Abstract
Tasks which require information about energy characteristics of rains and methods for acquiring this information are briefly reviewed. A technique is suggested for estimating the kinetic energy transferred by hydrometeors based on microstructural characteristics of rainfall obtained with an OPTIOS optical precipitation gage. The technique is tested with measurement data received during a heavy rainfall occurred in Tomsk on July 22, 2023. The influence of different microstructural parameters on the amount of kinetic energy brought by raindrops to the underlying surface is analyzed. The results are compared with the values obtained by simplified methods. It is concluded that the capabilities of the optical precipitation gage make it a useful tool for solving tasks where accurate assessments of rainfall energy characteristics are required.
期刊介绍：
Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
