Drought propagation as a nonlinear amplifier of ecohydrological damage

Communications Earth & Environment
Meteorological drought can propagate to soil and ecological droughts, triggering cascading disruptions in ecosystem functioning. However, whether the ecohydrological damage—the sum of standardized vegetation greenness and soil moisture losses—is ...

From meteorological to agricultural drought: Propagation time and probabilistic linkages

Journal of Hydrology: Regional Studies, 2023
Study region: Yangtze River Basin, China Study focus: As agricultural drought originates from meteorological drought, exploring the propagation from meteorological to agricultural drought is an important step in providing early warning of agricultural ...

Understanding meteorological, runoff, and agricultural drought propagation and their influencing factors in an ensemble of multiple datasets [PDF]

Hydrology and Earth System Sciences
Understanding the propagation of diverse drought conditions is essential for effective drought preparedness. This study evaluated the propagation of meteorological, runoff, and agricultural droughts across global land areas from 1958 to 2024 using an ...

Investigation of the propagation of meteorological to hydrological drought and water required to recover from drought over Ethiopian basins

Journal of Water and Climate Change, 2023
This study investigates drought propagation from meteorological to hydrological and streamflow required to recover from drought in four sub-basins: Genale, Tekeze, Awash, and Baro basins of Ethiopia.

Drought propagation in space and time: the role of groundwater flows

Environmental Research Letters, 2022
Droughts cause large economic and social impacts all over the world. During drought, groundwater maintains streamflow and can help to mitigate impacts. It governs how drought propagates through the hydrological cycle.

Spatiotemporal Characteristics of Droughts and Their Propagation during the Past 67 Years in Northern Thailand

Atmosphere, 2022
Droughts grow concurrently in space and time; however, their spatiotemporal propagation is still not fully studied. In this study, drought propagation and spatiotemporal characteristics were studied in northern, northeastern, and central Thailand (NNCT).

A New Perspective on Drought Propagation: Causality

Geophysical Research Letters, 2022
AbstractThe essence of propagation from meteorological to hydrological drought is the cause‐effect relationship between precipitation and runoff. This study challenged the reliability of applying linear or non‐linear correlation (i.e., closeness/similarity, a non‐directional scalar) to study drought propagation (i.e., causality, a directional vector ...

Automation of hydrological drought typology to study drought propagation in a tropical catchment [PDF]

, 2021
Understanding how droughts propagate through the hydrological cycle from precipitation to streamflow and groundwater is important for improving water and risk management policies. At the catchment scale, the analysis of drought propagation and classification into drought types is usually done manually, which can be time consuming and difficult to ...
