Short summary
Meteotsunamis are long waves created by atmospheric disturbances travelling over the sea. These waves can be hazardous in rare cases. Their occurrence in the Baltic Sea has been poorly known, which is why we examine century-long sea level records from the Gulf of Finland to identify these waves. In total, 121 potential meteotsunamis were found. The strong connection between meteotsunami occurrence and lightning observations indicates that meteotsunamis in this region occur during thunderstorms.
