Short summary
Due to the specific applicability of drought impact indicators, this study identifies which drought indicators are suitable for characterising drought impacts and the contribution of vulnerability factors. The results show that the relationship varies across different drought impacts and cities; some factors have a strong positive correlation with drought vulnerability. This study can support drought planning work and provide background for the indices used in drought monitoring applications.
