我国东部黑潮海域海表风速和海表温度变化特征

The Variation Characteristics of the Sea Surface Wind Speed and SST in Kuroshio Sea Area of Eastern China

通过AVHRR资料和Quick-SCAT资料分析了我国东部海域特殊的海气相互作用特点,并对我国东部黑潮海域的海表风速和海表温度时间分布特征和关系进行了分析。结果表明,我国东部海域黑潮海区海表温度与海表风速之间存在特殊的正相关关系,黑潮海域海表温度与海表风速的冷暖分布均呈现一一对应关系,即大风速区位于暖脊上,而小风速区出现在冷槽上空。这种正相关关系是影响我国东部海域海气相互作用的重要因素,且这种正相关关系随着季节和年份的不同有所变化,在冬、春季节表现最为明显,且春季强于冬季。

The air-sea interaction characteristics in sea area of eastern China were analyzed through AVHRR data and Quick-SCAT data, the temporal distribution features and relationship between sea surface wind speed and SST in Kuroshio sea area of eastern China were analyzed. The results showed that there was a positive correlation between sea surface wind speed and SST, the distribution of SST and sea surface wind speed indicated corresponding relation, namely the large wind speed area was located on the warm ridge, while the small wind speed area appeared in the cold trough. The positive correlation was an important factor influencing air-sea interaction in eastern China sea, and this correlationship was related with season and year, especially in winter and spring, spring was stronger than that in winter.
