Fig. 5: Population exposure to FWI with reduced Beaufort SIC.
From: Beaufort sea ice loss contributes to enhanced health exposure to fire weather over Southeast Asia
a The contribution of the decrease of the standard deviation in Beaufort SIC to FWI increasing percentage in Southeast Asia. b Population distribution in Southeast Asia. c Population-weighted FWI change percentage with 1 std SIC decrease. d Population exposure to FWI under different SIC reduction scenarios in Southeast Asia. The blue bar corresponds to the present scenario, the orange bar corresponds to a standard deviation reduction in Beaufort SIC, and the red bar corresponds to a double standard deviation reduction in Beaufort SIC. FWI values are divided into five categories: lower than 20 (low), 20–38 (moderate), 38–48 (high), 48–58 (very high), and higher than 58 (extreme)57.
