Distribution of Maximum Annual Water Equivalent of Snow

For later development of design snow loads, the water equivalent of snow on the ground appears to be the best The appropriate climatological series for this is the winter Among many distributions investigated, the lognormal Distributions fitted to 140 stations provided data In southern areas of the United States, where snow does This requires the A contour map is provided of the mixture parameter estimate. meteorological variable for determining design values. season maximum accumulated water equivalent series. distribution provided the best fit to these climatological series. for preparing contour maps of the parameter estimates. not occur every year, the climatological series is a mixture of zeros and water equivalent maxima. fitting of mixed distributions in these areas. Methods for determining confidence intervals for quantiles from both distributions are developed.
