Dual‐Pathway Influence of Submesoscale Processes on the Southern Ocean Meridional Overturning Circulation

Jinchao Zhang, Zhiwei Zhang, Yinxing Liu, Qingguo Yuan et autres

Abstract The Southern Ocean meridional overturning circulation (MOC) play a crucial role in the global ocean water mass and heat redistribution, greatly modulating the earth climate variation. Although mesoscale eddies are known as an important component of the residual‐mean MOC that typically …

Features of Kinetic Energy Exchange Between Balanced Motions and Near‐Inertial Internal Waves in the Northeastern South China Sea

Zongwei Feng, Mingfang Miao, Zhiwei Zhang, Jinchao Zhang et autres

Abstract The energy exchange between balanced motions and near‐inertial internal waves (NIWs) serves as a key pathway for cross‐scale energy redistribution; however, its characteristics remain poorly understood. Based on a submesoscale‐permitting simulation, the kinetic energy exchange rates (KER) between balanced motions (consisting …

First High‐Resolution Observations of Coexisting Dissipative Oscillations and Kelvin–Helmholtz Billows in Internal Solitary Waves

Hongli Liu, Xiaodong Huang, Xiaojiang Zhang, Siwei Huang et autres

Abstract Shoaling internal solitary waves (ISWs) can rapidly transfer substantial energy to turbulence, yet the small‐scale processes governing this transition are rarely observed directly. This study presents high‐resolution shipboard‐mooring measurements on the continental slope of the South China Sea. Numerous oscillations were …

Transition of Turbulence Features From Frontal Modulation to Typhoon Forcing Over the Northern South China Sea Shelf

Jianing Li, Qingxuan Yang, Hui Mei Sun, Yanwei Zhang et autres

Abstract Ocean turbulence, crucial for regulating Earth systems, is substantially modulated by background dynamic processes. Using 8‐day‐long hourly microstructure observations over the South China Sea shelf in summer, we investigate turbulence evolution under strong stratification and successively modulated by a front and …

Three‐Dimensional Evolution of Internal Solitary Waves in the Northern South China Sea Revealed by SWOT Observations

Tongxin Wang, Xiaodong Huang, Yunchao Yang, Siwei Huang et autres

Abstract Utilizing 250‐m resolution sea surface height anomaly (SSHA) data from the Surface Water and Ocean Topography (SWOT) satellite in combination with mooring measurements, this research investigates the three‐dimensional evolution of internal solitary waves (ISWs) in the northern South China Sea (nSCS). …

Variability of turbulent mixing observed by high-resolution Acoustic Doppler Current Profilers in the deep South China Sea

Chun Yan Zhou, Xin Xiao, Shoude Guan, Xiaodong Huang et autres

Despite its crucial role in sustaining the global meridional overturning circulation, turbulent mixing remains poorly observed, particularly in the deep ocean. We deployed 1200 kHz Acoustic Doppler Current Profilers (ADCPs) with high temporal [O(1 s)] and spatial [O(2 cm)] resolution to obtain …

Spatiotemporal Variations and Parameterization Scaling of Submesoscale Eddy Diffusivity in the Global Ocean

Qingguo Yuan, Zhiwei Zhang, Bo Qiu, Wei Zhao

Abstract Submesoscale eddies are important horizontal transporters of oceanic heat, salt, and other tracers, and their transporting efficiency is described using an eddy diffusivity in analogy with molecular diffusion. Although submesoscale eddies have been widely studied, global submesoscale eddy diffusivity ( K …

Observation of Internal Tides in the Andaman Sea: Energetics, Spatiotemporal Variability and Modulation by Equatorial Kelvin Waves

Yunchao Yang, Xiaodong Huang, Wei Zhao, Jingsong Guo et autres

Abstract The Andaman Sea, a global hotspot for multi‐source internal tide generation, exhibits complex tidal dynamics that remain poorly understood. Combining 22‐month mooring measurements with satellite data, this study comprehensively investigates the energetics, spatiotemporal variability, and equatorial Kelvin wave modulation of the …
