摘要

Several hail diagnostic and detection methods were applied on the three-dimensional radar reflectivity data. Nominal resolution of the data was lkm in the horizontal as well as in the vertical direction. Most methods use a certain value of the reflectivity as a threshold and combine the information of the temperature profile of the atmosphere to assess the depth of the column with freezing temperatures, an important parameter in the detection algorithms. The temperature profile was taken from the radiosonde data. We have produced a map, showing the 5 year average number of events with probable hail fall over each of I km squares covering the NE Slovenia. When sufficiently long data series is used to prepare the climatology it can also be used to provide the probability of hailstorm events in the future. The hail probability estimate based on this study should be used with caution, but can nevertheless present valuable additional information to ease decision making in case of crop and vines insurance and physical protection with nets.
