Fig. 5
Impact of drought severity on correlations between DAPC1 and DRi over the Southeastern US states. Lead and lagged temporal correlation coefficients between DAPC1 and DAi of the Southeastern US states are shown in the y-axis with the total areal extents from abnormal dry through exceptional (D0–4), moderate through exceptional (D1–4), severe through exceptional (D2–4), extreme and exceptional (D3–4), and exception (D4) in the x-axis. Red and black solid circles depict the means and medians of the temporal correlations of DAPC1 and DRi over the Southeastern US states, respectively, from −3 months through +3 months. Blue cross, asterisk, and empty circles depict the temporal correlations of DAPC1 and DRi over the state of Florida, North Carolina, and the rest five states of the Southeastern US region
