The Study of Wind, Wave, Current Extreme Parameters and Climatic Characters of the South China Sea

Based on the advanced wind, wave numerical model of the Laboratory of Geophysical Fluid Dynamics and Numerical Modeling (LAGFD), the current 3-D Princeton Ocean Model (POM), and collected data, Part I hindcasts the strongest 298 tropical cyclones (TCs) affecting the area 19°∼23°N, 113°∼118°E) in the South China Sea (SCS) from 1945 to 1995. It also provides the extreme parameters of wind, wave, current and sea level of the above region, and briefly analyzes the climate characteristics of SCS (15°∼27°N, 108°∼122°E). In part II, the strongest 211 TCs affecting the Wenchang area (16°∼23°N, 105°∼114°E) were hindcast. The marine environmental parameters of wind, wave, current and sea level at 35 points in the research area were provided. The present work puts forward the concept of the conditional extreme value. The conditional extreme values of the point (20°N, 112°E) were also given. The research provides basic data for ocean environmental research and engineering design in this region.
