Fig. 1: Timeseries of global rapid intensification (RI) activity in offshore regions.
From: Recent increases in tropical cyclone rapid intensification events in global offshore regions
a, c show the annual mean count of RI events within 400 km from the coast. b, d show the annual mean time fraction of RI for tropical cyclones within 400 km from the coast. RI is defined as an intensification of at least 45 kt/24 h for a, b and 30 kt/24 h for c, d. The blue lines and dots show historical data. The orange lines show linear trends, with shading denoting a 95% confidence interval.
