We investigated mean properties and the spatiotemporal variability of eddies in South China Sea (SCS) by analyzing more than 7000 corresponding to 827 eddy tracks, identified using winding angle method 17 years satellite altimetry data. Eddies are mainly generated a northeast-southwest direction southwest Luzon Strait. There is no significant difference between numbers two types (anticyclonic cyclonic) most regions. The radius lifetime 132 km 8.8 weeks, respectively, both depending on where...
This study describes characteristics of eddy (turbulent) heat and salt transports, in the basin‐scale circulation as well embedded mesoscale found South China Sea (SCS). We first showed features turbulent transports eddies using sea level anomaly (SLA) data, situ hydrographic 375 Argo profiles. that were horizontally variable due to asymmetric distributions temperature salinity anomalies they vertically correlated with thermocline halocline depths eddies. An existing barrier layer caused...
Abstract Structure and variability of internal tides (IT) near‐inertial waves (NIW) on the continental slope northwestern South China Sea were investigated, based 9‐month moored current observations from autumn to early summer in 2008 2009. The diurnal IT kinetic energy, dominant over that semidiurnal tides, is found exhibit apparent seasonal variability—strongest weakest winter—whereas variance remained nearly uniform throughout observation period. Moreover, more coherent (i.e.,...
Abstract Tropical Cyclones (TCs) are devastating natural disasters. Analyzing four decades of global TC data, here we find that among all TC-active basins, the South China Sea (SCS) stands out as particularly difficult ocean for TCs to intensify, despite favorable atmosphere and conditions. Over SCS, intensification rate its probability a rapid (intensification by ≥ 15.4 m s −1 day ) only 1/2 1/3, respectively, those rest world ocean. Originating from complex interplays between astronomic...
Based on moored observations and remote sensing data in July August 2005, energy sources for enhancing turbulent mixing possible mechanisms of phytoplankton bloom the continental shelf southeast Hainan Island under influence Washi, a fast-moving weak tropical storm, are analyzed this paper. Observations show that strong near-inertial internal waves were generated by rapidly changing wind stress was dissipated quickly across thermocline. The associated with baroclinic shear instability...
Abstract Based on observed temperature and velocity in 2005 northwestern South China Sea, the shallow ocean responses to three tropical cyclones were examined. The oceanic response Washi was similar common observations with 2°C cooling of surface slight warming thermocline resulted from vertical entrainment. Moreover, wavefield dominated by first mode near‐inertial oscillations, which red‐shifted trapped negative background vorticity leading an e ‐folding timescale 12 days. repeated...
A mooring system and two sites of bottom currents were deployed over the slope near shelf break on propagating paths internal solitary waves (ISWs), west off Dongsha Atoll in northern South China Sea. Data indicated that energetic ISWs obliquely shoaled onto an approximately 290° direction, causing strong reversing (some exceeding 80 cm/s) bottom. Two types sandwaves short scour channels are discernible seafloor break, which have reasonable correlations with incident tides. Type 1 sandwaves,...
Abstract Buoy-based observations of surface waves during three typhoons in the South China Sea were used to obtain wave characteristics. With local wind speeds kept below 35 m s −1 , over an area with a radius 5 times that which maximum sustained was found mainly dominated by wind-wave components, and energy distribution consistent fetch-limited waves. Swells at front outside central typhoon region. Next, dynamics studied numerically using state-of-the-art third-generation model. Wind...
Abstract Abundant mesoscale eddies propagate to the east of Taiwan and affect Kuroshio Current its onshore intrusion northeast Taiwan. But dynamical process how eddy activities modulate is still unclear. In this study, in situ ocean velocity observations, drifter trajectories, tide gauge measurements, satellite sea surface height data, assimilative Hybrid Coordinate Ocean Model (HYCOM) reanalysis outputs were used analyze a cyclonic eddy‐induced large during late autumn 2008. Along with nine...
Abstract Long‐range radiation and interference of M 2 internal tides from multiple sources in the Philippine Sea are examined by driving a high‐resolution numerical model. The effectively generated around boundary area, which includes Luzon Strait, Ryukyu Island chain, Bonin Ridge, Mariana Arc, Izu favoring occurrence complex patterns. local (mainly Daito Islands Palau Ridge) inside basin contribute to small portion (~5%) total energy but enhance geographical inhomogeneity baroclinic field....
Abstract Tropical cyclones may augment nutrients in the ocean surface layer through mixing, entrainment, and upwelling, triggering phytoplankton blooms oligotrophic waters such as South China Sea (SCS). Previous studies focused mainly on responses of marine environments to strong or slow‐moving typhoons SCS. In this study, we analyze variations chlorophyll a (Chl ) oceanic conditions continental shelf region east Hainan Island during fast‐moving tropical storm Washi investigate its...
Abstract The variability and energetics of M 2 internal tides during their generation propagation through the Kuroshio flows northeast Taiwan are investigated using a high‐resolution numerical model. corrugated continental slopes, particularly I‐Lan Ridge Mien‐Hua Canyon, first identified as energetic sources tides. domain‐integrated barotropic‐to‐baroclinic conversion rate under influence is ~2.35 GW, ~0.9 GW which generated at Ridge, ~0.93 ~0.52 north shelf. tide influenced by horizontally...
