Estimating propagation probability from meteorological to ecological droughts using a hybrid machine learning copula method [PDF]
Hydrology and Earth System Sciences, 2023 The impact of droughts on vegetation is essentially manifested as the transition of water shortage from the meteorological to ecological stages. Therefore, understanding the mechanism of drought propagation from meteorological to ecological drought is ...

A Global Probabilistic Dataset for Monitoring Meteorological Droughts [PDF]
Bulletin of the American Meteorological Society, 2020 AbstractAccurate and timely drought information is essential to move from postcrisis to preimpact drought-risk management. A number of drought datasets are already available. They cover the last three decades and provide data in near–real time (using different sources), but they are all “deterministic” (i.e., single realization), and input and output ...

AutoML-Based Drought Forecast with Meteorological Variables
CoRR, 2022 A precise forecast for droughts is of considerable value to scientific research, agriculture, and water resource management. With emerging developments of data-driven approaches for hydro-climate modeling, this paper investigates an AutoML-based framework to forecast droughts in the U.S.

Meteorological Drought Assessment in Sharjah, UAE Using Drought Indices [PDF]
International Journal of Environmental Science and Development, 2022 Drought is a natural disaster that significantly affects environmental and socio-economic conditions. It occurs when there is a period of below average precipitation in a region, and it results in water supply shortages affecting various sectors and life adversely. Droughts impact the ecosystems, crop production, and erode livelihoods.

Meteorological and hydrological drought monitoring using several drought indices [PDF]
Applied Water Science, 2021 AbstractWith respect to the necessity of comprehensive studies on drought and also high damages that caused by drought, this research studied the meteorological and hydrological droughts. In this study, Lighvan, Navroud and Seqez basins with different climates were selected.

Hydrological drought response to meteorological drought in the Iberian Peninsula [PDF]
Climate Research, 2013 In this study we assessed the impact of meteorological droughts on streamflow droughts in 187 river basins of the Iberian Peninsula. For each basin we correlated the 1 mo to 48 mo standardized precipitation index (SPI) with the standardized streamflow index to assess the response time of streamflow droughts to the SPI, and to determine the best ...

Drought impact links to meteorological drought indicators and predictability in Spain [PDF]
Hydrology and Earth System Sciences, 2021 Abstract. Drought affects many regions worldwide and future climate projections imply that drought severity and frequency will increase. Hence, the impacts of drought on the environment and society will also increase considerably. Monitoring and early warning systems for drought rely on several indicators; however, assessments on how these indicators ...
