Fig. 3From: Seasonal march patterns of the summer rainy season in the Philippines and their long-term variability since the late twentieth centurya–f Classification of patterns of the time coefficients of EOF1 using cluster analysis. The dotted red line and thick solid black line indicate the mean time coefficients averaged for 1951–2012 and for the years classified in each cluster (a C1, b C2, c C3, d C4, e C5 and f C6), respectively. The gray thin line indicates the time coefficients in each yearBack to article page
