摘要
Abstract
Based on ERA-40 data ,this paper analyzed the spatial distribution of two modes of wind and wave height of the South China Sea by EOF method,which calculated the spatial distri-bution,long-term trends and mutation phenomenon of surface wind speed and wave height of South China Sea during 1957—2002.The results showed that the first mode of wind and wave field of South China Sea has a good state of similarity,the second mode has shown different char-acteristics.Analysis of the first mode of time coefficient also showed that wind and wave height variation has a significant positive correlation and the response of the wave height has certain hys-teresis.Wind and wave field during 1973—2002 had a downward trend,but the downward trend of wave field was more obvious.关键词
