The Statistical Characteristics of the Radar Echo as a Function of the Dynamic Processes and Microstructure of the Meteorological Entity (Sviaz Statisticheskikh Kharakteristik Radiolokatsionnogo Signala S Dinamicheskimi Protsessami I Mikrostrukturoi Meteoob''ekta)

摘要

This article treats the development of a statistical radar method. It contains the entire theory of the method and indicates the possibilities of radar measurement of the wind speed and the microcharacteristics of precipitation. Mathematical formulas are given for using the spectrum of the radar echo to determine the average rate of power dissipation epsilon in turbulent flow, the wind shear, the hydrometeor size distribution, etc. The observational technique and the apparatus are described. Observational data are presented for clouds of various types whose epsilon-values have been calculated. The paper also states the results of wind observations and indicates the feasibility of separating the directional pulsations of the wind from its velocity pulsations. The article contains the results of radar measurement of hydrometeor size distribution, precipitation intensity, etc. The lines of further develpment of statistical radar methods are noted. (Author)
