Study on Disaster Characteristics of Huaxi Autumn Rain and Trigger Mechanisms for Weather Index Insurance

This study addresses the basis risk in weather index insurance for Huaxi autumn rains by proposing a semantics-based disaster classification system that decomposes heterogeneous yield-loss events into homogeneous subgroups, demonstrating that while this approach significantly improves trigger accuracy for specific maize scenarios, it remains constrained by small-sample limitations in complex rice disaster pathways.
