        城市冠层热动力过程对雷暴活动的影响研究:观测证据和模拟验证

        杨元建 (Nanjing University of Information Science & Technology)

        9 pm (GMT+8), 21th Jun, Saturday

        Abstract:

        雷电灾害已被联合国有关部门列为“最严重的十种自然灾害之一”,研究城市雷电活动特征及其形成机制能够为防灾减灾提供重要科学支撑。基于地面气象观测数据(AWS),北京市已建成300多个自动站,城市局地气候分区数据(LCZ),雷达、探空、风廓线、再分析等数据,结合数值天气预报模式和CFD技术,揭示了超大城市(北京市)雷电活动特征,发现了空气污染和热力过程对雷电活动的影响规律,阐明了动力过程对雷电活动的影响机制,诊断了城市地闪活动及雷暴演变机制。
