This paper proposes an efficient clustering algorithm for Multivariate Time Series—PCA-CLUSTER.The algorithm applies principal component analysis to reduce the dimension of MTS,and subsequently chooses the principal component series of MTS to cluster by a K-nearest neighbor algorithm.

The EOF loadings corresponding to the five highest eigenvalues were used to delineate the air quality regions. The results of EOF method were difficult to interpret because they tend to cluster most stations into the first group. The results obtained by rotated EOF and cluster analysis are similar and more reasonable. It is interesting to note that the clustering results based on 1h and 8h data are similar. The principal component time series of EOF and REOF were analyzed to determine their temporal characteristics.

EOF和REOF法中均采用特徵值为最大的五个EOF负荷作为分区的依据，以EOF划分均质区后容易将大部份测站划为同一区而造成解释困难，而采用REOF方法和群集分析法所得结果相似且较为合理，利用最大小时与八小时臭氧浓度进行划分结果接近，本研究也针对EOF和REOF所求出的主成分时间序列加以分析，以了解其特性。
