Hydrometeor Parameters Determined from the Radar Data of the SAMS Rain Erosion Program. AFCRL/SAMS Report No. 2

Abstract

The traditional equations relating the radar reflectivity factor and the precipitation rate are reviewed. The hydrometeor and radar parameters involved in the AFCRL/SAMS program at Wallops Island, Virginia, are defined and the methods of measurement and correlation are explained. The hydrometeor regions and transition zones of the Wallops Island storms are discussed and the methods of computing the precipitation rate, the liquid-water-content, and the integral of the liquid-water-content along the trajectories of the SAMS missiles fired into the storms are demonstrated. A case example is presented to illustrate the details of the computational procedures. The uncertainties of the liquid-water-content values determined from radar measurements are assessed, to a first approximation. Size distribution information is also presented for the different types of hydrometeors, based on theoretical distribution functions.
