Fig. 4: Drivers of flash drought occurrence.
From: Global distribution, trends, and drivers of flash drought occurrence
Percentage of flash drought events with an SPI anomaly (SPI ≤ −1), a PET anomaly (PET ≥ 1), an SPI and PET anomaly (SPI ≤ −1 and PET ≥ 1), and an SPI or PET anomaly (SPI ≤ −1 or PET ≥ 1) from the four reanalysis data sets (different colored bars) for each of the domains outlined in black on the map. The black dotted lines represent the mean between all four reanalysis data sets.
