| 摘 要： | 本文讨论了在低纬地区利用多时刻风的观测资料作资料同化的一些试验结果。在资料同化过程中,采用经验正交迭代法。有两种组成资料矩阵的方法。一是把风的两个分量分别作为两个资料矩阵的元素,另一个是把两个分量作为同一资料矩阵的元素。对这两种方法的试验和比较表明,后者比前者有更好的结果。资料同化所得到的风场,可用于客观分析。

| Abstract: | By using multiple-instant wind data, some experimental results of low latitudes data assimulation are discussed. The empirical orthogonal iteration method is used in data assimulation. Two methods in constructing data matrices are tested and compared.In the first method, the wind components are treated separetely in two different matrices. In the second method the wind components are treated as two elements in one matrix. Results show that the latter is better than the former. It is indicated that the obtained assimulation values are useful informations for objective analysis. |
