On the Prediction of Floods Caused by Rainfall in the Area of Action of the Meteorological Radar “Meteor 735CDP10”

Abstract

Meteorological radar “METEOR 735CDP10” manufactured by “SELEX” (Germany) has been used since 2015 in the operational work of the anti-hail service of Georgia (indication of radar parameters for active exposure to hail dangerous and hail clouds - maximum reflectivity of clouds, height of maximum reflectivity, maximum cloud height, the size of hailstones in the cloud, etc.). Work is carried out in the Kakheti region of Georgia. The working radius of the radar in this case is 100-120 km and covers the entire territory of Kakheti. Season of the anti-hail works continues from April to October. The radar also allows you to determine the intensity of liquid precipitation, and when fixing in its computer program the coordinates of the area where floods often occur during rainfall, it is possibility forecasting these floods. Moreover, out the season of anti-hail works, the radius of the radar can be increased to 200 km and almost cover almost the entire territory of Eastern Georgia. The paper provides a map of points with recurring floods during rainfall in Eastern Georgia and examples of comparing radar data on precipitation intensity with flood data at these points. The accumulation of this information will allow creating an algorithm for flood forecasting in Eastern Georgia based on the results of radar monitoring of the precipitation intensity.
