Extremes of Hydrometeors at Altitude for MIL-STD-210B. Supplement: Drop-Size Distributions

Abstract

In the basic report for this supplement, estimates were provided for extreme rainfall intensities and associated liquid water content at altitude with 0.1 and 0.5 percent probabilities in the most severe month in the rainy tropics. Analagous values were also included for two all-time record rain storms: one for 1 min, and the other lasting 42 min. In this brief supplement, drop-size distributions are developed for the 1-min record, and the 0.1 and 0.5 percent 'Worst Month Tropics' from a theoretical expression that best fits the available empirical size distributions. Liquid water content obtained from an integral of this theoretical expression is compared to the liquid water content obtained by arithmetically adding the volumes of each drop for three drop-size distributions.
