Fig. 1: Trends in LAIMAM, VPDJJA and SMJJA during 1982-2020.
a Interannual standardized anomalies of the area-weighted average of LAIMAM (green dotted lines), VPDJJA (orange dotted lines) and SMJJA (blue dotted lines) for all northern region. The dashed lines indicate the least-squares linear regression for the variables corresponding to the colors. (b–d) denote the spatial distribution of LAIMAM, VPDJJA and SMJJA trends. The dotted area indicates that the trend is significant (P-value < 0.05). The white areas represent areas without vegetation cover that are masked off.
