What the extent of meteorological drought could trigger the corresponding hydrological drought with different levels? This question is an important topic in the field of drought propagation, which however has not been resolved. Therefore, a novel model based on a Bayesian network was proposed to address this issue in this study.

Comparison of Meteorological Drought and Hydrological Drought Index
Journal of the Korean Water Resources Association, 2015본 연구는 기상학적 가뭄지수가 수문학적 가뭄에 대한 모사정도를 검토하였다. 기상학적 가뭄지수 중에서 강수량을 변수로 하는 SPI(Standardized Precipitation Index)와 강수량 및 증발산량을 변수로 하는 SPEI(Standardized Precipitation Evapotranspiration Index)를 이용하였고, 수문학적 가뭄 평가를 위하여 월 총 유입량과 하천수 가뭄지수인 SDI(Streamflow Drought Index)를 계산하여, 최종적으로 기상학적 가뭄지수와 수문학적 가뭄지수와의 상관정도를 분석하였다.

Characteristics of meteorological drought in Bangladesh
Natural Hazards, 2012Meteorological drought events occur in Bangladesh are diagnosed using monthly rainfall and mean air temperature from the surface observations and Regional Climate Model (RegCM) by calculating Standardized Precipitation Index (SPI) and Palmer Drought Severity Index (PDSI) for the period 1961–1990.

Monitoring Drought: An Evaluation of Meteorological Drought Indices
Geography Compass, 2009Abstract A uniform method for defining, monitoring and quantifying the severity of drought conditions does not exist. This article introduces some of the tools (e.g. drought indices) that are commonly used in the United States to monitor meteorological drought, describes the strengths and weaknesses of these tools, and makes ...

Indices for Meteorological and Hydrological Drought
2021This review chapter describes two physical forms of drought, meteorological and hydrological drought, and introduces a variety of specialized drought indices which may be used to quantify the intensity and severity of those drought forms. Meteorological and hydrological drought indices include the Palmer drought severity index (PDSI), rainfall deciles,

Meteorological Drought Occurrence in Slovakia
2017Slovakia is located in the Central Europe, and its complex surface consists of mountains, valleys, but also lowlands, which are crucial for agricultural production. In the neighbouring countries, especially in Hungary and the Czech Republic, there has been paid great attention to drought occurrence for a longer time.

Sahel drought: Meteorological or agricultural?
International Journal of Climatology, 1989AbstractMeteorological definitions of drought are deemed to reveal little of the effects of water deficiencies upon the inhabitants of arid regions. An agricultural definition of drought is obtained using a water‐balance model of the moisture available to millet (Pennisetum typhoides).The model accepts inputs of rainfall, potential evapotranspiration ...

Propagation of Meteorological Drought to Groundwater Drought in India
Groundwater drought poses a growing threat to water security in India, as groundwater supplies support agriculture, ecosystems, and domestic use. Although meteorological and hydrological droughts and their propagation have been studied, the propagation of drought into groundwater systems in India has not been examined.Aayush Aayush, Vimal Mishra
