On the Quantitative Determination of Precipitation by a Radar.
Abstract
Measurements of radar reflectivity, rainfall rate and drop-size distribution were made for three classes of rain type: drizzle, uniform steady rain, and thunderstorms. Power-law relationships of the type a(R to the b power) where Z is radar reflectivity factor, R is rain intensity, and a and b are constants, were found for the three classes of rain. For the measurement of daily rainfall amounts exceeding 10 mm, these relationships produced a standard error of estimate of plus or minus 13%. For the same data, use of a single Z-R relation of all types of rain gave a standard error of plus or minus 28%. (Author)
