Different driving mechanisms during two consecutive flash heavy rainfalls over the Sichuan Basin in China: A case study

Key Points

• Flash heavy rainfall events in the Sichuan Basin are influenced by specific meteorological conditions and hydrological responses.
• During two consecutive events, driving mechanisms were identified, showing varied impacts on local ecosystems and infrastructure.
• Analysis of meteorological data revealed patterns associated with intense precipitation and its effects on hydrology and land use.
• Understanding these driving mechanisms may enhance prediction models, improving preparedness for future flash flooding events.
