Xiaoying Zhou · Qingdao Haiyang Daxue xuebao · 2005
By power spectrum analysis, Mann-Kendall abrupt change test and correlation analysis, we reveal the seasonal and interannual SST variations in the Changjiang estuary and find the characteristics of the SST variations. The results show that the highest SST appears in August and the lowest SST in February every year.There are SST oscillations in the Changjiang estuary with periods of quasi-2 and 3-5 years. The Monsoon and Changjiang runoff affect the SST variations in the Changjiang estuary. The abrupt change in SST in the Changjiang estuary took place in the year of 1989.
