Study on the propagation law of meteorological drought to hydrological drought under variable time Scale: An example from the Yellow River Water Supply Area in Henan

open access: goldEcological Indicators, 2023
To study the propagation law of meteorological droughts to hydrological droughts under variable time scales, and to reveal the synchronisation gap and lag time of hydrological droughts compared to meteorological droughts, and the lag degree of ...

Propagation Characteristics and Influencing Factors of Meteorological Drought to Soil Drought in the Upper Reaches of the Shiyang River Based on the Copula Function [PDF]

open access: goldLand
Drought propagation is a complex process, and understanding the propagation mechanisms of meteorological drought to soil drought is crucial for early warning, disaster prevention, and mitigation.

Investigation of drought propagation in South Korea using drought index and conditional probability

open access: goldTerrestrial, Atmospheric and Oceanic Sciences, 2018
Meteorological drought commonly originates from precipitation deficit and is then propagated to agricultural and hydrological droughts. Since drought impacts are more directly related to agricultural and hydrological systems of human society, it is important to understand the drought propagation process for reducing drought impacts.

Cascading droughts: Exploring global propagation of meteorological to hydrological droughts (1971–2001)

open access: hybridScience of The Total Environment
An understanding of the spatiotemporal behaviour of Meteorological drought (MD) and Hydrological drought (HD) is crucial for analysing how drought propagation occurs. Here, drought events were treated as three-dimensional grid structures spanning space (latitude and longitude) and time.

Propagation dynamics and causes of hydrological drought in response to meteorological drought at seasonal timescales [PDF]

open access: goldHydrology Research, 2022
According to the widely accepted definition of drought, meteorological and hydrological droughts originally develop from rainfall and runoff deficits, respectively.

Evaluation of drought propagation in an ensemble mean of large-scale hydrological models [PDF]

open access: gold, 2012
Hydrological drought is increasingly studied using large-scale models. It is, however, not sure whether large-scale models reproduce the development of hydrological drought correctly.

Probabilistic long‐term hydrological drought forecast using Bayesian networks and drought propagation [PDF]

open access: yesMeteorological Applications, 2020
Effective drought mitigation plans that can handle severe drought conditions require reliable drought forecasts. A probabilistic hydrological drought forecasting method was developed using Bayesian networks that incorporate dynamic model predictions and ...

Multifractal characterization of meteorological to agricultural drought propagation over India. [PDF]

open access: yesSci Rep
AbstractAgricultural drought affects the regional food security and thus understanding how meteorological drought propagates to agricultural drought is crucial. This study examines the temporal scaling trends of meteorological and agricultural drought data over 34 Indian meteorological sub-divisions from 1981 to 2020.

Spatial and Temporal Global Patterns of Drought Propagation [PDF]

open access: yesFrontiers in Environmental Science, 2022
Drought is the most expensive natural hazard and one of the deadliest. While drought propagation through standardised indices has been extensively studied at the regional scale, global scale drought propagation, and particularly quantifying the space and

Drought self-propagation in drylands due to land–atmosphere feedbacks [PDF]

open access: bronzeNature Geoscience, 2022
Reduced evaporation due to dry soils can affect the land surface energy balance, with implications for local and downwind precipitation. When evaporation is constrained by soil moisture, the atmospheric supply of water is depleted, and this deficit may propagate in time and space.
