摘要

摘要本文根据喀山市附近2013-2021年的监测数据，解决了推导全球导航卫星系统接收器测量的大气参数统计特征变异性与对流过程特征之间关系的问题。全球导航卫星系统的监测结果与ERA5再分析计算得出的对流指数（不稳定性的物理和统计参数）进行了比较：上升垂直速度、涡旋生成参数和WMAXSHEAR。结果表明，对流层天顶延迟水平梯度的统计特征在深对流条件下会发生显著变化。这项工作的结果可用于开发在恶劣天气现象业务预报任务中对对流过程进行子卫星监测的技术。

Effects of Strong Convection in Summer on Atmospheric Characteristics Derived from GNSS Monitoring Data

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.
