Fig. 2: Humid-heat risk index (HHRI), vulnerability index (VI), hazard index (HI) and exposure index (EI) for urban and rural areas from 2001 to 2020.
From: Mitigating urban‒rural disparities in humid-heat risks in China
a HHRI; b VI; c HI; d EI. The solid red and blue lines represent the values of urban and rural areas, respectively, while the solid black lines represent the urban-rural difference (urban value minus rural value). The dashed red, blue, and black lines represent the linear fits for the values of urban, rural, and urban-rural difference, respectively. The red, blue, and black shadings around the dashed lines represent 95% confidence bands. Significance levels are indicated with *p < 0.1, **p < 0.05, and ***p < 0.01.
