From: Increasing peak intensity of tropical cyclones passing through the Korean Peninsula

Increase in peak intensity of tropical cyclones (TCs) passing through the Korean Peninsula (KP). (a)–(c), Timeseries of indicated TC metrics during June-October. All timeseries are filtered using the 1-3-4–3-1 technique. In c, the dashed lines and inset statistics indicate the mean values of peak TC intensity during Period 1 (1981–2002) and Period 2 (2003–2020), respectively. (d), (e), Composite map of peak TC intensity gridded into 2° × 2° horizontal resolution during Period 1 (1981–2002) and Period 2 (2003–2020), respectively. The black dots indicate six-hourly TC location. (f) Composite difference in peak TC intensity between Period 2 and Period 1, respectively. The dots indicate significance at p < 0.05. In (d)–(f), the black contour line indicates the 250 km buffer zone away from the KP. In d-f, the maps are plotted using ArcGIS 10.1 (https://www.esri.com).
