Extended Data Fig. 9: Distribution of drought sensitivity and the response lag in the hydrothermal space for different vegetation types.
From: Widespread spring phenology effects on drought recovery of Northern Hemisphere ecosystems
The hydrothermal space is characterized by the mean annual temperature (MAT, °C) and precipitation (MAP, mm) in the period of 1982–2015. Drought sensitivity was determined by the Pearson’s correlation coefficient between mean growing season NDVI and SPEI at timescale of 3 months. Drought response lag was measured by the duration (months) between the minimal SPEI3 anomalies and the deepest suppression of NDVI induced from drought events. Four different kinds of vegetation types were considered, including evergreen forests (Evergreen), deciduous forests (Deciduous), shrubs and grasses.
