Fig. 2: Spatial distribution of differences in distance at the threshold of 30 mm/3 hours (DIST30) between the late period (2001-2020) and the early period (1980-1999).
From: Global expansion of tropical cyclone precipitation footprint

Bars show the percentages of increasing and decreasing areas in each ocean basin/region. The cross indicates the difference at the location passed the Mann-Whitney test on the regression model of time series at the 99% significance level. DIST30 is collected within 4° grid cells for clear visualization of spatial patterns.
