Short summary

This study develops a long-term database of mesoscale convective systems (MCSs) across the Asian monsoon region and evaluates their impacts on hazardous weather. The results demonstrate that MCSs dominate regional precipitation and are strongly associated with severe convective hazards. Notably, increasing trends in both MCS activity and associated hazard potential are evident in eastern China, underscoring the urgent need to strengthen disaster prevention and response measures.
