Extended Data Fig. 9. Comparisons of drought severity and impact between overshoot and non-overshoot droughts.
a Differences in minimum de-seasonalized detrended NDVI between overshoot and non-overshoot drought events. c Differences in minimum 3-month SPEI anomalies between overshoot and non-overshoot drought events. b and d, similar as a and c, but for differences of integrated sum of NDVI and SPEI during drought. Overshoot droughts, compared to the non-overshoot ones, usually have weaker drought stress (bottom panel), but relatively stronger impact on vegetation (upper panel). Insets show the histogram of differences in anomalies.
