| Popis: | The report deals with the study of hail clouds using the MRL-5 meteorological radar. The determination of the microphysical parameters of hail clouds is carried out using the dual-wavelength radar method for λ = 3.2 and 10 cm. It is known that the radar reflectivity of precipitation depends on many factors, but the results of calculations and their comparison with experimental data showed that the radar reflectivity of a population of hail particles is mainly determined by their cubic mean size ( d ¯ 3 ) and concentration (N). For the case of two wavelengths, there is a system of equations that relate the radar reflectivity to the cubic mean size and the concentration of hail in the cloud (when parameterizing the remaining characteristics). In other words, for each thermodynamic regime of hail growth and melting, there will be a different set of coefficients of the system of equations. The report calculates the microstructure parameters for a real hail cloud. |
