摘　　要：利用高低空各种气象资料,采用天气学分析方法,分析和总结了2020年10月13—14日出现在果洛地区的一次寒潮天气过程。结果表明:此次影响果洛地区寒潮过程是新疆槽东移南压型,500 hPa低槽引导地面冷空气不断下滑至33°N附近,地面冷高压沿西北路径南下,将寒潮关键区的冷空气不断输送至果洛东部地区,高低空配合共同导致了此次寒潮天气过程。Using various meteorological data at high and low altitudes and using synoptic analysis methods,this paper analyzes and summarizes a cold wave weather process that occurred in Guoluo area from October 13 to 14,2020.The results show that the cold wave process affecting the Guoluo area was the Xinjiang trough moving eastward and southward pressure type.The 500 hPa low trough guides the ground cold air to continuously decline to near 33°N,and the ground cold high pressure moves southward along the northwest path,continuously transporting the cold air in the key areas of the cold wave to the eastern part of Guoluo.The combination of high and low air leads to the cold wave weather process.
