摘　　要：本文利用NCEP/NCAR再分析资料、MICAPS常规观测资料、自动站资料以及气象报文资料对2016年5月12日绵阳机场一次雷暴空报过程进行诊断分析,结果表明:(1)此次天气过程从地面到高层系统叠加较好,但是大气中水汽、能量及动力条件配合不好,导致12日雷暴天气过程出现了空报。(2)此次天气过程中大风产生的原因为冷平流较强,机场上空整层为下沉运动,动量下传,地面具有强气压梯度。(3)大风指数对大风预报具有一定指示意义。(4)影响系统移动速度判断不准是空报的另一原因。Analyses of a false thunderstorm process on May 12,2016 at Mianyang Airport by using NCEP/NCAR reanalysis data,MICAPS conventional meteorological observations, automatic meteorological station and meteorological message, the results show that ：（1）The weather process from the ground to the high-level system overlay better, but the atmosphere of water vapor, energy and dynamic conditions are not good, leading to the 12th thunderstorm weather appeared empty re- port.（2）The reason for the strong wind is that there is a strong cold advection, atmospheric subsidence movement over the airport, the momentum is transmitted downward ,the ground has a strong pressure gradient.（3）The strong wind index has certain instruction significance to the strong wind fore- cast.（4）Affect system＇s movement speed misjudge is empty another reason..
