Using ground station observation data, ERA5 reanalysis data, and GPCP global precipitation data, this paper takes the regional heavy rainstorm caused by the coupling of the Qinghai–Xizang Plateau vortex and the Southwest China vortex on June 4–7, 2019, as an example to diagnose and analyze the coupling characteristics and formation mechanism of precipitation. The results show that (1) the weather process was caused by the combined action of the Qinghai–Xizang Plateau vortex and the Southwest China vortex, and the precipitation developed explosively from night to early morning. On June 4, the two vortices produced precipitation centers in the northwest and southwest, respectively, and the precipitation was located in the rear of the Qinghai–Xizang Plateau vortex and the center of the Southwest China vortex. The two vortices were coupled in the early morning of June 5–6, and the precipitation shifted to the front of the vortex, strengthening to its peak. The center of the heavy rainstorm was north of Hubei Province. On the night of 6, the two vortices moved eastward toward the sea, and the precipitation area disappeared on land. (2) During the evolution of the two vortices, when the plateau vortex moved eastward from the plateau, the divergence term and the vertical transport term enhanced the positive vorticity of the basin. At the same time, as the low-level convergence configuration strengthened, the southwest vortex was further induced to develop in the basin, and precipitation occurred in both vortex regions, providing a key dynamic condition for the subsequent coupling of heavy rain. (3) During the coupling development, the centers of the two cyclones at different heights merged to form a deep convective system, which generated strong positive vorticity columns and strong convective instability, accompanied by vertical upward motion and secondary circulation development. The southwest monsoon and the southerly airflow outside the subtropical high transported abundant water vapor to the front of the vortex, and under the synergistic effect of deep shear convergence and strong dynamic uplift, this process eventually led to heavy rain.

本文基于地面站观测数据、ERA5再分析资料和GPCP全球降水资料,诊断分析了2019年6月4~7日的高原涡与西南涡耦合引发区域性大暴雨过程。结果表明:(1)此次天气过程是由高原涡与西南涡共同作用引发,降水在夜间至凌晨有爆发性发展。6月4日两涡各自在西北和西南地区产生降水,且降水在低涡中心及后部;5~6日凌晨两涡耦合,降水移至低涡前部加强并达到峰值,大暴雨中心在湖北北部;6日夜间两涡东移出海,降水区在陆地上消失。(2)两涡演变过程中,发现高原涡东移出高原时,散度项和垂直输送项增强了盆地的正涡度,同时伴随低空辐合配置显著加强,诱导西南涡在盆地生成,两涡区域随之出现降水,并为后续耦合大暴雨提供了关键的动力条件。(3)在耦合发展时,两涡不同高度的气旋中心合并形成深厚对流系统,激发出强正涡度柱和强对流不稳定,并伴随垂直上升运动和次级环流发展。西南季风和副高外围的偏南气流向低涡前部输送充沛的水汽,在深厚的切变辐合和强动力抬升协同作用下,最终导致大暴雨发生。
