Extended Data Fig. 2: Changes in the mean translation speed of landfalling TCs 60 h before landfall and their trends.
From: Landfalling tropical cyclones accelerate due to land–sea thermal and roughness contrasts
Mean translation speed 60 h before landfall is shown for different periods: a 1950–1979 (pre-satellite era), b 1980–2021 (post-satellite era), and c 1950–2021. Seasonal variations: d spring, e summer, f autumn, g winter. Intensity categories: h TS, i Cat1, j Cat2, k Cat3, l Cat4, m Cat5. Dashed lines denote the linear trend, and shading indicates the two-sided 95% confidence intervals of the trend based on a Student’s t-test. The linear regression coefficients with their standard errors (m s⁻¹ per day), together with the corresponding R² and P values, are shown at the top center of each panel.
