a Linear trend (m s-1 decade-1) of TC intensity, in which dots are statistically significant (at the 0.05 level) and the dashed box indicates the monsoon trough (MT) area. b Medians (m s-1; solid lines), interquartile ranges (bar), and linear trends (dashed lines) for TC intensity from the Joint Typhoon Warning Center (JTWC), Japan Meteorological Administration (JMA), and China Meteorological Administration (CMA) datasets in the MT area. c The TC intensity anomaly (m s−1; bar) and its linear trend (black long dashed line), the Pettitt’s test curve (black solid line) which is used to identify the change point of the TC intensity time series, and the p = 0.05 level (short dashed line). d Relationship between TC frequency and intensity in the MT area in P1 (period 1988–2001; blue) and P2 (period 2002–2018; red). All data are for July, August, and September only. This figure was created using R version 4.3.2 (https://www.r-project.org/). Source data are provided as a Source Data file.
