Sunset Bores Over the Southern North China Plain

Le résumé fourni par la source

Abstract This study examines the genesis of atmospheric bores near sunset and their role in initiating and maintaining late‐afternoon mesoscale convective systems (MCSs) over the Southern North China Plain. A key finding is that 20% of documented bore occur during the sunset period. These bores form in the local environment preconditioned by the convective outflows from late afternoon MCSs, or by sea breezes that peak at this time. These bores aid in initiating and maintaining afternoon convection, subsequently favoring the development of nocturnal MCSs and associated bores. While bore research often concentrates on their impact on nocturnal MCSs, this study highlights that accurately predicting the diurnal cycle of MCSs requires properly representing bores. Thus, it helps address the long‐standing challenge of simulating the diurnal cycle of convective rainfall in weather and climate models.
