A Case Study of Rural Area Hail Storm in Yomra, Trabzon, on August 31, 2017
Abstract
On August 31, 2017, a hail storm occurred in rural area in Yomra District of Trabzon Province. The hail storm occurred during the harvest season, and it did not cause big losses on hazelnut production because hazelnuts had been fully grown. The hail storm was recorded, and some of hail accumulations had been photographed by a mobile phone. Diameters of hail were approximately 1.5 cm. In this study, the hail storm event is analysed by satellite and weather radar products that obtained from Turkish State Meteorological Service. Also, the radar data analysed by Thunderstorm Identification, Tracking, Analysis and Nowcasting (TITAN) software which is used for the first time in the analysis of meteorological events in Turkey. Here, it was discussed that the storm cell with 62.5 dBZ reflectivity value is whether a “supercell” or not.
