| Abstract: | Aiming at the fact that the mesoscale convective systems develop on or in the south vicinity of the Meiyu front,lasting a long time and producing rainstorms along the Yangtze River valley,a series of three-dimensional idealized numerical experiments are carried out to investigate the effect of moisture difference between the two sides of the Meiyu front,to reveal the impacts of basic flow and wind vertical shear upon the development of the mesoscale convective systems along the Meiyu front,and to show the c... |
