摘要

夏威夷群岛以西背风逆流区流系复杂，是中尺度涡高发区，该海域中尺度涡活动对大尺度环流变化、海气交换以及海洋生物分布等具有重要意义。利用1993—2020年的再分析数据，研究了夏威夷群岛背风逆流区涡动能的年际变化特征及其机制。根据涡动能分布情况，将夏威夷群岛以西背风逆流区分为2个区域（离岛区域和近岛区域）开展研究，主要结论如下：①离岛和近岛区域涡动能均有显著的年际变化，近岛区域超前离岛区域涡动能变化。超前12个月时，与离岛涡动能相关系数最大为0.57。②涡动能的年际变化主要受正压不稳定、斜压不稳定、平流和风应力做功调控。涡动能收支诊断分析发现离岛区域涡动能的年际变化主要受斜压不稳定变化控制，近岛区域涡动能年际变化主要受风应力做功变化控制。③涡动能年际变化受大尺度年际信号调控。离岛区域涡动能年际变化与太平洋年代际振荡信号指数显著相关，超前太平洋年代际振荡信号指数10个月时相关系数最大为0.85。近岛区域涡动能年际变化超前太平洋年代际振荡信号指数2个月时，相关系数最大为0.40。

Abstract

The Hawaiian Lee Countercurrent region is characterized by high occurrence of mesoscale eddies and complex flows. The activity of mesoscale eddies in this region is critical for the oceanic and atmospheric circulations, sea-air exchange, etc. The interannual variability of the Eddy Kinetic Energy (EKE) and its mechanisms in this region were investigated using reanalysis data from 1993 to 2020. According to the EKE distribution, two regions were selected, namely off-island and near-island. The results showed the following: ① The interannual variation of the EKE is significant in both the off-island and near-island regions. The EKE variation in the near-island region leads that in the off-island region by 12 months, with a maximum correlation coefficient of 0.57. ② The interannual variation of the EKE is mainly regulated by baroclinic instability, barotropic instability, transport, and wind stress work. Analysis of the EKE budget revealed that the interannual variation of the EKE in the off-island region is mainly controlled by baroclinic instability variation, whereas that in the near-island region is mainly controlled by wind stress work. ③ Interannual variations of the EKE are modulated by large-scale signals. The interannual variation of the EKE in the off-island (near-island) region is significantly correlated with the PDO index, leading by 10 (2) months, with a maximum correlation coefficient of 0.85 (0.40).

Key words： The Hawaiian Lee Countercurrent region; Eddy Kinetic Energy (EKE); Interannual variation; Baroclinic instability; Barotropic instability
