Districtwise drought climatology of the Southwest monsoon season over India based on standardized precipitation index (SPI)
In this new study IMD examines district-wise and all India drought climatology over India for southwest monsoon season using using Percent of Normal(PN) & Standardized Precipitation Index(SPI).Compares drought climatology based on SPI with that based on PN to show that SPI is a better index for monitoring drought conditions over smaller spatial scales like districts, subdivisions etc.
