It shows that the overall SST along the coast is higher in the southern part and lower in the northern part, and the discrepancy between south and north parts becomes smallest in winter and largest in summer. Along the southern coast of Zhejiang, SST as a whole generally has a uptrend at rising the rate of 0.017 ℃/ a in last 51 years. In addition, there are oscillation periods of 3.5 a, 5 - 6 a and 11 a stay with SST changes. Mainly, the annual cyclical variation determines SST with a good match of harmonic fitting effect.展开更多
