Temporal and spatial scaling of dissipation under non-breaking surface waves

This dataset is associated to the NSF OCE/Physical Oceanography funded project “Laboratory Investigation of Turbulence Generation by Surface Waves”. There are three papers in preparation that will refer to data contained within this archive. The overarching goal of this project was to address a significant knowledge gap regarding the turbulent dissipation of non-breaking surface waves. To accomplish this, a comprehensive study in the SUrge-STructure-Atmosphere-INteraction (SUSTAIN) wind-wave laboratory at the University of Miami was conducted. A combination of established measurement approaches (Particle Image Velocimetry (PIV) and Vertical Microstructure Profiler (VMP)) and new technologies (Optical Turbulence Sensor (OTS)) have been used carry out the measurements of energy and temperature dissipation under non- breaking waves. Specifically, these are the data originally collected during a series of lab experiments in SUSTAIN in Nov, 2017. All data are based on standardized lab-based observations. Over the 1-month study, TKE and temperature dissipation rate was measure in a variety of conditions, ranging from young waves (high wind speed to wave speed ratio) to old waves (low wind speed to wave speed ratio). The result showed that the short surface waves played a critical role in the generation of turbulence under the nonbreaking waves. This turbulence was modulated by the long waves. These data provide empirical evidence for the parameterization of dissipation related nonbreaking waves.

本项目的核心目标，在于填补非破碎表面波湍流耗散领域的重大研究空白。为此，研究团队在迈阿密大学“浪-结构-大气相互作用（SUrge-STructure-Atmosphere-INteraction, SUSTAIN）”风浪实验室开展了全面的实验研究。
研究结合使用了成熟的测量手段（粒子图像测速仪（Particle Image Velocimetry, PIV）与垂直微结构剖面仪（Vertical Microstructure Profiler, VMP））与新型光学湍流传感器（Optical Turbulence Sensor, OTS），对非破碎波条件下的能量与温度耗散开展了测量。具体而言，本数据集的数据源自2017年11月在SUSTAIN实验室开展的一系列室内实验。
所有数据均基于标准化的实验室观测结果。在为期1个月的实验周期内，研究团队在多种工况下测量了湍流动能（Turbulent Kinetic Energy, TKE）耗散率与温度耗散率，工况涵盖从年轻波（风速与波速比值较高）到老成熟波（风速与波速比值较低）的全范围。
实验结果表明，短尺度表面波在非破碎波条件下的湍流生成过程中发挥了关键作用，而该湍流过程受长尺度波浪调制。本数据集为非破碎波相关耗散过程的参数化方案提供了实验依据。
