Abstract : The paper examines first the available information on freezing rain and freezing drizzle in an attempt to define the applicable parameters, viz. temperature, precipitation rate (or liquid water content), drop size, and wind speed, in order to permit representation simulation and testing. Methods of measuring the simulated rain intensity and drop size are presented, and the problem of incomplete drop supercooling is addressed. Methods of simulating freezing rain in the cold chambers and wind tunnels of the National Research Council of Canada are described, and the results of tests are used to illustrate various facets of the problem.
