Abstract : An analysis of raindrop size distribution curves recorded in various parts of the world is given. The rain studied is divided into three types with respect to microstructural features. Each type of rain may be characterized by a family of two analytical functions-namely, the inverse power law and the gamma distribution for moderate and large values of the distribution index. Calculations of radar reflectivity are performed for these two functions. The great variability of the Z-I and k-I relations with respect to the parameters of the distribution function is shown.
