英文摘要	Based on mooring data in the Xisha area of the South China Sea from August 2007 to December 2016, we found that the diurnal internal tides (ITs) had a tendency to weaken from 2008 to 2016, while the semidiurnal ITs were enhanced from 2011 to 2015. The diurnal and semidiurnal ITs in the Xisha area were negatively and positively correlated with the Niño 3.4 Index, respectively. It was also found that the large-scale El Niño–Southern Oscillation (ENSO) can influence ITs. The link between ENSO and ITs is stratification. The upper-ocean stratification of the Xisha area in El Niño years was stronger than that in La Niña years. Under the effects of stratification, the structures of diurnal and semidiurnal ITs showed different patterns during El Niño and La Niña years; both were dominated by low modes in La Niña years but displayed more signals of high modes in El Niño years. © 2020.
