The number of storm centers traversing the North Pacific was far 

 above normal . They moved eastwaror tracking progressively 

 farther north to the Latitude of Seattle/ and east of loOw 

 recurved cy clon i cal ly ^ with the majority moving toward and over 

 the Bering Strait. The Aleutian low was far to the east of its 

 usual position. A high pressure cell covered most of the eastern 

 Pacific south of 45 N - 



The 700 mb pattern of fast zonal flow produced the highest March 

 wind speeds since records began. Record breaking warmth 

 persisted into March over most of the United States. 



£&Cii ~ In the North Atlanticr the month was relatively storm 

 free/ with storm centers concentrated northwest of a line from 

 Newfoundland to Iceland. A ridge stretched northeastward from 

 the Azores high tc SON/ 15Wr where pressure was nearly 1C mb 

 higher than normal. 



In the North Pacific there were more/ but smaller and less 

 intense/ low pressure storm centers than normal/ and they tracked 

 more nearly east than the normal northeasterly direction. The 

 anomaly pattern was weak/ with a negative anomaly trough over the 

 Aleutian Islands associated with the primary concentration of 

 storm tracks. 



Fast/ zonal 730 mb flow persisted across the Pacific/ but a 

 trough developed off the U.S. west coast/ a ridge over the Great 

 Plains/ a trough off the U.S. east coast/ and a pronounced ridge 

 west of Europe. 



Ma^ - Low pressure storm centers formed farther off the U.S. east 

 coast and were fewer in number than normal/ but followed the 

 usual storm tracks across the North Atlantic. There was a -12 mb 

 anomaly centered in the Icelandic low/ with a large area of 

 mildly positive anomaly south of A5N. 



The number of storms in the North Pacific was near normal/ but 

 they were more widely dispersed than usual. The Pacific high and 

 Aleutian low remained stronger than normal. 



Mean 7C0 mb flow across the North Pacific was flat and stronger 

 than normal/ while waves developed over the continent with a 

 trough over tne U.S. west coast/ a ridge in the western United 

 States/ and an eastern trough west of the Appalachians. Mean 

 flow over the western North Atlantic flattened and strengthened 

 considerably/ while an anomalous Low developed above the surface 

 low/ and the ridge intensified over Scandinavia. 



June - North Atlantic storm paths originated in Ungava Bay/ moved 

 southeastward to 5uN/ 35W/ then recurved toward Iceland. None 

 crossed the British Isles or the European continent. A strong
