Representative Values of Icing-Related Variables Aloft in Freezing Rain and Freezing Drizzle.
Radiosonde and surface observations in freezing rain (ZR) and freezing drizzle (ZL), and a limited number of aircraft measurements in ZR, have been examined for information on the magnitude and altitude dependence of meteorological variables associated with aircraft icing in these conditions. The va...
