Equatorial Pacific Ocean Current Instabilities

该项目是一项名为热带不稳定波实验(TIWE)的协调研究的组成部分。P.I.将在赤道经度140°W附近部署一个由四个海流测量系泊设备组成的阵列，配备向上俯视的声学多普勒海流剖面仪(ADCP)，能够以高垂直和时间分辨率绘制近地表海流的轮廓。还提出了一种热敏电阻链式系泊装置。P.I.将与TIWE的其他组成部分以及现有的NOAA海流和温度停泊处合作，试图计算动量通量、雷诺热通量辐合、正压不稳定产生的能量和背景流上升的平衡。关于背景平均流的信息也将根据年变率进行分析。

This project is a component of a coordinated study called the Tropical Instability Waves Experiment (TIWE). The P.I. will deploy an array of four current measurement moorings, at the equator near longitude 140 deg W, instrumented with upward- looking Acoustic Doppler Current Profilers (ADCP), capable of profiling the near-surface currents with a high degree of vertical and temporal resolution. One thermistor chain mooring is also proposed. In collaboration with other TIWE components, and existing NOAA current and temperature moorings, the P.I. will attempt to calculate balances of momentum flux, Reynolds heat flux convergence, energy production by barotropic instability, and background current upwelling. Information on background mean currents will also be analyzed in terms of annual variability.
