Mean Drought Index
Mean Drought Index data was reported at 1.262 NA in 2021. This records an increase from the previous number of -0.735 NA for 2020. Mean Drought Index data is updated yearly, averaging 0.035 NA from Dec 1960 (Median) to 2021, with 62 observations. The data reached an all-time high of 2.619 NA in 1963 and a record low of -1.872 NA in 1987. Mean Drought Index data remains active status in CEIC and is reported by World Bank. The data is categorized under Global Database’s Sri Lanka – Table LK.World Bank.WDI: Environmental: Climate Risk. The SPEI fulfills the requirements of a drought index since its multi-scalar character enables it to be used by different scientific disciplines to detect, monitor, and analyze droughts. Like the sc-PDSI and the SPI, the SPEI can measure drought severity according to its intensity and duration, and can identify the onset and end of drought episodes. The SPEI allows comparison of drought severity through time and space, since it can be calculated over a wide range of climates, as can the SPI.;Global SPEI database (SPEIbase). https://spei.csic.es/database.html;;
