通过对连云港海域(1976-2008)、吕泗海域(1960-1990)30年左右的海表温度(SST)资料进行随机动态分析;并计算了SST与Nio3.4指数、海表热通量和海面风场的相关系数。研究结果表明:从1976-2008年连云港的SST呈现长期升高的趋势,32年间约上升0.9℃;从1960-1990年吕泗的SST呈现下降的趋势,30年间共下降约0.22℃。月均的SST最大熵谱分析揭示了两站的SST具有12个月和6个月的显著变化周期,此外还有准2 a的振荡周期。东赤道太平洋海温的异常对连云港、吕泗海域的SST有一定的影响,热通量是影响连云港海域SST变化的部分因素,仅通过海面热通量的变化无法解释连云港海域海表温度升高的现象,海洋动力过程对SST的贡献不能忽略。连云港、吕泗海域的SST变化与风场的变化显著相关。
Through the stochastic dynamic analysis of the SST data of Lianyungang sea area (1976-2008) and Lü Si sea area (1960-1990) for about 30 years, the SST and Nio3.4 indices, SST Correlation coefficient between quantity and sea surface wind field. The results show that from 1976 to 2008, the SST of Lianyungang shows a long-term upward trend, rising about 0.9 ℃ in 32 years. From 1960 to 1990, the SST of Luosi showed a downward trend, with a decrease of about 0.22 ℃ in 30 years. The monthly mean SST entropy analysis revealed significant periods of 12 months and 6 months for the SST at both stations with an additional 2-year period of oscillation. The SST anomalies in the eastern equatorial Pacific have certain impacts on the SST in Lianyungang and Lv Si sea areas. The heat flux is a factor that affects the SST in the Lianyungang sea area. The change of the sea surface heat flux can not explain the sea surface temperature rise in Lianyungang sea area The phenomenon that the contribution of marine dynamic process to SST can not be neglected. The changes of SST in Lianyungang and Lvsi waters are significantly related to the changes of wind farm.
