通过统计相关分析检验验证了一个简单的温度参数模型在太平洋海域的较好适用性。进而基于Argo观测资料及WOA09气候态温度数据,采用最大角度法求得此模型的相关参数,并利用高分辨率的卫星遥感海表温度反演了太平洋上层海域空间分辨率为11 的气候态月平均三维温度场。通过与实测资料的比较分析,表明反演结果是较为真实可靠的,可作为海洋数值模式积分的初猜场,并为实现现场观测(如:Argo)与卫星观测的优势互补,构建太平洋海域完整的三维温度分析场提供一种新途径。 |

Abstract: |
A simple vertical thermal structure is proved to be applicable to the Pacific Ocean through correlation analysis test. Based on the Argo observations and WOA09 climate data, we determine the parameters with the maximum angle method. Then in the Pacific Ocean, a three-dimensional subsurface temperature field whose spatial resolution is 1 ° x 1 ° is inversed from high-resolution sea surface temperature. Compared with the observational temperature profiles, the inversion result is reliable and can be assimilated into the system of the ocean reanalysis as pseudo temperature observation. That will provide a strong theoretical basis and solid data base for realizing complementary advantages of the situ observation (such as Argo) and the satellite observation, which is conductive to construct the complete temperature analysis field. |
