| 摘 要： | 用诊断与统计方法分析了海洋同化数据和综合海洋大气数据集COADS海面淡水通量.结果显示热带太平洋海面盐度具有年际变化特征,并且和ENSO循环具有内在的联系.从相关统计的角度评估了热带太平洋海面盐度年际变化中海面蒸发与降水、温跃层调整、水平盐分平流等主要因子的不同贡献.

| Abstract: | This paper analyzes oceanic assimilation data and surface fresh water flux from COADS. The results show that sea surface salinity in the tropical Pacific has the feature of interannual variation and it has intrinsic connection with ENSO cycles. Different contribution by major factors to surface salinity interannual variation is further evaluated, such as surface evaporation minus precipitation rate, thermocline adjustment and horizontal advection of salinity. On the interannual time scale, it offers the basis for understanding air-sea interaction in the tropical Pacific in the view of water cycle. |
