摘　　要：利用由美国宇航局物理海洋学数据分布存档中心发布的2007—2011年CCMP风场资料,针对西北太平洋海面风场的季、月、日变化特征进行了分析。结果表明:西北太平洋海面风场具有明显的季、月变化特征,夏季盛行西南风,风向多变,风速最低;冬季盛行东北风,风速偏高。大风频发区域位于南海海域、台湾海峡和日本岛以东,且冬季发生频率明显高于其他3个季节。此外,还利用获取到的2014年8月海面自动观测站和9月海上探空资料对相应月份的风场特征进行细化分析,表明8月洋区盛行西南风,而9月西南风逐渐消退,风速减小,变化特征与相应月份CCMP的海面风分析相符。The seasonal, monthly and daily characteristics of sea surface wind field in the northwestern Pacific are analyzed based on the high resolution CCMP satellite dataset. The results show that： the sea surface wind in the northwestern Pacific displays obvious seasonal and monthly variation characteristics. The southwester prevails in summertime with variable wind direction and the lowest velocity, while the northeaster does in winter with higher speed. The area of frequent gales mainly located in the South China Sea, Taiwan Strait and east of Japan Island. The frequency in winter is significantly higher than the other three seasons. The automatic observation data in August 2014 and GPS data in September are analyzed to validate the result of the above. The result proves that the southwest still prevailed in August, but decreased in September.
