Abstract

The most likely number of days with snow on the ground during an individual month is expressed empirically as a function of the mean temperature and total precipitation for that month, as well as the presence or absence of a snow cover at the end of the preceding month. Although this study is of some value in the field of synoptic climatology, it was designed primarily to serve as a useful method for generating snow cover within numerical weather-prediction models which do not contain water- or snow-budget formulas.
