Extended Data Table 1 Trends in tropical-cyclone translation speed and their statistics

From: A global slowdown of tropical-cyclone translation speed

  1. The changes are shown as trends (km h−1 yr−1) and in percentage change over the period 1949–2016 in various regions and latitude belts. The regions include the North Atlantic, the western and eastern North Pacific and the northern Indian Ocean basins, and the Southern Hemisphere separated by 100° E. Other regions are separated by data over land and water, and by global latitude belts. Significance is shown by P values of the regressions and confidence intervals of the trends. Where identified by an asterisk, confidence intervals are based on effective degrees of freedom adjusted for serial correlation (see Methods). Significant trends, determined on the basis of the confidence interval, after correcting for serial correlation as needed, are shown in bold.
