| Summary: | trough. This trough appeared in central North America and became a full latitude feature extending from the southern United States to the Low over the Arctic Basin. A strong blocking positive height anomaly formed farther to the east over Canada, while a slightly weaker positive center, that had been present during August, persisted east of Greenland (fig. 2). This block is much more evident in the anomaly pattern than in the actual 700-mb. flow, and instead of the usual southward displacement of the main band of westerlies with blocking, there was one axis of maximum wind speed near the normal position (fig. 3) over eastern North America with a second maximum to the north and a third branch to the south over the western Atlantic. The deep Low which had been over eastern Canada in |
