摘要

Abstract

Wave fields of the South China Sea (SCS) from 1976 to 2005 were simulated using WAVEWATCH III by inputting high-resolution reanalysis wind field datasets assimilated from several meteorological data sources. Comparisons of wave heights between WAVEWATCH III and TOPEX/Poseidon altimeter and buoy data show a good agreement. Our results show seasonal variation of wave direction as follows: 1. During the summer monsoon (April–September)

waves from south occur from April through September in the southern SCS region

which prevail taking about 40% of the time; 2. During the winter monsoon (December–March)

waves from northeast prevail throughout the SCS for 56% of the period; 3. The dominant wave direction in SCS is NE. The seasonal variation of wave height H s in SCS shows that in spring

H s ≥1 m in the central SCS region and is less than 1 m in other areas. In summer

H s is higher than in spring. During September-November

influenced by tropical cyclones

H s is mostly higher than 1 m. East of Hainan Island

H s>2 m. In winter

H s reaches its maximum value influenced by the north-east monsoon

and heights over 2 m are found over a large part of SCS. Finally

we calculated the extreme wave parameters in SCS and found that the extreme wind speed and wave height for the 100-year return period for SCS peaked at 45 m/s and 19 m

respectively

SE of Hainan Island and decreased from north to south.
