摘　　要：利用常规天气资料和数值预报产品,应用天气分析和诊断分析方法,对2020年2月14—16日发生在三门峡市的一次寒潮天气过程的环流背景与影响系统进行综合分析。结果表明:此次寒潮天气过程主要是由地面冷高压和500 hPa上贝加尔湖以北的冷涡引导较强冷空气南下造成的。EC数值预报的高度场、温度场、气压场对此次寒潮天气过程都表现出较好的预报能力。结合此次寒潮过程的服务情况,可以为今后做好三门峡市寒潮等灾害性天气过程的预报预警服务提供参考。Based on conventional weather data and numerical forecast products,applied weather analysis and diagnostic analysis methods to comprehensively analyze the circulation background and impact system of a cold wave weather process that occurred in Sanmenxia City from February 14 to 16,2020.The results showed that the cold wave weather process was mainly caused by the surface cold high and the cold vortex in the north of Baikal Lake at 500hPa leading the strong cold air to the south.The height field,temperature field and pressure field of the EC numerical forecast show good prediction ability for this cold wave weather process.Combined with the service situation of this cold wave process,it can provide some reference for the prediction and early warning service of the cold wave and other disastrous weather processes in Sanmenxia City in the future.
