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 ...

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 ...

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 ...

A reflectivity factor correction algorithm for X-band phased array radars
暴雨灾害, 2023 The difference between reflectivity factors observed by different radars observing the same target affects the performance of the multi-radar mosaic. For X-band radars without beam blocking, this difference is mainly caused by calibration deviation and ...
