“…From Figure 2, one can find that the Kuroshio intrudes into the SCS in winter while it retreats eastward in summer. This resembles results in previous studies [e.g., Li and Wu, 1989;Gan et al, 2006;Yuan et al, 2006;Liang et al, 2008] (see reviews by Liu et al [2008]). …”

[1] The eddy energy sources and sinks in the South China Sea (SCS) are studied based on a high-resolution ocean circulation model. Eddies are found to acquire their energy from barotropic instability (BT), the release of available potential energy (APE) associated with baroclinic instability (BC) and horizontal convergence from surrounding areas, while they lose energy due to turbulent processes. Both the eddy energy sources and sinks show western intensification with their maximum around the southwestern SCS where most of the wind-input energy occurs, and the Luzon Strait where the Kuroshio intrudes the SCS in winter. Unlike that in the open ocean, the eddy energy in the inner SCS is confined to the upper layer. Besides, the eddy energy indicates clear seasonal variability, especially at the Luzon Strait where the eddy activity is much stronger in winter than in summer. Energy budget analysis suggests that APE releasing is found to be the most important eddy energy source, accounting for over 60% of the total, followed by energy convergence from surrounding areas in horizontal direction (around 20%) and energy released from BT (around 15%). Most of the generated energy is mainly balanced by the turbulent processes, while both of the downward energy flux and tendency term are negligible.

“…A83 and A80 have different time series of T-S characteristics (Fig.5b-e), indicating a sophisticated water exchange and circulation structure along the 121°E section that has been repeatedly described (Hu et al, 2000;Tian et al, 2006;Yuan et al, 2006;Liang et al, 2008;Liu et al, 2008;Chen et al, 2011b, c). One salty core higher than 34.8 is found on Profi le 3 from A83 at 200 m, and two highsalinity (>34.7) plaques were located on Profi les 1 and 2 from 160 to 230 m and on Profi le 4 above 150 m. The locations of the high-salinity regions on Profi le 3 from A83 and Profi le 4 from A80 are considered telling …”

“…The circulation pattern and multiple time scales variabilities of the Kuroshio intrusion in the SCS have been investigated in several major ways, such as from in-situ data (Chen and Huang, 1996;Chu and Li, 2000;Qu et al, 2000), satellite data (Centurioni et al, 2004;Ho et al, 2004) and modeling results (Qu et al, 2004). Observations indicate that Kuroshio intrusions into the SCS may have different appearances, and several potential forcing mechanisms control the intrusion events (Hu et al, 2000;Liu et al, 2008). Among these mechanisms, the Kuroshio loop current enclosed by both the infl ow and outfl ow of the Kuroshio through the Luzon Strait has often been quoted (Caruso et al, 2006) and reproduced in several numerical models (Farris and Wimbush, 1996;Xue et al, 2004).…”

“…1a). Driven by monsoonal wind, the surface circulation in the SCS presents a basin-scale, cyclonic pattern in winter and a double-gyre structure in summer (Wyrtki 1961;Fang et al 1998;Hu et al 2000;Liu et al 2008;Wang et al 2013). Subsequent studies indicated that the seasonal variability of the SCS circulation is subjected to the quasisteady Sverdrup balance, after a fast adjustment associated with the first-order baroclinic Rossby waves (Liu et al 2001;Wang et al 2003).…”

The interannual variability of the upper-ocean circulation forced by seasonally varying monsoonal wind is investigated in a two-layer quasigeostrophic (QG) model, with the aim to understand the low-frequency variability of the South China Sea (SCS) circulation. It is demonstrated that the seasonally varying monsoonal wind can force the upper-ocean circulation with significant internal variability, which is mainly associated with the intrinsic nonlinear dynamics of the summer double-gyre system. This arises from the fact that the intrinsic variability, characterized by the Rossby wave adjustment in the winter single-gyre system, is much weaker than that in the summer double-gyre system driven by the intergyre eddy potential vorticity flux through barotropic instability.
