a MJ mean SLP anomalies for four negative tree-ring cellulose events (A.D. 1954, 1956, 1966 and 1981). b MJ mean SLP anomalies for three positive tree-ring cellulose events (A.D. 1963, 1975, and 1987). Datasets were from NCEP/NCAR reanalysis 1 (Kalnay et al. 1996). These anomalies were normalized to zero mean and one standard deviation during A.D. 1948–2010
