Methodology of the Use of Meteorological Radar MMR50 and Other Meteorological Systems for Purpose Determination Risk of Flash Floods
Author:
Abstract: This article aims to determine the resulting risk of flash floods on the basis of outputs of meteorological radar MMR50, numerical weather prediction model GFS, aerological radiosonde Prostejov, Flash Flood Guidance and Integrated Warning Service System of Czech Hydrometeorological Institute. This methodology is used for the emergency management of individual municipalities with extended powers of the Zlín Region. This article also includes a description of the basic principles of radar rainfall measurements and all radar products that are part of software equipment of the meteorological radar MMR50. The first chapter focuses on basic description of meteorological radar, the principle of transfer of radar reflectivity on the intensity of precipitation, including a description of radar outputs. Use of radar outputs for measurement and prediction of convective precipitation is demonstrated on historical weather conditions of July 24, 2015, when local flash floods were in the central part of the Zlín region. In the last chapter, the theory of methodology is described with use of meteorological sources for measuring and predicting thunderstorms. The theory is verified in the same situation as in the previous case study. Outputs of methodology are compared with the station and other meteorological data in the Zlin Region.
