Both theory and practice analysis illustrate that stronger divergence field results from uneven distributed horizontal wind field on the right when high level current axis slopes. Owing to convectional wind convergence at low level responds to high level divergence and leads to storm.
理论和实际分析均表明:高空急流轴一旦发生倾斜,则由于其出口区水平风场的分布不均匀势必会在倾斜急流轴出口区的右侧产生较强的辐散场,由于对流风的作用,低层辐合必然会对高层辐散产生响应,诱发暴雨发生。

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。

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.
产生高原东北部地区大到暴雨天气过程的中—β尺度云团的流场结构特征是:在低层,云团位于辐合区的南部,低层的偏南低空入流在云团内辐合,对大到暴雨的形成有一定的作用;在中层,云团位于西风带低槽附近,槽前的西南气流不断地给云团输送水汽;在高层,云团附近有一对高、低压中心,为明显的辐散气流,沿气压梯度力方向有强度不强的非地转高空出流。

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.
