The North Atlantic Warm Hole and The Western Europe Floods

The North Atlantic Warm Hole (NAWH) is an area of persistent cooler-than-normal sea surface temperature anomalies (SSTA) becoming more prominent in 2013 related to increased melting of the Greenland Ice Sheet and persistent each warm season since that time including 2021. The NAWH has been displaced eastward to just-off Western Europe (Fig. 1). Aloft, the air cools over the NAWH and becomes a home for a persistent upper trough. During July, the upper trough has shifted slightly east from the 2021 source region causing excessive rain storms extending from France to Germany to Poland (Fig. 2). Most recently, the rains have caused devastating widespread flooding in Germany.
