초록

본 연구의 목적은 파키스탄의 강수지역을 구분하는 것이다. 파키스탄 강수 특성의 이해를 증진시키기 위해 강수 지역을 구분하였다. 강수 형태는 순별 강수량 자료를 이용하여 인자분석과 군집분석 기법으로 분석하였다. 연구에 사용된 자료는 파키스탄 기상청에서 제공하는 32개 기상 관측소의 자료로 연구 기간은 1980년에서 2006년까지이다. 인자분석의 결과 추출된 3개의 인자는 전체 변동의 94.60%를 설명한다. 강수 지역은 강수 특성의 공간적 분포를 이해하기 위해 군집분석을 하였다. 군집분석은 Ward법을 이용하여 분석하였다. 연구 결과 강수 지역은 6개의 지역으로 구분되었다. 지역의 경계는 Baluchistan 고원, Indus 평야, Hindu Kush 산맥과 Himalaya 산맥 같은 지형을 기준으로 구분하였다.

This study is aimed to classify rainfall regions in Pakistan. Classification of rainfall regions is essential to understand rainfall patterns in Pakistan. Rainfall patterns have been investigated using a factor and cluster analysis technique by 10-days rainfall parameter. The data used here have been obtained from 32 specific weather stations of PMD (Pakistan Meteorological Department) for the period of January 1980 to December 2006. The results obtained from factor analysis provide three factors and these three factors accounts for 94.60% of the total variance. For a better understanding of rainfall regions, cluster analysis method has been applied. The clustering procedure is based on the Wards method algorithm. Overall, these rainfall regions have been divided into six groups. The boundary of the region is determined by the topology such as Baluchistan plateau, Indus plain, Hindu Kush and Himalaya ranges.
