The patterns of salinity and temperature diverged greatly from 

 this model in the Last three months of 1976. Dickson and Namias 

 (Paper 2) noted that during 1976 the upper air (70C mb) patterns 

 also changed noticeably. During the first three seasons the

 established itself over the eastern North Pacific and west coast 

 of North America. The ensuing fair weather and 1976-77 winter
