Short Summary

This study systematically investigates the spatiotemporal characteristics and propagation mechanisms of meteorological drought to hydrological, agricultural, and ecological droughts in the Yellow River Basin (YRB) from 1982 to 2018, revealing distinct propagation patterns and regional disparities.

Objective

• To systematically investigate the propagation characteristics and spatiotemporal structure of meteorological drought to hydrological, agricultural, and ecological droughts in the Yellow River Basin from the perspective of drought events.
• To elucidate the propagation mechanisms among different types of droughts to enhance drought early warning capabilities and achieve coordinated regulation across multiple systems.

Study Configuration

• Spatial Scale: Yellow River Basin (YRB), China.
• Temporal Scale: 1982–2018 (37 years).

Methodology and Data

• Models used: Run theory, optimized drought migration model.
• Data sources: Multi-source dataset.

Main Results

• In the Yellow River Basin, the propagation time of droughts shows that hydrological drought occurs earlier than agricultural and ecological droughts.
• The drought propagation process in the YRB exhibits two typical patterns: a "high-frequency and fast-response" type (corresponding to regions with strong meteorological forcing) and a "low-frequency and slow-response" type (corresponding to regions with human activities).
• Meteorological droughts in the YRB occur frequently and expand rapidly.
• Hydrological droughts exhibit strong accumulation and persistence, with a response process markedly more pronounced than that of agricultural and ecological droughts, displaying significant regional disparities.

Contributions

• Contributes to a deeper understanding of the propagation mechanisms among multiple drought types.
• Provides a theoretical foundation and technical support for developing hierarchical early warning and coordinated response systems tailored to different sectors.
