Radar Methods for Determination of Hail Microstructure

The currently existing radar methods for determining the microphysical characteristics of hail require constant improvement. The purpose of this work is to consider radar methods for determining the hail microstructure (two-wave and single-wave methods). The result of long-term studies of the microstructural characteristics of hail growing in a cloud is presented. A comparison is made of the results of determining the hail size by the two considered methods. The repeatability of some parameters of real hail spectra is determined. More than 600 hail clouds of various intensities that developed over the territory of the KBR and adjacent areas were studied. Based on the results of many years of research, a curve was constructed that describes the correlation between concentrations and the average cubic hail diameter in the growth zone at the moment of maximum development of convective cells.
