AB: The Aggregate Drought Index (ADI) (Keyantash and Dracup, 2004) was developed as a tool to describe the intensity of drought across multiple hydrologic reservoirs. The ADI is a principal-components based index, which examines water shortages and abundances with regards to precipitation, evaporation, streamflow, reservoir storage, soil moisture, and alpine snowpack. In this regard, the ADI aggregates water deficiencies commonly segregated into meteorological, hydrological, and agricultural forms of drought. The ADI will be used to quantify drought severity in three California climate divisions from circa 1970 through the record dry conditions of water year 2007.
