The scientific objective of this study is to revisit the dominant physical processes that characterize tidal dynamics in the Gulf of Tonkin using a high-resolution model and combination of all available data. Particular attention is thus given to model-data cross-examination using tidal gauges and coastal satellite altimetry and to model calibration derived from a set of sensitivity experiments to model parameters. The tidal energy budget of the gulf (energy flux and dissipation) is then analyzed and its resonance properties are evaluated and compared with idealized models and observations. Then, the tidal residual flow in both Eulerian and Lagrangian frameworks is evaluated. Finally, the problem of tidal frontogenesis is addressed to explain the observed summer frontal structures in chlorophyll concentrations. specialized MER DE CHINE 032 91 37-56 2014 0278-4343 https://www.documentation.ird.fr/hor/fdi:010069886 10.1016/j.csr.2014.08.003 0278-4343 [F B010069886] https://www.documentation.ird.fr/hor/fdi:010069886 https://www.documentation.ird.fr/intranet/publi/depot/2017-07-05/010069886.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-07-05 2017-11-02 fdi:010069886 fre
