Germany has a warning for tonight, a storm coming from the South West. I thought, SouthWest is unusual for winter, hence I checked the broader conditions @ #EarthNullschool https://earth.nullschool.net/#current/ocean/primary/waves/overlay=significant_wave_height/orthographic=-30.24,41.58,281/loc=-27.995,53.889

So there's this #PolarVortex #SSW split still ongoing, as seen in windspeeds at 10hPa.
Top right: the normal #jetstream at 250hPa races from North America straight to Europe because, I reckon, there's the hard border between the Azores High pressure system and the Iceland Low. (not in picture). Where the jet "hits" Spain, it gets driven North East. Dunno why. (And creates that storm in Germany. #weather )
Bottom left: sea surface temperature anomaly in the #Atlantic with a location in the #ColdBlob highlighted. It's currently 0.1°C colder than its longterm average. Yay. And for real it's 2.1°C warm there. #AMOC
And now the eyeopener🥁
the bottom right pic shows "significant wave height". The cold blob sees 9-10m waves = ocean mixing, bigly.
Are waves 1 of the 🌡️ reasons that blob forms where it does?
