This study suggests a definition and criterion on the TC approaching to the KP (KP-approach TC) additionally, which is more obvious and objective than the KP-influence TC. In this study, the criterion on the KP-approach TC is determined when the TC's center from the RSMC best track data encounters the box areas of 28 N~40 N and 20 E~38 E. The range is chosen by finding a minimum area that includes all official KPinfluence TCs except three TCs that affected the KP as a tropical depression (TD). Statistical analysis reveals that, among total,537 TCs that occur in the western North Pacific during 95-2008, the KP-approach TC was 472, the KP-influence TC was 87, and the KP-landfall TC was 87. August was the month that the largest TCs approach and influence to the KP. Finally, this paper suggests to determine the KP-influence TC by the strong wind and heavy rain advisories in the KP based on the observation after the storm's passage.

50 객관적인 태풍 통계자료 구축을 위한 한반도 근접 태풍 의 정의 및 기준 설정 향 태풍 보다 42개가 더 많았다(Table, Fig. 4). 한 편, 제 3안에 포함되지 않은 한반도 영향 태풍 은 4 개(724, 7420, 763, 7709)로 나타났다. 이들 태풍 중 에 3개(724, 7420, 763)는 모두 제 안 구역도 통과 하지 않았으며, 열대저압부로 한반도에 영향을 준 태 풍이었다. 7709는 32 N 이남으로 지나갔기 때문에 제 3안에 포함되지 않았다(Fig. 2). 이 태풍은 977년 9 월 0일에 서귀포에서 최대풍속 7.7 m/s와 최대순간 풍속 29.5 m/s를 기록하여 기상특보 기준을 넘어 그 당시에 한반도에 영향을 주었음을 알 수 있다. 따라 서 제시된 제 3안 역시 열대저압부를 제외하더라도 한 개의 한반도 영향 태풍(7709)을 포함할 수 없어 한 반도 근접 태풍의 기준으로 사용하기에는 수정이 필 요하다. 제 안 최종안 한반도 근접 태풍 기준 설정을 위해 태풍백서의 한 반도 영향 태풍 중에 위에 제시된 세 개의 구역을 지 나가지 않은 태풍에 대해 기상관측자료를 이용하여 한반도 영향 여부를 조사였다. 그 결과 한반도 근접 태풍 에 속하지 못했던 한반도 영향 태풍 의 개수가 제 안은 9개, 제 2안은 3개, 제 3안은 4개로 나타났으 며, 그 시기는 모두 기상특보 발효기준에 해당되는 강 수 또는 풍속이 기록되어 한반도에 어느 정도 태풍에 의한 영향이 있었음을 알 수 있었다(Table, Table 2). 이들 태풍 중에 열대저압부로 한반도에 영향을 미친 태풍은 RSMC의 태풍경로 자료에서 열대저압부로 바 뀐 후부터는 태풍정보가 기록되지 않아 실제로 한반 도에 근접하였더라도 그 기록이 남지 않는다. 따라서 RSMC의 자료만으로는 열대저압부를 한반도 근접 태 풍 으로 분류하기에는 한계가 있다. 이러한 이유 때문 에 본 연구에서는 열대저압부로 한반도 영향을 미친 태풍을 제외한 모든 태풍이 한반도 근접 태풍 으로 분류될 수 있도록 새로운 기준(제 4안)을 제시하였다. 제 4안은 열대저압부를 제외한 한반도 영향 태풍 이 모두 포함되도록 앞의 세 가지 안을 절충하여 위 도는 기상청의 태풍비상구역을 사용하고, 경도는 기 후예측과의 기준을 사용한 새로운 구역(28 N~40 N, 20 E~38 E)으로 정하였다(Fig. 5). 이 기준에 따르 Same as in Fig., but for the Criterion 3 (32 ~40, 20 ~38, black box).
