Table 3 Correlation coefficients between residual chronologies and monthly standardized precipitation–evaporation index (SPEI) at different temporal scales for the period 1966–2015. Correlations were calculated from September of previous year to August of the current year. Values indicate maximum and minimum correlation indicating the month with highest signal (previous year in capital letters) and time lag in months (m)
