A Simulation Study of the Mesoscale Convective Systems Associated with a Meiyu Frontal Heavy Rain Event

In this study, evolution of the mesoscale convective systems (MCSs) within a Meiyu front during a partic-ularly heavy rainfall event on 22 June 1999 in East China was simulated by using a nonhydrostatic numerical model ARPS (Advanced Regional Prediction System). Investigations were conducted with emphasis on the impact of the interaction among multi-scale weather systems (MWSs) on the development of MCSs in the Meiyu frontal environment. For this case, the development of MCSs experienced three different sta...
