Results of linear ocean model experiment for: Dual wave energy sources for the Atlantic Niño events identified by wave energy flux in case studies

These are sensitivity experiments designed by manipulating the wind forcing that drives the linear ocean model to investigate the difference in equatorial waves in 1999, 2019, and 2021. 

Methods
Three forcing regions are marked as R1 (the western equatorial Atlantic region), R2 (the whole equatorial Atlantic region), and R3 (the off-equatorial region).  Selecting one region where the zonal forcing is applied and elsewhere it is eliminated to initiate the event in the three selected years respectively. Thus one group of the experiments for a certain selected year includes five scenarios marked from T0 to T4, where T0 is the reference run, T4 is the scenario excluding the zonal forcing in the whole selected forcing domain and other numbers indicate the selected region where the zonal forcing is still applied. In each scenario, we integrated the LOM for two years from the initial condition by the reference run (T0) at the beginning of the selected year to excite the 1st-4th BCMs independently.

本数据集包含一系列敏感性试验，通过调控驱动线性海洋模型(linear ocean model)的风场强迫，旨在探究1999年、2019年与2021年赤道波动的差异。

试验方法
共设置3个强迫区域：R1为赤道大西洋西部海域，R2为整个赤道大西洋海域，R3为赤道外海域。针对上述三个选定年份，分别选取其中一个区域施加纬向风强迫，其余区域的强迫则被移除，以此触发对应海洋事件。因此，针对某一选定年份的一组试验共包含T0至T4共5个情景：其中T0为对照试验(reference run)，T4为在整个选定强迫区域内移除纬向风强迫的情景，其余编号则代表保留对应区域纬向风强迫的情景。在每个情景中，我们以参考试验（T0）在选定年份年初生成的初始场为起点，对线性海洋模型(LOM)进行为期两年的积分，以此独立激发第1至第4阶斜压海洋模态(BCMs)。
