Ice-Cover Growth Rates at Nearshore Locations in the Great Lakes

摘要

Ice thickness data from 32 nearshore locations around the Great Lakes were correlated to accumulated degree-days of frost over a 6- to 11-year period. A simple parastatistical model was used to compute ice-cover growth coefficients that reflect the relative impact of site-specific factors and processes on ice growth for each ice measurement site. In addition, two data sets were used to illustrate the inhibiting influence of snow on ice growth. Statistical parameters generated for each site and data set were used to summarize the degree of predictive accuracy. For these two seasons, the average standard error of estimate was 5.39 cm.
