The merger of convective clouds in severe precipitation associated with the Meiyu front occurred near Nanjing during 4-5 July 2003 is investigated using satellite observational analyses and numerical simulations with the Weather Research and Forecast version 3.2. It is found that the merger of convective clouds plays a crucial role in the excessive storm. The severe rainfall event experiences a multi-scale organized process ranging from triggered convective bulbs, growing convective cells, to the formation of the convective complex. The development of convections causes the large-scale dynamic and thermodynamic environment change, which in turn favors the organized processes of convective systems and promotes multi-scale coupling of the nonlinear interaction between convections and its large-scale environment.
