Abstract:
By using not only the daily precipitation and temperature data at 77 stations of Anhui Province during 1961-2009, but also the soil moisture data in all stations from the start of the record to 2009, this paper analyzes the application of the improved CI index in Anhui Province. The results show that in the aspects of statistic characteristics, its correlation to soil moisture, the spatial distribution of drought and so on, the improved CI (NCC2CI) index inherits the advantages of the OldCI index, but in the aspect of diagnosis of the daily evolution of the drought process, the NCC2CI index has much improvements compared with the OldCI index. As to the drought monitoring in Anhui Province, the NCC2CI index is superior over the OldCI index obviously.
