Influence of the northern Yellow Sea Cold Water Mass on picoplankton distribution around the Zhangzi Island, northern Yellow Sea

Influence of the cold bottom water on taxonomic and functional composition and complexity of microbial communities in the southern Yellow Sea during the summer

“…Some research has surveyed the biological and chemical characteristics of the YSCWM, including the distribution patterns of bacterioplankton, phytoplankton, zooplankton, chlorophyll, primary productivity, nutrients (Li et al, 2006;Wang et al, 2011;Wei et al, 2016;Kang & Kim, 2008;Fu et al, 2016;Gao & Li, 2009;Tan & Shi, 2012). Studies on the microbial communities here have found that the phytoplankton biomass and productivity in the YSCWM were significantly lower than in its surrounding waters (Zhao et al, 2018;Li et al, 2006;Kang & Kim, 2008;Hur et al, 1999;Zhao et al, 2011), and the bacterial communities in the YSCWM contained a higher proportion of α-Proteobacteria (Wang et al, 2011). Marine microorganisms are known to play a critical role in the marine ecosystem functioning (Azam & Malfatti, 2007;Falkowski et al, 2008), and microbial biodiversity (e.g.…”

“…The cold water mass is a special hydrologic phenomenon in the Yellow Sea and has attracted wide attention (Weng et al, 1988;Guan, 1963;Wang et al, 2003;Zhao et al, 2018). Previous studies mostly focused on physical oceanographic features of the YSCWM, including its thermohaline structure and evolution mechanism (Weng et al, 1988;Guan, 1963;Su & Huang, 1995;Yu et al, 2006).…”

Climatic interactions between cold surges in the South China Sea and North Pacific extratropical cyclones

“…During these cold waves, a 'bomb cyclone' hit North America, resulting in the coldest Christmas in almost 40 years. Researchers have observed the presence of ECs in conjunction with cold surges in a few case studies (Kumar, 2021;Yao et al, 2023;Zhao & Zeng, 2005;Zhang et al, 1993b). Zhao and Zeng (2005) described a strong East Asian cold wave (surge) that crossed the equator in early January 2005.…”

“…A key question emerging from this event is whether the two explosive cyclones influenced and intensified the cold surge. Zhang et al (1993b) reported the case of an EC that underwent explosive development following a cold surge during 26-29 November 1982. Specifically, an EC that formed in the southern Yellow Sea on 28 November deepened rapidly to 972 hPa over the following 24 h, drawing in a large amount of cold air from the north.…”

“…By 3 December, a reverse Ω flow pattern was established over East Asia, followed by the breakout of a second cold surge during 4-8 December. Zhang et al (1993b) suggested that the occurrence of cold surges strengthens the jet stream, in turn fuelling the explosive development of cyclonic airflow. The development of intensive cyclones then fosters the subsequent breakout of cold air waves.…”
