Rezumat

Extreme climatic phenomena such as strong winds or hail can pose immediate threats to agricultural crops, and the damage that can occur, depending on the phenophase of the crop, can be significant. The consequences of annual crops manifest themselves over the course of the year, whereas the consequences of polycarpic species (vineyards, orchards) can extend over a longer period of time. In the summer of 2021, a series of storms with heavy winds and hail were noticed over a fruit-growing region in NE Moldova (Romania), causing damage to over 400 ha. These phenomena overlapped during fruit ripening (approximately one month before picking), but the damage was not only to the fruits, but also to the trees in the young plantations, with injuries occurring on the tree trunks. In this case study, the extreme meteorological phenomena will be outlined using gridded data (ERA5) and images with the kinetic energy of the cell that manifested itself over the study area. Given that the state of the vegetation can be tracked using satellite images (via indices that monitor chlorophyll activity), the purpose of this study is to highlight the areas affected by extreme phenomena using satellite remote sensing and GIS techniques.
