Abstract
The paper solves the problem of deriving the relationship between the variability of statistical characteristics of atmospheric parameters measured by GNSS receivers and the characteristics of convective processes based on monitoring data near the Kazan city for 2013–2021. The GNSS monitoring results are compared with the convective indices, which are physical and statistical parameters of instability, calculated from ERA5 reanalysis: upward vertical velocity, vortex generation parameter, and WMAXSHEAR. Statistical characteristics of the horizontal gradient of the zenith tropospheric delay are shown to significantly change under conditions of deep convection. The results of the work can be used to develop a technique for sub-satellite monitoring of convective processes in the tasks of operational forecasting of severe weather phenomena.
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.
