“…The Yellow Sea Cold Water Mass is a bottom pool of remnant Yellow Sea Winter Water 16 , which is most significant in summer 28 , 32 . The existence of the Yellow Sea Cold Water Mass causes a strong stratification in the centers of north Yellow Sea and south Yellow Sea 16 , 33 . The Yellow Sea Warm Current is the main component of the Yellow Sea circulation, which initiates in fall, becomes strongest in winter then weaker in spring and weakest in summer 34 .…”

The Yellow-Bohai Sea (YBS) is a typical marginal sea in the Northwest Pacific Ocean; however, little is known about the dynamics of particulate organic carbon (POC) and underlying mechanisms. Here, we analyze the spatial and temporal variations of surface POC derived from MODIS-Aqua during 2002–2016. Overall, POC is higher in the Bohai Sea (315–588 mg m−3) than in the Yellow Sea (181–492 mg m−3), and higher in the nearshore than in the offshore. Surface POC is highest in spring in the YBS, and lowest in winter (summer) in the Bohai Sea (the Yellow Sea). The spatial and seasonal patterns of POC are due to combined influences of primary productivity, water exchange, sediment resuspension and terrestrial inputs. Surface POC shows an overall decreasing trend prior to 2012 followed by an upward trend until 2015 in the YBS, which is almost opposite to chlorophyll; the decrease (increase) may result from strengthened (weakened) water exchange with the East China Sea through the Yellow Sea Warm Current. Declined terrestrial runoff is also partly responsible for the decrease prior to 2012. Our study suggests that water exchange and sediment resuspension are dominant factors regulating the spatial and temporal variability of POC in the YBS.

“…Therefore, a strong seasonal thermocline forms quickly and reaches its peak in the summer at a depth of 10–20 m. Since this strong stratification prevents vertical mixing, the cold water that formed during the previous winter is retained below the thermocline (Lee et al, ). This cold water is widely known as the Yellow Sea Cold Water Mass (YSCWM; Chu et al, , Chu et al, , Chu et al, ; Guan, ; He et al, ; Hu & Wang, ; Jiang et al, ; Kim & Kimura, ; Lee et al, ; Park et al, ; Su, ; Su & Huang, ; Yang et al, ; Yuan, ; Yuan & Li, ; Zhang et al, ) and persists throughout the entire summer, occupying almost 30% of the area of the YS. The YSCWM is also characterized by a sharp temperature difference between the sea surface and the bottom with a maximum depth less than 80 m (e.g., >15 °C; Lee et al, ).…”

A significant sea surface temperature (SST) drop was clearly identified to be confined exactly over the Yellow Sea Cold Water Mass (YSCWM) from satellite‐derived SSTs during Typhoon Muifa's passage over the Yellow Sea (YS) in early August 2011. With a simple one‐dimensional mixed‐layer model (Price‐Weller‐Pinkel [PWP]), the mixed‐layer heat budget diagnosis concluded that the entrainment term, rather than the surface heat flux term that usually dominates over the open ocean, was the dominant process for the significant SST cooling over the YSCWM. The PWP‐based experiments were conducted to set up one lookup table including the SST drop, wind speed, and subsurface temperature gradient, from which the YSCWM's intensity (represented by the subsurface temperature gradient) can be easily found with the satellite wind and SST measurements during the typhoon passage over the YS. This YSCWM‐anchored significant SST drop provides a promising possibility to detect the YSCWM intensity and extent, which have generally been poorly sampled to date.

“…Changes in the SYSCWM temperature are closely related to changes in atmospheric forcing during summer and winter, such as the Siberian High, the Aleutian Low, and sea surface temperature (SST) in the Kuroshio and the Alaska currents (Park et al 2011). An increase in the southern limit of the SYSCWM in summer was reported to occur after a decrease in the SST of the YS the previous winter (Yang et al 2014). Researchers found that the trend toward increasing SST in the YS was consistent with the climate warming in northern China and the adjacent seas (Lin et al 2005), and was related to the bathymetry and Arctic Oscillation signals (Park et al 2015).…”
