In terms of the GLAAM this winter, it has been rather ho-hum. A steady 10-20N -AAM and 30-40N +AAM anomaly with occasional equatorial/subpolar emerging plus/neg respectively. If it wasn't for the SSW, the polar state in the troposphere would likely be strong with this background. pic.twitter.com/P7xCVslgn6
