| 摘 要： | 将渤、黄、东海海表面温度作为一个整体场,研究其年际变化特征,并进一步探讨其与东亚季风场年际变化特征的关系.利用美国NOAA极轨卫星中的高级甚高分辨率辐射计(AVHRR)反演的海表面温度资料,采用EOF方法分冬夏两季对渤、黄、东海SST的年际变化做了初步分析,发现渤、黄、东海SST存在显著的年际变化周期,冬季存在5 a的显著变化周期,夏季存在4 a的显著变化周期,并研究了东亚季风场的年际变化对SST变化产生的影响.发现冬季日Nin0年东亚寒潮活动弱于La Nina年,El Nino年SST较La Nina年偏高;夏季El Nino.年东亚夏季风活动弱于La Nina年,El Nino年SST较La Nina年偏低,但是趋势不如冬季明显.

| Abstract: | In order to study on the characteristic of the inter-annual variation of the SST in the Bohai Sea, Yellow Sea and East China Sea as a whole, the relationship between the characteristic of the inter-annual variation of SST and the East-Asian monsoon was probed. Using EOF method with the SST data from Advanced Very High Resolution Radiometer (AVHRR) in the NOAA polar-orbiting satellite, the significant inter-annual variation in the Bohai Sea, Yellow Sea and East China Sea has been analyzed in winter and summer. We found that SST has a notable variation period of 5 years in winter and 4 years in summer. And we explored the effect of the inter-annual change of the Asian monsoon field on the change of SST and found that in winter El Ni?o year has a weaker Asian winter monsoon than La Ni?a year while SST is higher in EL Ni?o year than that in La Ni?a. In summer, the Asian summer monsoon in EL Ni?o year is weaker than that in La Ni?a year and so is SST but not as obvious as in winter. |
