Radar Derived Storm Characteristics Over Central Greece
Individual storm measurements are obtained from the C-band weather radar, located close to the area of interest, using the cell tracker TITAN (thunderstorm identification, tracking, analysis, and nowcasting). The study aims in analyzing certain storm characteristics over central Greece, as a tool for investigating possible rain enhancement feasibility potential. The objective on this study is two folded: firstly, to analyze and describe storm characteristics and secondly, to identify differences in storm characteristics, structure and their behavior, among distinct synoptic situation patterns. The radar-based storm characteristics are extracted using certain thresholds. Storm characteristics include: storm initiation time, storm duration, storm motion, cloud top, reflectivity, storm volume and storm area. Frequency analyses of the aforementioned findings bring out evidences of the storm characteristics, their extends and limitations, providing thus an integrated view of the experienced isolated storms over the examined area. Moreover, the classification of the storm days reveals certain differences in several storm properties, indicating how isolated storms over central Greece vary under different synoptic situation patterns.
