ANALISIS INDEKS KEKERINGAN DI DAS ROKAN PROVINSI RIAU MENGGUNAKAN DATA CFSR
ABSTRACT: One of important
component of the national drought strategy is a comprehensive drought
monitoring system that can provide a warning at the early and the end stage of
the drought, determine the severity level, and disseminate the drought
information to various sectors. Due to the drought issues, this research is
aimed to analyze the drought index on the Rokan Watershed, Riau Province.
Drought index were analyzed using two methods, i.e. KBDI (Keetch-Byram Drought
Index) and SPI (Standardized Precipitation Index). Due to the limited data from
existing observation stations on the Rokan watershed, this research was using
the data from the Climate Forecast System Reanalysis (CFSR) of the The National
Centers for Environmental Prediction (NCEP). The CFSR rainfall data were
corrected before the data were used. KBDI and SPI methods were used to analyze
the spatial and temporal drought that occurred on the Rokan watershed. The
relationship between distributions of the drought and hotspot was shown better
relationship by the KBDI method compared with SPI method.
