Abstract A self-organizing map (SOM) neural network was developed from Argo gridded datasets in order to estimate a subsurface temperature anomaly (STA) remote sensing data. The SOM maps were trained using anomalies of sea surface (SST), height (SSH), and salinity (SSS) data monthly datasets, labeled with STA 2005 through 2010, which then used the STAs at different depths North Atlantic estimated time series compared including independent for validation. In Gulf Stream path areas,...
This study quantitatively investigates monsoon-driven bedload sediment transport mechanisms in the Qiongzhou Strait using SCHISM model, revealing three key findings: (1) Monsoon seasonality governs net flux through contrasting hydrodynamic regimes, with winter monsoon establishing spatially coherent westward pathways, while summer induces counteracting flow patterns that suppress transport. (2) Winter conditions exhibit opposing vectors between tidal and forcing at both strait entrances,...
Abstract During the summer following El Niño, a basin-wide sea surface temperature (SST) warming takes place over tropical Indian Ocean (TIO), exerting profound influences on Asian monsoon. This is an important source of seasonal predictability for Based observations, however, present study finds that relationship between Niño-Southern Oscillation (ENSO) and TIO SST anomalies during decaying asymmetric with much weaker La Niña relative to Niño. The analyses show this can be explained by...
Abstract Ocean heat content (OHC) evolutions calculated from the data sets (WOA, MyOcean, ORAS4, and SODA) were examined at different depth ranges in this study. According to OHC changes, subsurface deeper ocean (SDO, 300–2000 m) rapidly increased over world's basins during 1998–2013, indicating significant warming SDO recent global surface hiatus. Almost all warmed up, but with various contributions tied The role of Indian is particularly important as it has accounted for about 30% uptake...
Two sets of more than 850 days mooring records and satellite altimeter data are used to explore the features spatiotemporal evolution near-inertial waves (NIWs) near Nansha Island in southern South China Sea (SCS). The observed NIWs dominated by clockwise (downward energy propagation) motions show a clear blue shift with distinct peak frequency 1.09 f during two large NIW events. kinetic (NIKE) is primarily concentrated upper layer radiated downward. largest value depth-integrated NIKE...
Abstract We investigate impact of an island on hysteresis a western boundary current (WBC) flowing across gap using nonlinear 1.5-layer ocean model. The results curves show the in middle facilitates WBC intrusion. inserted (removed) promotes to shed eddy (leap gap) when path transits from periodic penetrating (leaping) leaping (periodic penetrating) regime without (with) island. Vorticity balance analysis reveals that transition eddy-shedding (eddy-shedding) is induced by increased...
The seasonal warming over the southwestern Yellow Sea (YS) in spring is of vital importance to local ecologic environment, especially massive green algae blooms YS late and early summer. Based on daily optimum interpolation sea surface temperature (SST) data consisting satellite derived SST from Advanced Very High Resolution Radiometer (AVHRR) situ measurements, this study analyzed variation (SWYS) 1982 2018. results show that recent trend SWYS four-to-six times global average, as a result,...
To analyze the dependence of intensification rates tropical cyclones (TCs) on variation environmental conditions, an index is proposed here to measure lifetime maximum (LMIRs) for Saffir–Simpson scale category 4–5 TCs over western North Pacific. quantitatively describe rate major TCs, LMIR defined as acceleration in sustained-wind-speed a 24-h period overwater TC. This new index, LMIR, generally independent indices RI frequency. The results show that Pacific Decadal Oscillation (PDO)...
Marine sediment deposits near the Qiongzhou Strait have great potential as sources for beach nourishment and infrastructure industry aggregates. Estimation of bedload transport during spring tide improves understanding movement characteristic under dynamic conditions, which would further favor assessment mining marine sand resources. To study at eastern entrance Strait, surficial distributions were obtained through hundreds samples from field work. A semi-implicit cross-scale hydrological...
Abstract The influence of a large-scale circulation (LSC) in marginal sea on hysteresis western boundary current (WBC) flowing across gap is studied using nonlinear 1.5-layer ocean model. Results show that both single-gyre LSC and double-gyre are able to induce the critical-state WBC transition from eddy-shedding regime leaping regime, while only regime. dynamics suggests meridional advection enhanced by perturbation responsible for shift penetration leap reduced penetration. We also present...
The hysteresis of a western boundary current (WBC) flowing across gap and the dynamics mesoscale eddy–WBC interaction with presence two islands in are studied using 1.5-layer ocean model. WBC suggests that facilitate to intrude into basin by shedding eddies compared no-island case, but they promote leap one-island case. from east can induce critical-state shifting penetration vice versa. revealed vorticity balance analysis shows increased (decreased) meridional advection perturbed eddy...
Abstract We study a hysteresis western boundary current (WBC) flowing across gap impinged by mesoscale eddy, with an island of variable meridional size in the gap, using 1.5-layer ocean model. The curves suggest larger facilitates WBC intrusion shedding eddy more easily. Both anticyclonic and cyclonic eddies are able to induce critical transition from penetration regime leap regime, vice versa. vorticity balance analysis indicates increased (decreased) advection that induces shifting...
Abstract The influence of meridional shift the oceanic subtropical front (STF) on Agulhas Current (AC) regime shifts is studied using satellite altimeter data and a 1.5-layer ocean model. observations suggest northward STF leads to AC leaping across gap with little leakage, southward mainly results in intruding into Atlantic Ocean forms loop current an eddy-shedding path, while there are three flow patterns for moderate latitude STF. model no hysteresis (associated multiple equilibrium...
