Moving window correlations calculated between mean site series of ring-width indices and monthly temperature (T.) and precipitation (P.) data from May to August. Moving correlations were obtained for 30-year intervals shifted by one year and the middle year of the interval is shown in x axes for each species (a, Pinus uncinata; b, Abies alba; c, Fagus sylvatica; d, Pinus sylvestris; e, Quercus robur; f, Quercus petraea). The colour scale (right side) shows the Pearson correlation coefficients
