Prediction from Weeks to Decades

Figure 3: As Fig. 2 but for Atlantic multi-decadal variability (AMV). All were were smoothed with a 9-year running mean. Positive AMV years are 1934-42, 1948, 1952-57, 1999-2005. Negative AMV years are 1906-22, 1971-78. Assuming 4 degrees of freedom, the contour values ±0.25 and ±0.5 are statistically significant at the 87% and 95% levels, respectively.
