在这项工作中，我们提出了一组独特的重合和并置的高分辨率观测数据，这些观测数据是从南加州海岸附近收集的机载仪器“模块化空中传感系统”收集的表面流和表面波的方向特性。使用新仪器“DoppVis”获得近地表电流剖面和剪切力的高分辨率观测，该仪器能够捕获低至 128 m 分辨率的水平空间电流变化。该数据集提供了一个独特的机会来研究 1 至 100 km 尺度的海流如何调节表面重力波的体积（例如有效波高）、方向和频谱特性。这些观察是朝着更好地理解亚介尺度过程（例如锋生和锋面停止）的基本物理以及介尺度和亚介尺度动力学之间转变的性质迈出的一步。
In this work we present a unique set of coincident and collocated high‐resolution observations of surface currents and directional properties of surface waves collected from an airborne instrument, the Modular Aerial Sensing System, collected off the coast of Southern California. High‐resolution observations of near surface current profiles and shear are obtained using a new instrument, “DoppVis”, capable of capturing horizontal spatial current variability down to 128 m resolution. This data set provides a unique opportunity to examine how currents at scales ranging from 1 to 100 km modulate bulk (e.g., significant wave height), directional and spectral properties of surface gravity waves. Such observations are a step toward developing better understanding of the underlying physics of submesoscale processes (e.g., frontogenesis and frontal arrest) and the nature of transitions between mesoscale and submesoscale dynamics.
