Climatological Features of Korea-Landfalling Tropical Cyclones

Figure 1

Decadal variation related to a Korea-landfall TC activity. Indices in order from an upper-most side are the total TC frequency (F-TDEC), the TC frequency with intensity greater than tropical storm (TS) (F-TSTY), Accumulated Cyclone Energy (ACE) of TC with intensity greater than TS, and total moving distance (TMD) for the TC lifetime, respectively. The periods of H5165, L6685, and H8604 indicate the first high frequency period for 1951–1965, the low frequency period for 1966–1985, and the second high frequency period for 1986–2004 defined by -value (thick blue line) of the statistical change-point analysis. The thick red, black dashed, and red dotted lines denote 5-year running mean, 54-year mean, and each period mean, respectively.
