在这项研究中，三个垂直速度包括在一个一维（1D）海洋模式的东南亚时间序列研究站在中国南海的案例研究。垂直速度由三个过程组成，即，Ekman泵（WEK）、涡泵（WEP）和背景上升流（WBK）。WEK的量化遵循经典的Ekman泵浦理论。利用Argo观测资料和测高资料对WEP进行了定量分析，其基本机制与斜压模态（以第一模态为主）一致。WBK与背景环流有关，由长期热量收支平衡估算。技能评估表明，所有三个过程的情况下表现最好。研究证实了具有三种垂直速度的一维模式的能力，它可以再现垂直方向上的一般结构和温度变化。
In this research, three vertical velocities were included in a one-dimensional (1D) ocean model for a case study of the SouthEast Asian Time-Series Study station in the South China Sea. The vertical velocities consisted three processes, i.e., Ekman pumping (WEK), Eddy pumping (WEP), and the background upwelling (WBK). The quantification of WEK followed the classical Ekman pumping theory. The WEP, whose underlying mechanism was consistent with the baroclinic modes (dominated by the first mode), was quantified by Argo observation and altimetry data. The WBK, related with the background circulation, was estimated from the long-term heat budget balance. The skill assessment indicated that the case with all three processes performed best. The study confirmed the capability of the 1D model with three types of vertical velocities, which can reproduce the general structure and variation of temperature in vertical direction.
