RAINFALL VARIABILITY IN PORTUGAL AND SOME RELATIONS WITH THE OCEAN-ATMOSPHERE SYSTEM IN THE NORTH ATLANTIC - The scope of this study is to analyse rainfall variability in the Portuguese rainy season (Nov-Mar) during the 20th century, and examine some relations with the sea surface temperatures (SST) and geopotencial heights at 850 hPa (Z850) in the North Atlantic region. To build the Portuguese rainfall index (PRI), a principal component analysis (PCA) was performed on a matrix containing seven Portuguese stations with secular records (variables) and the years 1900 to 1993 (observations). This index is the first principal component (PC), which explains always over 60% of the total variance and all the seven stations used in the PCA have pos...
