Under constant eddy viscosity coefficient conditions, the different parameter <em>β</em> (the ratio of the eddy viscosity term to the local acceleration term) predominantly governs the LRV by modulating the Lagrangian mean barotropic pressure gradient, while the Lagrangian mean eddy viscosity term exerts a negative feedback effect. Under varying eddy viscosity conditions, dominant components of total Lagrangian mean eddy viscosity term vary across turbulence closure schemes and the governing mechanisms of LRV become increasingly complex. The pioneering research meticulously tracks particle motion from the zero-velocity initial phase, establishing an equivalence between LRV and the two-time Lagrangian integrals of the acceleration and other dynamic terms. The two-time Lagrangian integrals of local acceleration and horizontal advection terms play the dominant roles in the LRV, while the vertical advection terms provide supplementary effects. Under non-stratified conditions, the two-time Lagrangian integrals of barotropic component generally counterbalance the two-time Lagrangian integrals of eddy viscosity component. In stratified contexts, upper-layer LRV in the along-estuary direction is influenced primarily by the two-time Lagrangian integrals of barotropic component, contributing up to half of the total LRV, while the lower-layer inflow is significantly shaped by the combined interaction of two-time Lagrangian integrals of eddy viscosity and baroclinic components. In the cross-estuary direction, unlike the along-estuary direction, the two-time Lagrangian integrals of eddy viscosity component contribute negatively to LRV.</div></div>","PeriodicalId":19457,"journal":{"name":"Ocean Modelling","volume":"195 ","pages":"Article 102528"},"PeriodicalIF":3.1,"publicationDate":"2025-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Three estimates of the transit time of the deep waters between Cabot Strait and the head of the Laurentian Channel, a deep channel cutting through the GSL, have been published up to now. Here, using lagrangian tracking experiments in a regional ocean model, we provide a new estimate of the transit time in the deep layer (&gt; 225 m) of the GSL, as well as the first estimate of the transit time in the intermediate layer (50–175 m). Our estimate for the deep layer is 3.2 ± 0.7 years. The transit time in the intermediate layer (1.2 ± 0.5 years) is nearly three times faster than in the deep layer. The deep waters travel mainly up the Laurentian Channel, whereas most of the intermediate waters first transit through the Esquiman and /or Anticosti Channels. Our results also highlighted the impact of the seasonal changes in large-scale circulation on the transit times of the particles seeded at Cabot Strait. In summer and fall, the circulation is relaxed, and subsurface waters transit slowly but more directly upstream, leading to faster transit times. In winter and spring, the circulation is intensified but many particles get caught in large gyres prevalent during these seasons, leading to slower average transit times.</div></div>","PeriodicalId":19457,"journal":{"name":"Ocean Modelling","volume":"195 ","pages":"Article 102526"},"PeriodicalIF":3.1,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549771","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, as most ocean general circulation models (OGCMs) do not resolve the scales of IWs and turbulence, to appropriately express the IW-induced turbulent dissipation is a long-lasting issue for ocean model development. Here we report the estimates of IW-induced turbulent dissipation in the South China Sea (SCS), from a tide-included OGCM using an internal wave continuum parameterization scheme (IWCP). The estimation is based on the energy level of internal wave continuum (IWC), by converting the finescale parameterization (FSP) from wavenumber to the frequency domain. The estimated dissipation rates are elevated over the Luzon Strait (LS), northern SCS, and continental slopes, up to <em>O</em>(10⁻⁷) Wkg⁻¹ between 100 and 500 m depth, while those in the central basin of SCS are <em>O</em>(10⁻¹⁰) Wkg⁻¹. The performance of IWCP are evaluated against observational datasets (Argo, CTD based FSP estimates, and CTD based Thorpe scale method estimates) and tidal-mixing parameterization schemes. The errors in IWCP's results are comparable with the discrepancies among different observational datasets. The IWCP significantly outperforms the widely used tidal mixing parameterization that only considers local internal tides, and are comparable, if not superior, to the tidal mixing parameterization that consider both local and non-local generation, depending on the choice of benchmark observational datasets. This work illustrates that IWCP could be an alternative efficient mean to estimate the three-dimensional map of IW-induced mixing from the high resolution OGCM.</div></div>","PeriodicalId":19457,"journal":{"name":"Ocean Modelling","volume":"195 ","pages":"Article 102525"},"PeriodicalIF":3.1,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143549773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assessments with satellite and Argo observations show that the model forced by Scatsat-I winds and reanalysis fluxes simulates the changes in the upper ocean reasonably well. The biophysical variability is significantly realized in a cyclone-induced open-ocean upwelling region underlying the peak intensity of the cyclone. After the passage of the cyclone, surface chlorophyll-a concentration increases tenfold in the upwelling region.

Results show the cooling of upper layer temperature during cyclone is due to vertical processes (entrainment and mixing), which is recovered in the post-cyclone period due to MLD advection affecting entrainment and vertical mixing, followed by restoration of net surface heat flux. The increase in salinity during the cyclone is due to MLD tendency dominating vertical entrainment process, and the post-cyclone recovery is due to the horizontal advection and net surface freshwater flux. The shoaling of the nutricline allows for the transport of the nutrients from the deeper layers to the euphotic zone and enhancement of phytoplankton concentration at the surface about five days after the cyclone interaction. Budget analysis for biological processes showed the changes in the phytoplankton concentration are associated with (i) nitrate uptake by phytoplankton and (ii) zooplankton grazing on phytoplankton.

To address this gap, this paper introduces an enhanced modeling approach that integrates both ice-induced wave attenuation and wave-induced ice breakage. To implement these processes, the Finite-Volume Community Ocean Model (FVCOM) is coupled with an unstructured-grid wave model (SWAN) and the unstructured-grid version of the Los Alamos Sea Ice Model (UG-CICE) to form the FVCOM–SWAVE–UG-CICE framework.

Results of the modeled ice concentration, ice thickness, and significant wave heights were reported and validated against observational data from the U.S. National Ice Center (NIC) and in-situ under-ice measurements. To further study the coupling effects, results of the proposed model were also compared with those from no coupling and one-way coupling (focusing only on ice-induced wave attenuation) models.

For this purpose, a 3D high-resolution coupled circulation-wave model based on unstructured grids is employed, which enables an effective transition in resolution from ∼2 km in marine open boundaries to ∼2 m near the foundations. The OWF monopiles induce different local and regional changes of the monthly mean velocity at mid-depth: a decrease of ∼5 % near the piles and an increase of ∼1 % in a wider region surrounding the OWF. The latter can be attributed to the relevant regional reduction in water density of ∼0.02 %. Consequently, the monthly potential energy anomaly increases by ∼5 % outside the OWF, while it decreases by 40 % inside it. The monopiles reduce the monthly significant wave height (Hs) from ∼5 % within the OWF to &lt;1 % over distances of ∼20 km. The prevailing westerly waves can affect the tidal asymmetry, particularly on the eastern side of the piles. This results in an asymmetry in the intensity of turbulent wakes on either side of the piles, in both monthly and tidal timescales. However, wave intensification can disrupt the periodic tidal pattern of the wake.
