Abstract

The properties of rogue waves in shallow water are analyzed based on records of sea surface elevation in Tallinn Bay, the Baltic Sea, measured at the water depth 2.7 m from 17 June to 1 July 2009 at a recording frequency of 5 Hz. The data set contains rogue waves, which occur in relatively calm weather conditions. Rogue waves are identified as those, whose wave height is at least twice larger than the significant wave height. The results obtained by both methods up-crossing and down-crossing are analyzed and compared. The statistics of rogue wave heights is studied together with the statistics of rogue wave crests and rogue wave troughs.
