EXAMINING A COMPREHENSIVE DATASET CONTAINING THOUSANDS OF FREAK WAVE EVENTS. PART 2 - ANALYSIS AND FINDINGS

摘要

This paper concerns the analysis of a very large, quality-controlled dataset of raw wave measurements. It directly follows from paper I, as part of work undertaken for the CresT (Cooperative Research on Extreme Seas and their impacT) Joint Industry Project (JIP), and describes the various analyses performed on the dataset. In particular numerous freak wave events are observed and various analyses are performed to gain an insight into conditions that are conducive to their formation. The examination of probability distributions, spectral and temporal parameters, degree of focusing and environmental conditions that lead to freak waves is performed and the findings are presented.
