Estimates of Air and Moisture Flux into Hailstorms on the High Plains

Abstract
Based on airborne observations, estimates of air and moisture flux have been calculated for 18 hailstorms: eight in Colorado, one in Oklahoma, and nine in South Dakota. The average air flux for hailstorms in this study was 2.3 × 1011 gm sec−1, while the moisture flux averaged near 2.1 × 109 gm sec−1. Precipitation efficiency for eight thunderstorms was found to be near 55%, though two severe hailstorms did exhibit slightly less efficiency.
