“…Ocean hydrodynamic conditions then determine the spatial distribution of nutrients in the sea mainly through current transport and turbulent diffusion. Consequently, the dispersion of the high volume of nutrients conforming to the YS oceanography results in a thriving marine ecosystem, which contributes greatly to the socioeconomic development of bordering coastal countries, namely China, North Korea and South Korea (Z. H. Zhang et al., 2019).…”

Ocean chlorophyll‐a concentration is a reliable indicator of phytoplankton biomass that plays an important role in controlling the marine ecosystem. Here, we investigated the interannual variations in sea surface chlorophyll‐a concentration (SSC) in the Yellow Sea and underlying mechanisms with 22 yr (1998–2019) of satellite ocean color observations. Results indicated that SSC showed a positive trend (0.039 mg m−3 yr−1 on average) during 1998–2010 and a negative trend (−0.058 mg m−3 yr−1 on average) during 2011–2019. Similar SSC trends occurred in the four seasons. These trends had larger magnitudes in inshore waters than in offshore waters. SSC variations were primarily driven by rainfall and anthropogenic nutrient emissions with a possibly secondary contribution from sea surface temperature (SST). During 1998–2010, increased rainfall and anthropogenic nutrient emissions largely enhanced the terrestrial nutrient inputs into the Bohai Sea and Yellow Sea. Coincidentally, decreased SST might have led to a weakened stratification in summer, favoring upward turbulent diffusion of deeper waters rich in nutrients and chlorophyll‐a. These processes resulted in significant increases of surface nutrient concentrations and SSC. During 2011–2019, the opposite processes occurred to generate decreased SSC. The current study highlights the change of SSC trends in the Yellow Sea in the first two decades of the 21st century and physical processes at work, enriching our understanding of ocean chlorophyll‐a dynamics in the global shelf seas.

“…Numerous rivers flow from China and the Korean Peninsula into the seas, providing substantial freshwater and land‐sourced nutrients to support high primary production and fisheries (Qu & Kroeze, 2010; Shi & Wang, 2012). This makes the study area an important marine ecosystem, which contributes significantly to the socioeconomic development of coastal countries (Zhang et al., 2019). Generally, the BS has lower temperature and salinity levels but higher concentrations of nutrients, chlorophyll‐a and suspended matter than the YS year‐round (Bao et al., 2009; Shi & Wang, 2012).…”

Connecting the Bohai Sea (BS) and Yellow Sea (YS), the Bohai Strait is vital in controlling physical‐biogeochemical conditions in the East Asian marginal seas. In August 2019, Typhoon Lekima moved northward inland into eastern China and caused drastic water exchange through the Bohai Strait. The specific variation and underlying dynamics involved were investigated with observations and high‐resolution numerical simulations. Volume transport featured an intense inflow followed by an intense outflow, with a fluctuation magnitude of 1.88 Sv, which was much greater than the seasonal‐interannual variations. The corresponding current patterns presented three phases: strait‐wide inflow, strait‐wide outflow, and outflow in the south and inflow in the north. The strait‐wide inflow was driven by strong east‐northeasterly winds through local Ekman dynamics. The strait‐wide outflow resulted from the dynamic adjustment of ocean currents accompanying the rapid weakening of easterly winds. The third current pattern was part of a large‐scale cyclonic circulation in the BS and North YS and was governed by different factors in the southern and northern straits. Further comparisons indicated that transport caused by winter storms and other typhoons in the year had opposite phase variations to that caused by Lekima. The underlying dynamics mainly involved local Ekman dynamics and/or remote wind forcing via the propagation of coastal trapped waves but could differ greatly from events. Finally, we found that to a large extent, geostrophic transport derived from the sea surface height difference across the Bohai Strait could be used as actual transport during synoptic weather events.

“…In particular, coastal oceans were hot regions with significant temperature variations in the bottom layer, which could be much stronger than those in the surface layer and differ from regions. Note that the YS has one of the most important large marine ecosystems in the world, and its coastal oceans are also one of the most densely maricultured areas in the world (Zhai et al., 2020; Zhang et al., 2019). Dramatic temperature variations could cause mass mortality of benthic creatures, leading to vast ecological and economic losses (Gao et al., 2017; Jiang et al., 2016; Zhai et al., 2020).…”

“…Surrounding the YSCWM below the mixed layer, there may be a weak cyclonic circulation due to the combined effects of tides and monsoon winds (Liu et al., 2021; Moon et al., 2009; Shi et al., 2016; Xia et al., 2006; Xu et al., 2002). The complicated hydrodynamic conditions and human activities together make the YS one of the most important large marine ecosystems in the world, contributing significantly to the socioeconomic development of coastal countries (Zhang et al., 2019).…”

Three‐Dimensional Temperature Responses to Northward‐Moving Typhoons in the Shallow Stratified Yellow Sea in Summer

Typhoons are the most severe synoptic events on Earth. They can cause intense vertical mixing and anomalous three-dimensional circulations in the ocean, both of which result in dramatic variations in water temperature (Liu et al., 2022). In the open ocean, the intense vertical mixing generated by typhoons' strong winds leads to significant sea surface cooling and subsurface warming, which are usually biased to the right/left side of the typhoon tracks in the Northern/Southern Hemisphere (
