Line Plot from Scientific Research

Time series of TC frequency (blue lines) and TC cluster frequency (orange lines) during 1979–2024 over the WNP. Kendall rank correlations (Tau) between TC frequency and TC cluster frequency are shown at the top left. The linear trends of TC frequency (T1) and TC cluster frequency (T2) are plotted as dotted lines, with the associated 10-year trend values presented in the top panel. Asterisks denote significance at the 95% confidence level on the basis of the 1,000-sample bootstrapping.
