Review on seasonal and interannual variation characteristics of low temperature center in the Yellow Sea cold water mass
Yellow Sea cold water mass is a prominent and significant marine phenomenon in the shallow sea of China's continental shelf,playing a crucial role in deep-sea fisheries and aquaculture.Low temperature is the main characteristic of Yellow Sea cold water mass.The change of the spatial variations and the properties of temperature and salinity of the low-temperature center are great importance for further understanding the marine environmental variability in this region.Based on the historical observation data and research findings,this paper provides a comprehensive review of the seasonal variation characteristics;with a particular focus on the interannual variation of the low-temperature center in the Yellow Sea cold water mass.The main characteristics of the interannual variation are as follows:the low-temperature center in the northern Yellow Sea exhibits a relatively small range of variation,with a slight northward shift overall;the two low-temperature centers in the southern Yellow Sea show large variations,with the western center shifting westward and the eastern center shifting southward;the temperature of the low-temperature center in the northern Yellow Sea and the western parts of southern Yellow Sea has been increasing,while the temperature of the eastern low-temperature center has been decreasing;the salinity of the northern Yellow Sea cold water mass has shown a slight decreasing trend,while the salinity of the southern Yellow Sea cold water mass shows a significant decreasing trend is observed.Finally,by addressing the existing controversies and limitations in current research,the necessity of further investigating the variation characteristics of the low-temperature center is emphasized,leading to the future prospect for the Yellow Sea cold water mass research.This paper provides a reference for the systematic study of the variation law of the Yellow Sea cold water mass,gaining the in-depth understanding and prediction of the marine environment change in the cold water mass region.
