SPATIAL AND TEMPORAL PATTERNS OF PRECIPITATION IN SPAIN FOR THE PERIOD 1880–1992
The longest series of precipitation records in Spain are analysed using the principal component analysis (PCA) method. EOF analysis was used to spatially summarise the rainfall data and to enable clarification of the role of the dominant circulation regimes affecting the region. Three significant EO...
