Extended Data Fig. 1: Changes in the mean translation speed of landfalling and non-landfalling tropical cyclones (TCs) and their trends.
From: Landfalling tropical cyclones accelerate due to land–sea thermal and roughness contrasts
Panels show mean translation speed of TCs in all ocean basins: a landfalling TCs, and b non-landfalling TCs at the same latitude ranges. Landfalling TCs cross the actual coastline, while non-landfalling TCs are from a random sample crossing an imaginary coastline 800 km offshore. 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) are shown at the top center, and the corresponding R² and P values are shown at the top of each panel.
