During December the Icelandic Low near 61°N, 34°W was 4 mb below 

 normal and about 125 miles offits mean monthly location. The 1014-mb 

 Greenland High was 2 mb weaker than normal. A negative 5-mb anomaly 

 was located about 500 miles east of Cape Race near 48°N, 40°W. A 

 positive 6-mb anomaly over eastern Quebec brought pressure departures 

 of more than 4 mb to the western Labrador Sea. 



January found the Icelandic Low near Gl'N, 40°^^ and 16 mb below 

 normal. It was only about 100 miles west of its average monthly 

 location. In February the 994-mb Icelandic Low near 59°N, 30°W was 

 8 mb below normal and 300 miles east of its mean position. This 

 large negative anomaly was the only significant low over the North 

 Atlantic. A slightly stronger than normal Greenland High resulted in 

 positive 5-mb anomalies south of 75°N, 33°W. 



During March the 998-mb Icelandic Low near 63 °N, 35 °W was 6 mb 

 below normal and about 350 miles northeast of its mean location. A 

 weak 1014-mb low was near Cape Sable, Nova Scotia. Two 8-mb positive 

 anomalies lay east of Newfoundland centered near 49''N, 44°W and 46°N, 

 30°W. The 1016-mb Greenland High was 4 mb below normal. 



April shows the Icelandic Low (1005 mb) as a trough extending from 

 the Labrador to the Norwegian Seas. The Greenland High (1026 mb) near 

 76°N, 38"'W was 4 mb above normal. In May the Icelandic Low near 60''N, 

 26°W further intensified to 5 mb below normal and was located about 

 300 miles northeast of its average position. West of the Icelandic Low, 

 pressures near Kap Farvel were 7 mb below normal. 



During June a positive 8-mb anomaly lay over the central North 

 Atlantic near 45''N, 37°W and a negative 10-mb anomaly was south of 

 Iceland near 62°N, 18°W. The Icelandic Low itself (1002 mb) was more 

 than 8 mb below normal. The 1015 mb Greenland High near 76''N, 38''W 

 was close to normal. July found the Greenland High (1014 mb) near 

 normal in central pressure but 400 miles northwest of its average 

 position for the month at 77''N, 44°W. The Icelandic Low split into 

 two parts, the stronger (1008 mb) off the west coast of Iceland, the 

 weaker (1010 mb) near Cape Smith (Hudson Bay). During August, average 

 pressures were from 1 to 3 mb above normal over almost the entire 

 North Atlantic.
