| Summary: | January 1972 was characterized by an extremely vigorous circulation at midlatitudes around almost the entire Northern Hemisphere, with the exception of the European sector where strong blocking prevailed (figs. 1, 2). The subtropical high-pressure belt was stronger than normal and was displaced north of its usual posit,ion all the way from the western Pacific to the central Atlantic, while deeper than normal cyclonic centers of action prevailed at high latitudes over Baffin Island and across northern Siberia. The 700-mb wind maximum was quite close to its normal position from the central Pacific to the central Atlantic, but mean wind speeds were considerably greater than normal, particularly over North America and the western Atlantic where a peak value of 25 m/s (10 m/s above normal) was observed south of Nova Scotia (fig. 3). Under the influence of the strong European blocking ridge |
