Summary: | Blocking weakened considerably over and near North America during November and strengthened in the eastern portion of the Northern Hemisphere. Figure 1 shows changes in the mean 700-mb height anomaly from October to November 1968. Heights were generally lower in November from the Maritime Provinces to the Beaufort Sea. Heights decreased most near Davis Strait where a strong ridge in October weakened about 110 m as the Icelandic Low became established near southern Greenland (fig. 2). The ridge formerly over western Europe and the United Kingdom m.oved eastward and acquired a strong negative tilt from Greenland to southern Russia while height anomalies increased 160 m over northern Scandinavia. This was accompanied by marked high latitude |
