Multi-scale analysis of turbulence dissipation in the South China Sea

Measurements for long-term ocean turbulence observation are obtained from a mooring line deployed in the South China Sea. The measurements were made at a single level of 250m depth in the water column for about 3 month duty cycle. These time-extended measurements of TKE have yielded a valuable database. Based on advanced spectral methods for dissipation time series, the evolution processes of ocean turbulence in the South China Sea are illustrated. The distribution patterns of dissipation in different time-scales reveal the multiscale evolution and time dependence over tidal cycle. The extended observations of dissipation will contribute to improving our understanding of the ocean evolution processes of multiple time scales in the South China Sea.
