Rainfall erosivity is an indicator of the potential of precipitation to generate erosion processes and is essential for understanding the climatic vulnerability of a region. This article aims to develop a model for evaluation the average annual and seasonal rainfall erosivity in areas with different climatic and orographic conditions. The studied area covers the regions of Lovech and Kardzhali, which are characterized with high intensity of erosion processes and high erosion risk. To achieve the goal of the study ...

The aim of the study is to present variation of days with hail precipitation in different regions of Bulgaria and seasonal synoptic classification of such type of extreme events. Examined period is 1991 – 2020. Time-space distributions of days with hail events, detected in at least one station from meteorological network of the National Institute of Meteorology and Hydrology are presented, as well as the regime of wide-spread hail events. The hail precipitation which are detected in at least 4 districts in Bulgari...
