Fig. 2: Changes in aridity terms and climate zones.
From: Divergent response of aridity index to historical land use and land cover change
Spatial pattern of multi-model mean (MMM) changes in aridity index (AI) (a), contributions by ∆P (b), and contributions by ∆PET (c). d MMM changes of original PET and fitted PET as a function of the background AI. e MMM values of contributions from ∆P and ∆PET as a function of background AI. f Area fraction changes in the four climate zones due to LULCC. g Spatial pattern of climate zone shifts. In (a-c), gray dots indicate that the changes and contributions are statistically significant at the p = 0.10 level, which are shown every 5 rows and columns for clarity. In (d) and (e), solid lines denote MMM values of the 11 models, and the shading denotes the 90% confidence interval (CI). In (f), bars denote MMM values and error bars denote the 90% CI. All percentage values in (f) are area fractions relative to the global land without Antarctica and Greenland. The area fractions of each climate zone with and without LULCC are also listed in (f) in the MMM value and 90% CI.
