　　基于海洋锋空间位置、水平分布结构和垂直扩展特征等时空特征参数，结合海洋锋空间结构几何模型，建立了区域海洋锋温盐三维结构快速重构特征模型，对黄海西部沿岸锋和东海黑潮中段锋锋区温度场进行了仿真计算，并与实测数据进行了比较分析，实验结果表明：仿真结果与实测数据符合较好，实验结果验证了特征模型的有效性和可推广性。海洋锋区声速具有明显的水平梯度变化，对声纳的水下探测和反探测产生显著影响，因此，需要建立实时估计获取锋区水下温、盐结构的方法。海洋锋特征模型能够快速有效地重构海洋锋区温度场，为实时获取海洋锋水下结构特征提供了方法。

Based on the spatial and temporal feature parameters of oceanic fronts including spatial position, vertical expansibility structure and horizontal distributions, combining with its spatial structure geometrical models, a few feature models for the regional fronts were set up. We applied these models in temperature analysis of the western Yellow Sea Front (WYF) and Kuroshio front in the Northeastern East China Sea and compare the data from the models with in-situ observations. The results showed that the simulation results well matched the actual meas-urement data, which suggests that these models were effective and applicable. Ocean fronts have an obvious hori-zontal gradient of sound velocity and have a significant impact on sonar underwater detection. Therefore, we need to establish a real-time estimation for the temperature and salinity structure of ocean front. The feature models pro-vide a real-time access to obtain the oceanic front underwater structure, which can be used to reconstruct the tem-perature structure real-time and effectively.
