Fig. 4: Changes in the tropical cyclone absolute and relative frequency against translation speeds.
From: Global warming changes tropical cyclone translation speed
a–h The range of the translation speed is 0–80 (km/h) with 10 (km/h) interval, and absolute (a, c, e, g) and relative (b, d, f, h) frequencies are globally averaged at each translation speed bin and at each latitudinal band from 0° to 10° (a, b), 10° to 20° (c, d), 20° to 30° (e, f), and 30° to 40° (g, h). Blue and cyan boxes are for the future climate and black boxes are for the current climate. Blue (cyan) means that the difference between the current and future climates is (not) statistically significant at a 99% level (p < 0.01, two-tailed Student’s t test).
