| 摘 要： | 应用热带太平洋上层XBT温度资料,分析研究了西太平洋暖池区(0°～16°N,125°～145°E)上层海洋的变化特征以及与西太平洋次表层海温场之间的关系.研究表明,西太平洋暖池区的垂向温度存在显著的年际变化,尤其在次表层(120～200m)的变化最为明显.西太平洋暖池区的次表层冷暖信号明显早于西太平洋次表层的海温异常.分析发现,西太平洋暖池区的海温异常是导致整个西太平洋次表层海温场变异的关键区,当西太平洋暖池区的次表层冷暖信号加强时,3～4个月后西太平洋海温场出现大范围的冷暖异常.

| Abstract: | The relationship between the characteristics of the upper ocean change in the West Pacific warm pool region (0°~16°N,125°~145°E) and the subsurface ocean temperature field in the West Pacific is analyzed by XBT temperature data in the upper tropical Pacific.The research results show that the annual change of the vertical distribution of the ocean temperature in the West Pacific warm pool region is notable and particularly that in subsurface layers (120~200 m) is most obvious.The anomalous change of the ocean temperature signals in the warm pool earlier than that of the subsurface in the West Pacific,and the former is leading to the key region of the subsurface ocean temperature variation in the West Pacific.The subsurface ocean temperature in the West Pacific anomalous change will appear after 3~4 months when the anomaly signals of the subsurface ocean temperature enhance in the warm pool region. |
