Sažetak
Croatia is because of his location in the mid latitudes of the Northern Hemisphere, especially in the summer months exposed to the frequent occurrence of severe thunderstorms and hail, especially in the continental part where modest climate and rich soil enable agricultural production. In the 1960s, aiming to protect agricultural production and reduce damage, a hail suppression system was introduced in that area. In this study, are used observed hail and damage data in the 1981-2012 period along with the hailpad data from 2002-2012 period collected on hail suppression stations (May –September). To determine areas with with greater hail risk, two spatial analyses are made. First one on the base of hail and damage data on hail suppression stations (1981-2012) calculate “hail threatening index” as an empirical function of average number of days with hail and damage for 136 quadrants (9 km x 9 km) that fully or partially cover this area. In addition, empirical orthogonal function analysis is performed on the kinetic energy hailpad data (2002-2012), in order to determine quadrants/areas with greater average kinetic energy. This paper present analysis of hail parameters and reveal the areas with greater hail and damage risk in the continental part of Croatia.
