Median Volume Drop Diameter for in Cloud Icing Simulations
Cloud liquid water content and drop diameter have been measured during in-cloud icing conditions at the summit of Mt.Washington in New Hampshire for many years.The average median volume drop diameter from those measurements is about 14 μm.That size may be governed by the typical conditions on the mountain,with different distributions of drop diameters in icing clouds elsewhere.For example,in the Columbia Basin in eastern Washington,severe icing occurs with relatively light winds and high visibilities compared to Mt.Washington.This indicates that the drops in those clouds may be substantially larger than is typical for Mt.Washington.We use the dataset from Mt.Washington to relate drop number density and drop median volume diameter to the associated weather conditions.Drop number density results are inconclusive.Median volume drop diameter decreases with increasing wind speed and increases with warming temperatures.
