摘　　要：The South China Sea(SCS)is abundant with complex multiscale dynamic processes but their spatiotemporal variations,generation and evolution mechanisms,and mutual interactions remain inadequately understood due to the lack of long-term in situ observations.To explore oceanic multiscale dynamics in the SCS,the SCS Mooring Array(SCSMA)was began to be constructed since 2009.The SCSMA consists of∼40 moorings and is the largest in situ ocean observing system in marginal seas worldwide.The highest spatial resolution of SCSMA is∼1.5 km,and the longest duration of fixed-location observations reaches∼15 years.Long-term observations from the SCSMA have allowed significant advances in the understanding of large-scale circulation,mesoscale eddies,submesoscale processes,internal waves,turbulent mixing,and interactions and energy cascades of different processes.In particular,the full chain of forward energy cascade from large-scale currents to turbulence has been revealed.Different dynamic processes in the SCS constitute a three-dimensional multiscale circulation system which transports materials and tracers in a relay.Here,we first describe the SCSMA and its construction process,and then comprehensively review its relevant advances in multiscale dynamics.Prospects for the SCSMA and its future applications are given at the end.
