Fig. 1: Flash drought occurrence and climate-vegetation regimes.

From: Global ecosystem responses to flash droughts are modulated by background climate and vegetation conditions

Fig. 1

a Flash drought frequency computed from ERA5 reanalysis soil moisture data (30 cm depth) over growing seasons between 2001 and 2020. b Climate-vegetation regimes defined by long-term dryness index and tree-cover dominance. Too arid or cold grid pixels are excluded. See Methods for more details. See also Fig. S2 for complementary analysis with SoMo.ml observation-based data30 and ERA5 deeper layer soil moisture data (60 cm depth). The map is created using the Matplotlib basemap v1.2.2 toolkit57.
