两者的风速相关系数为0。86，平均偏差是- 1。50 m / s，均方根误差为1。这表明QuikSCAT散射计在南海的地面风资料是非常有用的。利用QuikSCAT月平均地面风资料分析南海气候特征。结果表明：南海地面风场具有以下特征：(1)南海季风随季节变化，10月至次年3月以东北风为主；从6月到8月，以西南为主，而4月、5月和9月是过渡期。(2)平均风速值中心有两个，一个位于南海以南108°E，10°N附近，另一个位于台湾海峡附近，其位置和强度随季节变化。
Comparisons are firstly made between QuikSCAT sea surface wind data of South China Sea from the Asia-Pacific Data-Research Center and surface wind observations from Xisha observation station established by institute of South China Sea Oceanography,Chinese Academy of Science during April 6-December 31,2008. The wind speed correlation coefficient between the above two is 0. 86,the mean deviation is- 1. 50 m / s,and the root mean square error is 1. 71 m / s,which suggests that QuikSCAT scatterometer surface wind data in South China Sea are very useful. And then,the monthly mean QuikSCAT surface wind data are used to analyze climatic characteristics of South China Sea. The results show that the surface wind field in South China Sea has the following features:( 1) The South China Sea monsoon changes with seasons,that is,from October to next March the northeaster prevails; from June to Au-gust,the southwester prevails,While April,May and September are transitional periods.( 2) There are two average wind speed value centers: one is located near the south 108 °E,10 °N of South China Sea, while the other near the Taiwan Strait,whose site and intensity change with seasons.
