Abstract
In this work, the optimal parametrization of a mesoscale meteorological model is sought based on a comparative analysis of model forecasts and measurement results on temperature inversions in the planetary boundary layer of the atmosphere of the Moscow megapolis. The WRF–ARW model was tested with several different combinations of physical parameterizations to assess the prediction quality for temperature inversion parameter over Moscow. The dynamic and statistical characteristics of temperature inversions have been calculated and analyzed in selecting criteria for the comparisons. The terms of temperature inversion destruction are estimated depending on the inversion type. The measurement results on temperature profiles in the layer of up to 1 km obtained by an MTP-5 passive microwave profiler from 2018 to 2021 served as the data source. One MTP-5 in the north of Moscow was used to tune the model parameters, and another one on the east of Moscow was used for validation. The comparison results show that the model can be optimally tuned using a set of several parameterization variants.
期刊介绍：
Izvestiya, Atmospheric and Oceanic Physics is a journal that publishes original scientific research and review articles on vital issues in the physics of the Earth’s atmosphere and hydrosphere and climate theory. The journal presents results of recent studies of physical processes in the atmosphere and ocean that control climate, weather, and their changes. These studies have possible practical applications. The journal also gives room to the discussion of results obtained in theoretical and experimental studies in various fields of oceanic and atmospheric physics, such as the dynamics of gas and water media, interaction of the atmosphere with the ocean and land surfaces, turbulence theory, heat balance and radiation processes, remote sensing and optics of both media, natural and man-induced climate changes, and the state of the atmosphere and ocean. The journal publishes papers on research techniques used in both media, current scientific information on domestic and foreign events in the physics of the atmosphere and ocean.
