Heavy precipitation events (HPEs) in the Yangtze River Valley (YRV) pose persistent threats to population safety and infrastructure. This study classifies five population‐weighted HPE types (P1–P5) and examines their underlying dynamics using multiscale window transform and canonical energy transfer framework. Each type links to distinct circulation patterns. During 1979–2020, P1 and P2 are associated with Meiyu front systems,...

Meteorological flash droughts (MFDs) typically precede agricultural flash droughts, with their propagation risk heightened by intensified land‐atmosphere coupling under global warming. Although China is highly vulnerable to such events, systematic analyses of the spatiotemporal patterns and drivers of MFDs remain limited. Here, we employ the operationally used Meteorological Drought Composite Index (MCI) to characterize MFDs a...

A large and highly polyploid genome, long breeding cycles, low narrow-sense heritability of yield and its components, and persisting yield stagnation continue to challenge sugarcane variety improvement through both conventional and molecular breedings. To address this, this study developed an efficient phenotype-based concurrent multi-trait prediction framework using artificial intelligence, leveraging 2700 parent combinations...
