| Zusammenfassung |
In this work, cluster and principal component analysis are used to divide
Spain in a limited number of climatically homogeneous zones, based on
seasonal rainfall for 32 Spanish localities for the period 1912–2000. Using
the hierarchical technique of clustering Ward's method, three clusters have
been obtained in winter and spring, and four clusters have been obtained in
summer and autumn. Results are similar to those obtained by applying
principal component analysis. Centroid series of each cluster and principal
component series of each EOF have been compared to analyze the temporal
patterns. The comparison of both methods indicates that cluster analysis is
suitable to establish spatio-temporal patterns of seasonal rainfall
distribution in Spain.
