Indicator Definition:
The Standardized Precipitation Evapotranspiration Index (SPEI), or Mean Drought Index, calculated for a 12-month period, has been found to be closely related to drought impacts on ecosystems, crop, and water resources. The SPEI is designed to take into account both precipitation and potential evapotranspiration (PET) in determining drought.
The indicator "Mean Drought Index (projected change, unitless)" stands at -1.52 as of 12/31/2023.
Regarding the One-Year-Change of the series, the current value constitutes an increase of 0.1769 compared to the value the year prior.
The Serie's long term average value is -0.323. It's latest available value, on 12/31/2023, is -1.20 lower, compared to it's long term average value.
The Serie's change from it's minimum value, on 12/31/2021, to it's latest available value, on 12/31/2023, is +0.8536 .
The Serie's change from it's maximum value, on 12/31/1976, to it's latest available value, on 12/31/2023, is -4.58 .
