“…The simulation captured well the predominant horizontal pattern of the remotely sensed SST (Figures 2a and 2b). The low temperature signal in the coastal region east of the PRE indicates intensified upwelling of deep water from the outer shelf, as presented in our earlier studies (N. Liu et al., 2020; N. Liu et al., 2020; Z. Q. Liu et al., 2020). Temporally, the interannual variability of the simulated SST was also highly consistent with the observations (Figure 2c).…”

“…These water intrusions convey the ENSO signal into the SCS through heat advection, especially in winter (Qu et al., 2004). With the aids of these atmospheric and oceanic forcings, SST (C. L. Liu et al., 2020; N. Liu et al., 2020; Z. Q. Liu et al., 2020) and the upper ocean heat content increase (decrease) (Q. Liu et al., 2011; Yan et al., 2010) during El Niño (La Niña) years, while surface water converges (diverges) and sea level increases (decreases) in the central basin of the SCS (W. D. Fang et al., 2014; Rong et al., 2007). The basin‐scale SCS circulation varies with the sea‐level changes and favors anomalous anticyclonic (AAC) (cyclonic) currents in El Niño (La Niña) years (G. H. Fang et al., 2006; W. D. Fang et al., 2006; C. Z. Wang et al., 2006; Y. G. Wang et al., 2006).…”

Using the numerical calculations of exposure time (), this study investigated the three‐dimensional characteristics of water exchanges associated with the coastal‐shelf circulations of the Northern South China Sea (NSCS). The circulation connectivity and its interannual variability under the modulation of El Niño Southern Oscillation (ENSO) were investigated. The gradually increased from approximately 50 days over the outer shelf to more than 150 days in the shallower coastal seas with the Beibu Gulf displaying a significantly longer (approximately 300 days). The Beibu Gulf played an influential role in the water exchange that had a contribution of over 30% to in the most regions. The results from sensitivity experiments indicate that the wind forcing is the primary controller of and the boundary flux plays a secondary role. Specifically, the wind enhances water exchange in western NSCS, particularly in the Beibu Gulf and Yuexi region. Conversely, boundary fluxes facilitate exchanges in the eastern shelf, such as Yuedong region. Analysis revealed a clear modulation from ENSO on water exchange, wherein El Niño and La Niña years displayed symmetrical morphologies in distribution anomalies, albeit with varying intensities. During El Niño years, the weakened southwestward shelf current increased and the shelf water was less likely to reach the Beibu Gulf, and once arrived, these waters were trapped inside to elongate . In contrast, during La Niña years, the strengthened southwestward shelf current shortened and more shelf waters were transported away from the NSCS by an intensified southwestward shelf current.
