Abstract:

To describe both the way in which a wave spectrum grows and the growth processes of realistic wave conditions, the dependence relationship between the spectrum parameters and wind parameters must be obtained.Based on data measured in 2010 by a Wave Rider buoy, which was deployed in the South China Sea at coordinates 21.89°N, 115.13°E, we evaluated the wave spectrum in the sea area when affected by three typhoons: Conson, Chanthu, and Megi.The Joint North Sea Wave Project spectrum was parameterized based on the observed wave spectrum.We proposed a spectrum with three parameters: the dimensionless lowest moment of the spectrum, dimensionless peak frequency, and spectrum width.The relationships between these spectral parameters and the dimensionless fetch were also discussed.

Key words: energy wave spectrum|northern South China Sea|typhoon
