| 摘 要： | 根据常规最优插值算法,在引入时间关联的基础上,详细推导了动态最优插值法的具体同化表达形式,利用这些公式,可以处理常见的在海洋观测数据同化中存在的时间错位问题.在陆架海模式HAM-SOM基础上,以7月份的渤海海表温度为例,验证了同化公式的可行性,并得到了较好的同化结果.验证结果表明:该方案能够兼顾观测数据与背景数据双方的特性,同化后的结果更加接近实际情况.

| Abstract: | Developed a new scheme entitled "Dynamic Optimal Interpolation" for data assimilation on the basis of the traditional Optimal Interpolation method and then verified with SST data. The new scheme extends traditional optimal interpolation by taking time correlation into accounts, which is a key to assimilate the observed data measured at different time into the model. The result of twin experiment indicates that the new scheme can give attention to both the observations and the backgrounds, and that the results after assimilation are close to the observations. |
