一、方法的基本思想:一个多维时间序列,其列元素表示该多维时间序列的时间分布。其行元素可有两种情况:一种是行元素表示同一要素的空间分布;另一种情况其行元素表示某站某几个具有一定相关性的要素组成的行向量。如果我们把后一种情况的行向量和依赖于时间分布的列向量所 First, the basic idea of ​​the method: a multi-dimensional time series, the column elements that the multi-dimensional time series of time distribution. There are two kinds of line elements: one is the line element represents the spatial distribution of the same element; the other is the line element which represents the line vector composed of certain elements with certain relevance at a certain station. If we take the latter case of row vectors and time-dependent column vectors,
