This paper introduces the East Asian drought monitoring system that has been operational since 2008 (http://atmos.pknu. ac.kr/~intra2). It provides the spatial and temporal distribution of droughts using variables such as the drought intensity and duration. The main feature of this system is the effective drought index (EDI; Byun and Wilhite 1) in which the drought intensity is calculated by considering cumulative precipitation as a weighting function of time. In addition, this system provides
