Observational Evidence of Surface Wave‐Generated Strong Ocean Turbulence

Abstract: By using an acoustic Doppler velocimeter mounted on the seabed of the continental shelf of the northern South China Sea, high frequency velocity fluctuations were measured for 4.5 days. The turbulent kinetic energy dissipation rate was estimated. During the observation, the strong ocean response to Typhoon Rammasun was recorded to compare the turbulent characteristics before and during the typhoon. The results show that the turbulence near the seabed is mainly generated by the tidal current shear and exhibits … Show more

“…Typhoon Rammasun passed through the observation site during the ocean turbulence experiment from 13 to 21 July 2014 (Ma et al, 2020;Qiao et al, 2016), and the maximum wind speed of ∼25 m/s was recorded. During this experiment, a bottom-mounted acoustic wave buoy (acoustic wave and current profiler, AWAC, Nortek, 1 MHz) was used to observe the surface wave.…”

“…Fortunately, the pressure sensors of wave buoy recorded the wave height information. More details can be found in Qiao et al (2016) and Ma et al (2020). In the current study, the significant wave height, the peak wave period, and the mean wave direction were used to analyze and validate the fifth generation ECMWF reanalysis product (ERA5 reanalysis).…”

“…The Qiao theory analytically expresses the wave-induced mixing due to wave orbital motion in terms of Bv, the coefficient for turbulent diffusion due to wave turbulence, which is a function of wavenumber spectrum. Bv behaviors were then confirmed by the following laboratory experiments (Babanin & Haus, 2009;Dai et al, 2010;Ma, Babanin, & Qiao, 2020;Ma, Dai, et al, 2020), in-situ observations (Matsuno et al, 2006;Huang et al, 2012;Sutherland et al, 2013) and numerical modeling (Babanin & Chalikov, 2012;Ghantous & Babanin, 2014a, 2014bGuo & Shen, 2014). In order to reveal the mechanism of wave-induced mixing, Qiao et al (2016) designed scientific in-situ experiments in the northern South China Sea and provided solid experimental evidence of wave-turbulence interactions in the ocean by means of direct field measurements, for the first time.…”

“…As a result, simulation performance of the sea surface temperature, especially in the warm-pool and cold-tongue in the equatorial Pacific, was improved in their climate model. Recently, based on observation by means of laser altimeters under Tropical Cyclone Olwyn in the Indian Ocean, the sea spray volume flux was analyzed, and new parameterizations are proposed in terms of both wind speed and surface-wave properties (Ma, Babanin, & Qiao, 2020;Ma, Dai, et al, 2020;Xu, Voermans, Liu, et al, 2021;Xu, Voermans, Ma, et al, 2021), which reduced the uncertainty down to one order of magnitude.…”
