摘  要:
本文使用观测资料、雷达资料和数值模式资料,对 2022 年 6 月 13 日午后至夜间的冷涡背景下的两次影响济南的强对流过程进行分析.结果表明,地面辐合线与冷池的复杂相互作用在对流回波发展加强过程中起到了重要的作用,尤其是造成了第一次对流降水强度强、移动迅速,发展为超级单体和弓形回波.根据环境参数的实况分析和模式预报,可以较准确地判断 2 次对流过程的强度.环境条件较弱是造成第二次对流未发展加强的主要原因.在临近预报业务中,预报员需要利用多种实时加密观测数据,结合对流发展条件和中尺度模式预测对流天气的发生发展情况.

摘  要:
Using observational data,radar data,and numerical model data,this paper analyzed two strong convective processes affecting Jinan under the background of a cold vortex from the afternoon to the night of June 13,2022.The results showed that the complex interaction between the ground convergence line and the cold pool played an important role in development and strengthening of the convective echoes,especially in causing strong intensity and rapid movement of the first convective precipitation,which led to the development of supercell and bow shaped echoes.Based on the factual analysis of environmental parameters and model predictions,the intensity of two convective processes could be accurately determined.The weak environmental conditions were the main reason for the lack of development and strengthening of the second convection.In the nowcasting business,forecasters need to use various real-time encrypted observation data,combine with convective development conditions and mesoscale models to predict the occurrence and development of convective weather.
