A Climatological Feature of Typhoon Making Landfall over the Korean Peninsula

The present study has analyzed the climatological characteristics of the tropical cyclones (TCs) made landfall over the Korean Peninsula (KP) during the period of 1951 to 2004. Both the landfall frequency and the intensity of KP-landfall TCs have rapidly increased since the late 1980s. Especially, the frequency of TCs with an intensity greater than tropical storm remarkably have increased. The main landfalling track of KP-landfall TCs has also been changed. The TCs in the past mainly landed at the middle and northern regions of the west coast of the KP, but in recent years, the TCs have changed to land at the south coast and then pass through the east coast of the KP. That is, the main landfalling track tends to make a southeastward shift. This shift was also discovered in the trend analysis of the recurving location of the KP-landfall TCs and of the location of the western North Pacific High (WNPH). This kinds of eastward shift are due to the southward advance of the upper-level trough of the mid-latitude and simultaneously the eastward expansion of the subtropical monsoon westerly. Meanwhile, the genesis location of KP-landfall TCs has been the fartheast eastward only in the 2000s, but the trend toward an eastward shift has not been seen.
