Comparing the current pattern to regimes in @Domeisen_D et al 2020 (https://t.co/05dvNt3Jmr), I see a blend of Atlantic ridge, Greenland block, and Scandi block. Not so much Euro block, which favors a strong tropospheric response to the #SSW. Next few weeks will be interesting. pic.twitter.com/90uYeHLju0
