| Abstract: | The mechanisms of establishment and adjustment of the basin-scale circulation in the South China Sea (SCS) during the monsoon-forced spin-up are investigated using a high resolu-tion circulation model in this paper. The process, in which the upper layer in the SCS evolved from the motionless state to the one when the basin-scale circulation initially established, was described, and the participation of various Kelvin and Rossby waves and their traveling time scales in differ-ent stages was revealed. It shows that the coastal trapped Kelvin waves and the westward propa-gating Rossby waves play important roles in the adjustment of the basin-scale circulation. Fur-thermore, the characteristic timescale of establishment for the basin-scale circulation in the upper layer of the SCS was obtained. |
