RELATIONSHIPS BETWEEN CLIMATE AND REGIONAL VARIATIONS IN SNOW-COVER DENSITY IN NORTH AMERICA.
Abstract
Analysis of snow-cover observations made during November - March at 27 stations in Alaska, Canada and the northern United States for a 2 to 11 year period showed that the average snow density can be classified in four general categories. A nomograph in which the average winter air temperature and wind speed are the independent variables makes it possible to estimate the average snowcover density for any location in the Arctic, subarctic and North Temperate Zones. A comparison between observed and estimated densities for ten other test stations yielded a correlation coefficient of 0.91 with a standard error of estimate of 0.016 g/cu cm. An average snow density map of North America was drawn and the continent was divided into areas based on the four categories. (Author)
