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 aR 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
