Abstract By analyzing 22 years (1993–2015) of daily eddy data, statistics surface properties were refreshed in the South China Sea. More than 7,000 historical Argo profiles collocated into eddy‐centered coordinates to reveal composite mean three‐dimensional structure eddies. The results indicate that eddies both polarities have long conical shape, with a maximum (minimum) density anomaly 0.55 kg/m 3 (−0.51 ) at 60 m (90 m) cyclonic (anticyclonic) eddy. Temperature and salinity anomalies also...
Abstract Global climate change and human activities have important effects on the water discharge sediment load of Pearl River. In this study, were investigated by using hydro-meteorological data from 1954 to 2018. The linear regression, Mann–Kendall abrupt test double mass curve employed detect trends change-points in quantify load. results revealed that annual exhibited a significant decreasing trend at rate − 2.24 × 10 4 t/year, regardless discharge, an occurred 1998. Human activities,...
Based on the in situ data and ADCP observation fall, it is found that a northeastward current at inter‐middle level flows Northern South China Sea (NSCS) continental shelf. This almost along isobaths, deflects from isobaths veering toward deep water when flowing over Dongsha Islands. Geographic currents derived climatologic hydrography (WOA01) absolute dynamic topography (ADT) confirm deflection of NSCS continent. A fine resolution regional ocean model which can well reproduce large scale...
Abstract The western South China Sea (WSCS) exhibits intense mesoscale eddy activity, especially in summer. However, the influence of eddies on regional ecosystems is not well understood. By analyzing historical situ observations, satellite‐derived near‐surface chlorophyll (CHL) data and data, we investigated composite response CHL to WSCS. results show that decrease WSCS nearly half this attributed activity anticyclonic during summer when they are much more energetic than cyclonic eddies. A...
Abstract Energetic fluctuations with periods of 9–14 days below a depth 1400 m were observed in the southern South China Sea (SCS) from 5 years direct measurements. We interpreted such as topographic Rossby waves (TRWs) because they obey dispersion relation. The TRWs persisted May 24, 2009 to August 23, 2013, and their bottom current speed maximum ~10 cm/s was one order magnitude greater than mean comparable tidal currents near bottom. bottom-trapped had an approximate trapping 325 reference...
The hydrodynamic performance of a floating cylindrical oscillating water column (OWC) wave energy converter is investigated experimentally and numerically. physical experiment carried out in flume at Dalian University Technology. OWC device constrained by springs only moves vertically. A second-order time-domain Higher-Order Boundary Element Method, based on the perturbation expansion technique, used to simulate nonlinear interaction with device. terms concerning pneumatic viscous damping...
Extreme ocean temperature events are becoming increasingly common due to global warming, causing catastrophic ecological and socioeconomic impacts
Internal tides profoundly influence diapycnal mixing and marine ecosystems in oceans worldwide. Previous estimates on internal focused regionally spanning a decade, leaving knowledge gap regarding their long-term global behavior, especially over centuries. Because of limited observations, critical question arises: How will warming affect tides? Using the Coupled Model Intercomparison Project Phase 6 (CMIP6) High-Resolution Empirical Tidal (HRET) model, we identify robust accelerating trend...
Abstract With the combined analysis of synthetic aperture radar image and satellite altimeter data collected in northeastern South China Sea (SCS), this study found one type distorted phenomenon internal solitary wave (ISW) with long front caused by oceanic mesoscale eddy. Motivated these observations, authors carried out numerical experiments using fully nonhydrostatic nonlinear MITgcm to investigate perturbation ISWs an isolated cyclonic or anticyclonic The results show that ISW is eddies...
Abstract Mooring data collected on the continental slope of South China Sea show that along‐slope deep sea bottom currents are generated when large spring internal tides (internal waves with tidal frequency) observed, maximum velocity amplitude exceeding 0.15 m/s. The observations consistent predictions near‐bottom breaking can result in generation flows these obliquely approach slope. A linear tide model one horizontal dimension realistic topography and stratification is used to likely due...
Abstract Oceanic barrier layer impedes the vertical exchanges of heat and biogeochemical substances between mixed deep ocean, playing essential roles in modulating air‐sea flux oceanic cycles. Recent studies revealed that mesoscale eddies can modify motions layer. But their influence on has not been determined. By analyzing more than a decade situ, satellite, reanalysis data, this study investigated Bay Bengal. The results show anticyclonic is significantly thickened winter (by 50% average)....
