Abstract Based on GRACE/GRACE-FO gravity satellite data from 2004-2021, we invert the spatial and temporal changes of terrestrial water storage in the Yellow river basin and construct both a drought index model and a flood factor model to analyze and study the extreme climate phenomena in the Yellow river basin. The results show that the terrestrial water storage in the Yellow river basin decreased at a rate of 0.56 cm/a during 2004 to 2021 considering cyclical seasonal characteristics, showing a surplus in summer and autumn and a deficit in spring and winter. The drought index model monitored 22 extreme droughts and 37 severe droughts in the Yellow river basin, and the scope of drought events covered the entire Yellow river basin. The flood factor model detected 118 flood events in the Yellow river basin, with floods mostly occurring in summer and autumn when rainfall was more abundant, during which the capacity of terrestrial water storage of the Yellow river basin was weaker. The meteorological results detected by the drought index model and flood factor model constructed with GRACE/GRACE-FO gravity satellite data are consistent with actual physical observations, reflecting the climactic conditions occurring in the Yellow river basin and providing a favorable tool for the study of extreme climate.
