The most striking feature of the 700-mb. circulation during March 1951 (fig. 1) was the extensive area of positive height anomaly extending from middle latitudes in the Atlantic Ocean and eastern North America northwestward into the Canadian and Siberian Arctic and thence southward through the Bering Sea into the Pacific Ocean, The centers of "560 feet near the North Pole and $450 feet in the Davis Strait were the largest height anomalies in the entire Northern Hemisphere. At lower latitudes in the Atlantic there was a deep trough almost directly south of the abnormally strong ridge in Green-land and the northern Atlantic. This pattern of a ridge latitudinally superimposed over a trough, or positive height anomaly north of negative height anomaly, is characteristic of pronounced blocking action, where warm
