Wave Characteristics in Northeast Coastal Waters of Zhoushan Island Under the Influence of Winter Monsoon

Abstract

Waves at 12 m water depth in the northeast coastal waters of Zhoushan Island were measured from November 2014 to February 2015, and the characteristics were described. The study showed that the significant wave height varied from 0.08 to 1.35 m with the average of 0.36 m during the winter monsoon period, but the maximum of the maximum wave height is close to the maximum value of some typhoon waves of the same place. The monthly main wave direction varied from ENE to N to NE to ENE. Relatively high correlations exist between some wave parameters and relationships between them were identified. Most of the waves have a bimodal spectrum and the influence of monsoon on waves is intermittent.
