Changes in Typhoon Activities and Regional Precipitation Variability over the Korean Peninsula according to Different Phases of El Niño

Figure 2

Composite differences of tropical cyclones (TCs) passed through the Korean domain (shown in a solid blue line) during CT and WP El Niño years. The solid (dashed) line indicates the seasonal mean (June–September) of the WNP subtropical high (5880 gpm) during the WP (CT) El Niño years. Mean TC genesis positions were shown by typhoon symbols in blue (red) during the CT El Niño years (WP El Niño years). Inset: empirical probability distribution for central pressure (hPa) of TCs. Violin plots (box plot-density trace synergism) were applied for central pressure (hPa) of TCs affecting the Korean Peninsula during CT/WP El Niño years. Numbers inside the inset represent the average value of central pressure of TCs for each case.
