Moving correlation functions, relating tree-ring growth of European beech, precipitation (Prec) and maximum temperature (Tmax) from previous March to current October (PE-Pescofalcone, UG-Ugni, PG-Piana Grande, BK-Blockhaus). Moving correlation was carried out in windows of 35 years, offset by 5 years. Significant correlations are denoted by asterisks. Month of the current year is in capital letters, and that of the previous year is in small letters. The majority of coefficients (coef) display temporal fluctuations. Asterisks indicate windows with significant correlations, positive or negative, for the given variable
