A simple improvement to objective analysis of hydrographic data is proposed to eliminate spatial aliasing effects in tidally energetic regions. The proposed method consists of the evaluation of anomalies from observations with respect to circulation model fields. The procedure is run iteratively to achieve convergence. The method is applied in the Bay of Fundy and compared with traditional objective analysis procedures and dynamically adjusted climatological fields. The hydrographic skill (difference between observed and model temperature and salinity) of the dynamically adjusted objective analysis is significantly improved by reducing bias and correcting the vertical structure. Representation of the observed velocities is also improved. The resulting flow is consistent with the known circulation in the Bay.
本文提出了一种对水文数据客观分析的简单改进方法，以消除潮汐活跃区域的空间混叠效应。该方法包括评估观测值相对于环流模型场的异常情况。该过程通过迭代运行以实现收敛。该方法应用于芬迪湾，并与传统的客观分析程序和动态调整的气候学场进行了比较。通过减少偏差和校正垂直结构，动态调整后的客观分析的水文技能（观测温度和盐度与模型温度和盐度之间的差异）得到了显著提高。观测流速的表示也得到了改善。由此产生的水流与芬迪湾已知的环流一致。
