Evaluation of meteorological drought indices using meteorological datasets

, 2022
Abstract Drought indices are a suitable tool for management measures and dealing with the phenomenon of drought and are widely used worldwide. In this study, the drought indices of the SPI, CZI, ZSI, and MCZI in different monthly periods (1, 3, 6, 9, 12, 18, 24 and 48) and the DI and PNI in different monthly, seasonal and annual periods in ...

Meteorological and Hydrological Drought Analysis of The Kızılırmak Basin

Black Sea Journal of Agriculture, 2023
Global climate variation revealing its effects intensely after the Industrial Revolution, have increased extremely with the rise in the number and variation of flood and drought problems worldwide within the years from1990 to 2000. Our country is strongly suffering from this climate variation and its undesired consequences increasing every year ...

Characteristics of Propagation of Meteorological to Hydrological Drought for Lake Baiyangdian in a Changing Environment

Atmosphere, 2022
The analysis of drought propagation has garnered mounting attention in the changing global environment. The current studies tend to focus on the propagation characteristics from meteorological to hydrological drought in rivers. Lakes, despite being a key

Hydrological drought forecasts outperform meteorological drought forecasts

Environmental Research Letters, 2020
One of the most effective strategies to reduce the impacts of drought is by issuing a timely and targeted warning from month to seasons ahead to end users. Yet to accurately forecast the drought hazard on a sub-seasonal to seasonal time scale remains a challenge, and usually, meteorological drought is forecasted instead of hydrological drought ...

Correction method of heavy rainfall in the Sichuan Basin based on multi-model forecasting

暴雨灾害
The terrain and landform of the Sichuan Basin are complex, which also make the forecast of heavy rainfall challenging, therefore the correction of the model precipitation forecast products is the crucial method to improve the quality of heavy rainfall ...

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

Terrestrial, 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 ...

Comparison of Meteorological Drought Indices in Tanzania Using the Meteorological Drought Monitoring (MDM) Software Package

Tanzania Journal of Engineering and Technology
Low precipitation, substantial evaporation, and an unequal distribution of precipitation throughout the area are the characteristics of drought, a climatic abnormality. This study used the Meteorological Drought Monitoring (MDM) software and monthly rainfall data from the Tanzania Meteorological Authority (TMA) to examine and compare the Deciles Index (

Vegetation Drought Vulnerability Mapping Using a Copula Model of Vegetation Index and Meteorological Drought Index

Remote Sensing, 2021
Since vegetation is closely related to a variety of hydrological factors, the vegetation condition during a drought is greatly affected by moisture supply or moisture demand from the atmosphere.

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

Advanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...
