The Correlation between Phenology and the Simulated Increase in Precipitation A simple linear regression analysis showed that the beginning times of leaf budding, leaf unfolding and leaf senescence had a marginally significant linear negative correlation with the increase in simulated precipitation during an extremely wet year (0.05 < p ≤ 0.10), but this correlation was not significant during an extremely dry year ( Figure 6 A).
