An air mass climatology of Canada during the early nineteenth century : an analysis of the weather records of certain Hudson's Bay Company forts
The post journals of certain Hudson's Bay Company forts were examined for evidence that air mass frequencies during the first half of the nineteenth century were markedly different from those of a modern (1955-1959) period. The "partial collective" technique of Bryson was used to dete...
