华北黄淮极端雨强多尺度过程和物理模型
Recognition of multi-scale processes and a physical model for extreme rainfall mechanisms in North China and the Huanghuai region
摘要
Abstract
In recent years,extreme rainfall events such as the"21·7"Henan and"23·7"Beijing-Tianjin-Hebei storms have frequently impacted North China and the Huanghuai region(North China-Huanghuai region).These events exposed significant gaps in our understanding of their physical mechanisms.This article summarizes recent researches on spatial-temporal features,synoptic patterns,mesoscale convective systems(MCSs),and microphysical structures of extreme rainfall.By combining multi-source observations and model simulations,the study highlights the multiscale processes—from large-scale circulation to microphysics—that jointly shape rainfall intensity.A multiscale pattern recognition method is proposed to improve the identification of extreme events.Two distinct MCS types—warm-type and deep-convective-type—are characterized,especially in terms of raindrop spectra and hydrometeor composition.A multiscale conceptual model tailored to North China is presented,offering insights to improve forecasting and model representation of extreme rainfall processes.关键词
