摘      要：As concluded from physical theory and laboratory experiment,it is widely accepted that nonlinearities of sea state play an important role in the formation of rogue waves;however,the sea states and corresponding nonlinearities of real-world rogue wave events remain poorly *** rogue waves were recorded by a directional buoy located in the East China Sea during Typhoon Trami in August *** study used the WAVEWATCHⅢmodel to simulate the sea state conditions pertaining to when and where those rogue waves were observed,based on which a comprehensive and full-scale analysis was *** the perspectives of wind and wave fields,wave system tracking,High-Order Spectral method simulation,and some characteristic sea state parameters,we concluded that the rogue waves occurred in sea states dominated by second-order ***,third-order modulational instabilities were suppressed in these events because of the developed or fully developed sea state determined by the typhoon wave *** method adopted in this study can provide comprehensive and full-scale analysis of rogue waves in the real *** case studied in this paper is not considered unique,and rules could be found and confirmed in relation to other typhoon sea states through the application of our proposed method.
