Sea and west of the Bay of Biscay. According to the Met Office surface analysis for 12 UTC 27 November (not shown) this marked a double cold front trailing from the Norwegian Sea to the central North Atlantic. A minor wave along this front is marked by the ill-defined arc of cloud over Ireland and stretching to the Western Isles. Cold air flooding southwards is characterised by shallow open-cell convection in the eastern Atlantic.
