Drought propagation in Northern China Plain: A comparative analysis of GLDAS and MERRA-2 datasets

Drought impact is closely related to water deficit phases within the hydrological cycle, and to drought propagation (the complex evolutions from meteorological drought to hydrological drought and to soil moisture drought). Besides the qualitative description, the quantitative analysis of drought propagation is still limited so far. Therefore, in this study, the propagation from meteorological to hydrological and to soil moisture droughts have...
