Estimating the water needed to end the drought or reduce the drought severity in the Carpathian region
(Copernicus Publications, 2015-01)
A drought severity climatology for the Carpathian region has been produced using the self-calibrating Palmer Drought Severity Index (Sc-PDSI) for the period 1961-2010. Using the Sc-PDSI and the assumptions of the Palmer ...
Local perception of drought impacts in a changing climate: the mega-drought in central Chile
Droughts are a recurrent and complex natural hazard whose frequency and magnitude are expected to increase with climate change. Despite the advances in responding and adapting to droughts (with the development of new ...
Five Hundred Years of Hydrological Drought in the Upper Colorado River Basin
This article evaluates drought scenarios of the Upper Colorado River basin (UCRB) considering multiple drought variables for the past 500 years and positions the current drought in terms of the magnitude and frequency. ...
The mandacaru did not blossom: Positivist science at the service of drought control in 1877-1879
