Fig. 3. Changes in the tropical cyclone translation speed, tropical cyclone absolute, and relative frequency against latitudes.
a–c The range of the latitude is 0–40° with 5° interval, and the speed and both frequencies are globally averaged at each latitudinal bin. Red (black) line (a) and boxes (b, c) is for the future (current) climate. The difference between the current and future climates is statistically significant at a 99% level (p < 0.01, two-tailed Student’s t test) at each bin for a–c.
