Title

COMPARISON OF SEVEN METEOROLOGICAL INDICES TO MONITOR DROUGHT STATUS IN DROUGHT PRONE DISTRICTS OF RAJASTHAN

Abstract

There are various drought indices which are normally used in drought monitoring and risk management. Rainfall, temperature, evaporation and other hydro meteorological parameter are crucial part to assessment of drought. Thousands of drought indices have been developed in the world in recent past years for this purpose. This paper identifies the applicability and comparison of drought indices in drought prone area in Rajasthan state by assessing the performance of seven drought indices. The indices include Standardized Precipitation Index (SPI), Percentage of Normal (PNI), Deciles Index, (DI), China Z Index (CZI), Modified China Z Index (MCZI), Rainfall Anomaly Index (RAI), Z score index. These indices are compared by using 53 years of rainfall data (1950-2002) in seven drought prone district in. The performance, efficiency and significance are also tested by applying different statistical tests. The comparison of seven drought indices also based on relative drought frequency and drought classes. In result, Z score index is most suitable indices and CZI and MCZI also showing good result so Z score index can be used instead of SPI in drought prone district of Rajasthan. RAI is least efficient and its relative error is also high so RAI is least suitable indices for drought monitoring.
