摘要:
利用历史观测得到的温度剖面数据,通过严格筛选和插值,建立了南海北部的气候态垂向温度剖面。随后,利用回归统计分析的方法构建了海面温度异常(SSTA)、海面高度异常(SSHA)联合扩展温度剖面的经验回归模型,并采用卫星遥感得到的SST和SSH数据扩展了南海北部的三维海洋温度场,其时间分辨率为天,空间分辨率为0.25°×0.25°。通过与观测数据的对比研究,扩展得到的温度场可以较为准确地反映南海北部温度剖面的结构特征,并且能有效地体现出一些中尺度变化过程。结果表明,本研究反演得到的三维温度扩展场是较为可靠的,它可以作为海洋数值模型的初始场,实现现场观测数据和卫星遥感数据的互补,有助于更好地分析南海北部温度场的三维结构及变化特征。

Abstract:
On the basis of historically observed temperature profile data, a static climate temperature field was established through strict screening and interpolation. Then, regression analysis was used to build an empirical regression model to invert temperature profiles based on the sea surface temperature (SST) and sea surface height (SSH) anomalies. Finally, a three-dimensional temperature field was expanded in the northern part of the South China Sea using the remote satellite SST and SSH, whose temporal resolution is daily and spatial resolution is 0.25°×0.25°. Compared with the observational data, the expanded temperature field can accurately reflect the structure of the temperature profiles and can well describe some mesoscale variabilities in the northern part of the South China Sea. Results showed that the expanded temperature field is reliable and can be used as the initial field of the numerical model to determine the complementarity between observed and satellite data. Thus, a more in-depth analysis of the three-dimensional structure and variation characteristics of the temperature profiles in the northern part of the South China Sea can be conducted.
Key words:  northern part of the South China Sea  satellite sea surface temperature and height  inversion of the three-dimensional temperature field
