Extremes of Hydrometeors at Altitude for MIL-STD-210B
Abstract
Extremes of precipitation aloft--which would be exceeded with only 0. 5 percent probability in the rainy tropics during the rainiest months--are mandatory for design of military equipment that must operate at altitude any place in the world. Also needed are greatest extremes at altitude which should be considered in design when equipment failure, during encounters of improbable intensities, would endanger human life. Frequency distributions of such rainfall intensities and the associated liquid water content in the precipitation and clouds are not available in the climatic inventory. By extrapolating upward, there are developed nearly instantaneous surface precipitation intensities with appropriate probabilities, utilizing available research data, four models, and tabulations of water content aloft. Complete findings are presented in a single table which includes intensities, liquid water content of precipitation, and liquid water content of cloud particles for nine levels up to 18 km for storms applicable to MIL-STD-210B design philosophy.
