| 英文摘要 | Wind forcing and baroclinic processes are fundamental drivers of coastal circulation, yet their effects on particle transport from multiple river sources in semi-enclosed seas remain insufficiently quantified. This study investigated how wind forcing and baroclinic dynamics regulate riverine particle transport in the Bohai Sea using a Lagrangian particle-tracking approach. Results showed distinct variability in particle transport pathways among river sources and wind regimes. Under northeasterly winds, particles from the Yellow, Hai, and Luan Rivers were transported southward with relatively confined influence, whereas particles from the Liao River extended toward the Central Basin as wind strength increased. In contrast, under southwesterly winds, particles from the Luan and Hai Rivers exhibited extensive northward transport and the largest particle-influenced areas, while particles from the Liao River remained locally. Particle responses to increasing wind strength were non-linear and strongly modulated by coastal geometry. For example, moderate southwesterly winds (4 m/s) promoted offshore export of the particles from the Yellow River through Ekman transport, whereas stronger winds (7-10 m/s) generated alongshore currents and nearshore convergence that trapped particles within the Laizhou Bay. Neglecting density-driven processes resulted in more confined particle transport in the Bohai Sea, with particle-influenced areas reduced by up to 66% in barotropic simulations. These differences were associated with baroclinic modifications to surface circulation (up to similar to 0.2 m/s under the wind speed of 4 m/s) and changes in effective particle spreading, highlighting the critical role of temperature- and salinity-induced density-driven processes in shaping riverine particle transport pathways in semi-enclosed coastal systems. |
