초록

This study has examined influences of tropical cyclone (TC) landfalls on the Gyoengsangbuk‐do region, located in southeast of Korea, for the period 1978－2006. This region is known as one of major pass ways of landfalling TCs, and has many cultural properties including Bulguksa, Sukgulam, etc. Thus the influences caused by TCs (i.e., TC damages) may be larger than elsewhere in the nation. Here, TC influence is defined as the cases of strong instantaneous wind speed ( 20 m s‐¹) and heavy rainfall ( 100 mm day‐¹) at each station. This study analyzed long‐term trends of TC influences and the relationship with TC tracks are examined. As a result, it is found that large increase of the heavy rainfall cases along the coastal region. By contrast, there are marginal changes in the strong wind speed associated with TC landfalls. Further, it is also found that the cases of the heavy rainfall only are related with TCs passing through the Yellow Sea and the cases of both the strong wind and the heavy rainfall are related with TCs landing from southern Korea.
