The mechanism was similar to the equivalent barotropic warm core structure. The Conditional Instability of the Second Kind was the primary mechanism of development and maintenance for MCSs in case 2005. As the MCSs intensified and persisted, the latent heating was highly efficient in producing significant enhancement of Mei-Yu front systems. The LLJ intensified by Coriolis acceleration of ageostrophic wind was induced by the effect of latent heat release. The LLJ and the effect of latent heat released reinforce each other in convection system through a positive feedback process.

Numerical tests are also conducted to investigate the microphysical effects to the mesocale convective systems. The evaporation of raindrops can strengthen the surface "cold pool" to decease the temperature of rainfall center. The condensation of vapor can lower the air pressure and increase the convergence and updraft so that the convective echo develops stronger. The melting of graupel can cool the air to restrain the convective activity. The falling of precipitation particles can increase the downdraft and induce the outflow nearly the surface. The effect of condensation is the most important among all the microphysical processes. It can change the whole structure of cloud system.
微物理过程对对流系统发展和维持有重要作用:强降水的雨滴蒸发过程会加强"冷池"效应,同时增强了雨带南侧原有的地面中尺度辐合线;凝结潜热在低层诱发了与回波相应尺度的中尺度低压,增强了辐合和上升运动,促进对流发展;霰的融化吸热通过冷却大气会不利于气压下降、气流辐合抬升等过程,降低对流不稳定能量,减缓对流发展;重力拖曳使气块冷却降温,降低对流不稳定能量,并且使低层的气压升高、气流辐散,在近地面附近产生出流,加强地面中尺度辐合线的强度。

In the initial stage, the convergence of the low layer was stronger than that of the upper layer of the boundary layer, and the rotation of the boundary layer flow was weak, so a convergence line of the boundary layer was one of important factors to trigger convection.
MCS初期边界层低层的辐合强于边界层高层辐合,边界层气流旋转作用较弱,边界层辐合线是对流触发的重要因素之一。

The flow field construct of meso-β cloud clusters which bring the heavy-hard rainfall in northeast plateau is that the low level cloud cluster is located in the south of converging region, the southern low level influx converged in the cloud cluster and have some affection on the setting up of the rainstorm in the low level. In the middle level, the cloud cluster is lied in near the westerly trough and the southwest airflow ahead of the trough constantly transmits water vapor to the cloud cluster. In the high level, there are a pair of high and low pressure centers around cloud clusters and are obvious divergence airflow, and there is weak ageostrophic high level outflux along pressure force.

The severe storms on the squall line had large radar reflectivity and high tops of echoes. There was a divergence at lower level, a convergence at middle level, and a divergence at upper level in the velocity cross section of the squall. The VIL (Vertical Integrated Liquid water) of the storms increased rapidly to a large value, which is a good indictor of hailstorm. When the probability of severe hail is larger than 30% according to the hail index products, a hail storm is very likely to happen. The convergence line in the boundary can trigger and intensify convections.

In order to develop and modify Gregory scheme for cumulus convective parameterization,we make the improvement as follows:(1) The large-scale moisture convergence is taken into account and the organized inflow,which occurs in the area of large-scale moisture convergence and is directly proportional to it, is added to turbulent airflow.(2) The influence on saturation vapor pressure exerted by supercooled water is taken into account and the initial mass flux is adjusted. Based on diagnosis of the air heating and moistening, the downdraft airflow is adjusted.(3) Based on the character of our country heavy rainfall,which usually occurs in the mixed cloud consisted of stratocumulus and cumulus, the process of excessive convection is restrained by organized outflow in the top of cloud and improving downdraft current and by reducing the evaporation of rainfall and release of latent heat.
