摘　　要：利用CCMP风场,计算了1988～2009年南中国海海表风速的变化趋势以及变化趋势的区域性差异、季节性差异。结果表明,1988～2009年,南中国海的海表风速整体上以0.038 6m/(s·a)的速度显著性逐年线性递增;近22年期间,南中国海海表风速的变化趋势表现出较大的区域性差异,大部分海域的海表风速呈显著性逐年线性递增趋势,为0.03～0.15m/(s·a),呈显著性线性递减的趋势分布于台湾东部和菲律宾周边的一些零星海域,无显著性变化趋势的海域分布于南中国海12°N附近一带状海域、中南半岛东南海域一椭圆形海域;南中国海海表风速的变化趋势表现出很大的季节性差异。The cross-calibrated, multi-platform （CCMP） wind field data were used to analyze the linear trend of sea surface wind field in the South China Sea from 1988 to 2009. The characteristics of regional and seasonal differences of linear trend of wind speed were also calculated. Results find that the sea surface wind speed in the South China Sea has an obvious increasing trend as a whole, of about 0. 038 6 m/（s · a）, that there is obvious regional differences of the linear trend of sea surface wind speed in the South China Sea, that most of the waters has significant increasing trend of 0.03--0.15 m/（s · a） ,that linear trend of sea surface wind speed in the South China Sea has obvious seasonal differences,and that linear trend of sea surface wind speed in differenct waters were dominated by different seasons.
