This study analyzed drought climatology for North Korea from 1982 to 2008. The Effective Drought Index (EDI; Byun and Wilhite, 1999) was used to quantify drought. The index was calculated by using daily precipitation data at 26 stations. First, hierarchical cluster analysis was implemented based on the similarity of drought characteristic. As a result, the drought sub-regions in North Korea largely classified into the northern east coast region (G1), the northern region (G2), the southern east coast region (G3) and the southern region (G4). Second, the drought map was constructed in order to confirm easily the spatiotemporal distribution of droughts for 27 years. As a result, the droughts (EDI≤ -0.7) occurred 27 times at entire region. The highest frequency was observed in G1 (41 times) and the lowest in G2 (16 times). On average, most droughts were the short-term drought of less than 200 days. The long-term droughts of more than one year occurred 2 times for 27 years (1997-1998, 1999-2001). The longest drought was continued for 1360 days from August 1996 to May 2000 at G3. Also, through drought map, it was observed the severe drought (EDI ≤ -2.5) occurred at G4 in May 2001.
