During the first three months of 2020, much of northern Eurasia experienced record high temperatures. The authors conclude that it was primarily the stationary eddies associated with the Pacific North American (PNA) pattern and NAO that drove the anomalous descending motion that produced the observed deep layer of warming in the NH extratropics
