Fig. 3: Comparison of two clustered propagation patterns of contiguous heatwaves across China during 1961–2018.
From: Two different propagation patterns of spatiotemporally contiguous heatwaves in China
a Moving patterns of two types of contiguous heatwaves. The blue arrows in a indicate Type 1 while the red arrows indicate Type 2 and the tail (head) of each arrow indicates the centroid location of the first (second) half of the event. The rose diagram in the lower left corner in (a) shows the directional distribution of lifetime of the two types. b Comparisons in multiple metrics between two types. The statistics in the box plots in (b) from the upper to lower bound represent the value of Q3 + 1.5×(Q3–Q1), third quartile (Q3), mean (circle), median (horizontal line), first quartile (Q1), and Q1–1.5 × (Q3–Q1) successively. The value of Q3–Q1 denotes the interquartile range.
