Mean composite anomalies in surface and average 100 first meters of EKE for upwelling or downwelling IEKWs events.

Mean composite anomalies in surface and average 100 first meters of EKE for upwelling or downwelling IEKWs events. Anomalies refer here as the difference between the mean over the first 20 days of each individual selected event and the long-term mean (1993-2018). The bar of differences (upwelling/downwelling vs CR-long run) in % are averaged in the first 20 or 40 days. The error bars (low and high) denote the confidence intervals at 95% based on Student t test.

针对上升流或下降流型的强涡动动能波（Intense Eddy Kinetic Waves, IEKWs）事件，计算其表层及前100米平均涡动动能（Eddy Kinetic Energy, EKE）的合成异常。此处的异常值定义为各单个选定事件的前20天平均值与1993-2018年长期平均值的差值。以百分比表示的差值柱（上升流/下降流事件与CR-long run的对比）在事件发生后的前20天或前40天内完成时间平均。误差棒的上下限代表基于Student t检验得到的95%置信区间。
