| Abstract: |
| Observations show that during summer especially in August, the northward expansion of the Changjiang(Yangtze) River diluted water (CRDW) is blocked in the vicinity of the Changjiang Estuary. To explain this phenomenon, Princeton ocean model (POM) is applied to simulate the summertime expansion pattern of CRDW. Numerical experiments show that to the north of the Changjiang Estuary, a tide-induced temperature front of a cold water centered at (34°N,122.5°E) plays the key role in determining the expansion pattern of CRDW. This front splits the CRDW into two parts:the main part expands northeastward, and the other small part expands northwestward off the coast of Jiangsu Province, China. |
