Abstract : Frozen precipitation is observed in various forms and its frequency varies by month and by region. Graphs showing the probable occurrence of frozen precipitation at eleven locations in the U.S. and Canada are presented as possible aids in devising methods for improving winter operations. Average temperatures observed at the time of precipitation occurrence are also given and related to long term mean air temperatures. These temperatures as well as some information on extremes in frozen precipitation may be helpful in determining the specifications required for developing heating systems for the control of ice and snow in large cities. For example, the information extracted from Figures 5 and 8 provides a potential user with knowledge of the maximum duration and probable concurrent air temperatures for freezing rain and/or freezing drizzle storms.
