不同ENSO事件下海洋热量输送对南海叶绿素a浓度的影响
Effects of Ocean Heat Transport Under Different ENSO Events on Chlorophyll a Concentration in the South China Sea
摘要
Abstract
[Objective]This paper aims to investigate the regulatory mechanism of ocean heat transport on chlorophyll-a(Chl-a)mass concentration in the South China Sea(SCS),and provide a scientific basis for predicting marine ecosystem responses to El Niño-Southern Oscillation(ENSO)events,assessing fishery resources,and monitoring environmental conditions.[Method]Using Chl-a mass concentration,sea surface temperature(SST),heat content(OHC),and Niño3.4 data sets,statistical methods were employed to analyze the differential effects of ocean heat transport under different ENSO events on Chl-a mass concentration.[Results and Conclusions]From 1998 to 2024,Chl-a mass concentration in the SCS decreased from the coast to the deep sea.Chl-a mass concentration was negatively correlated with SST.During El Niño periods,the heat output from the northern boundary of the SCS increased,while the east boundary continuously input heat,resulting in the OHC in the northern,central,eastern,and southeastern areas of the SCS decreased.The heat output from the southwest decreased,causing an increase in OHC in the southwest.After a 6-month lag,SST increased overall,at a 3-months lag,the Chl-a mass concentration in the entire South China Sea basin significantly decreased,while the Chl-a mass concentration along the coast increased.During La Niña periods,the heat output from the northern boundary of the SCS decreased,while the east boundary continuously input heat,resulting in the OHC in the northern,central,eastern,and southeastern areas of the SCS increased.The heat output from the southwest increased,causing an decrease in OHC in the southwest.After a 6-month lag,SST decreased overall,at 3-month lag,the Chl-a mass concentration in the entire South China Sea basin significantly increased,while the Chl-a mass concentration along the coast decreased.关键词
