| Abstract: |
| Using Morlet wavelet transform and harmonic analysis the multiscale variability of subsurface temperature in the South China Sea is studied by analyzing one-year (from April 1998 to April 1999) ATLAS mooring data.By wavelet transform,annual and semi-annual cycle as well as intrasea-sonal variations are found,with different dominance,in subsurface temperature.For annual harmonic cycle,both the downward net surface heat flux and thermocline vertical movement partially control the subsurface temperature variability.For semi-annual cycle and intraseasonal variability,the subsurface temperature variability is mainly linked to the vertical displacement of thermocline. |
