Upwelling off the west coast of Hainan Island in summer: Its detection and mechanisms

Abstract: The summertime upwelling off the west coast of Hainan Island is newly detected by satellite remote sensing sea surface temperature, and confirmed by both historical field observations and numerical modeling. Furthermore, numerical experiments are conducted to gain understanding of the upwelling mechanisms. A tidal mixing front (TMF) is identified as the vital factor triggering the formation of the upwelling. The baroclinic pressure gradient force, which stems from the intense density difference across the TMF,… Show more

“…In contrast, in summer, the winds reverse their directions and blow from the southwest, triggering offshore Ekman transport of surface water over the shelf [ Liu et al ., ; Gan et al ., ; Jing et al ., ; Wang et al ., ]. As a result, persistent surface cooling and thermal fronts were frequently observed from satellite Sea Surface Temperature (SST) during the summer upwelling seasons, particularly on the western shelf of the NSCS [e.g., Hu et al ., ; Lü et al ., ; Su and Pohlmann , ; Jing et al ., ].…”

“…Detected from satellite images, persistent surface cooling and thermal fronts stretch several hundreds of kilometers along the East Coast and West Coast of Hainan Island, accompanied by high chlorophyll concentrations [Wang et al, 2001;Hu et al, 2003;L€ u et al, 2008]. However, as one of the most important physical processes in the NWSCS, the upwelling and upwelling-induced thermal fronts (hereinafter abbreviated as upwelling and thermal fronts) have not been well understood so far.…”

“…As a result, from spring to summer, the sea surface temperature (SST) along the coast of the NSCS does not monotonically increase with solar radiation but dramatically declines after the onset of the southwesterly monsoon, and results in a persistent surface cooling throughout the summer upwelling season, particularly over the continental shelf of northwestern SCS (NWSCS) [Hu et al, 2003;L€ u et al, 2008;Su and Pohlmann, 2009;Jing et al, 2011].…”

“…However, the water volume transported to the shelf induced by upwelling events has not been estimated. Recently, there have been some studies on upwelling around Hainan Island (Lü et al 2008;Su and Pohlmann 2009). Nevertheless, the dynamics of the upwelling, such as upwelling structure, the influence of wind events, and response of estuarine water, is not yet fully understood.…”
