Detecting and following atmospheric disturbances with a potential to generate meteotsunamis in the Adriatic

The paper deals with a possibility to detect the presence and to follow the movement of an atmospheric disturbance that could lead to a meteotsunami formation. The analysis of the four strongest meteotsunami cases in the past 30 years in the Adriatic shows that three of four cases happened in the south-westerly stream on the front side of a large upper-level trough, whereas in one of the cases large-scale streaming was westerly and north-westerly. It was also noted that all cases occurred during summer months and in each case a convective system was present in the area. That led to the assumption that a convective system is responsible for causing the disturbance leading to meteotsunami formation. Since the convective cells can be recognized and their movement can be followed using the nowcasting tools based on satellite data, a method for predicting the occurrence of meteotsunamis in the Adriatic is proposed.
