摘要
利用常规气象探测资料、NCEP再分析资料等气象数据资料,分析了2020年8月11—14日新疆地区1次大范围雷暴天气过程。结果显示:此次新疆雷暴天气发生前,500 hPa大气环流形势特点属于“2槽1脊”型。冷涡中的空气柱呈现“低层暖,高层冷”的状态,冷涡后部持续有冷空气南下,加之冷涡移动较慢,受高空冷涡的影响,新疆大多数区域产生了雷暴天气。
A large-scale thunderstorm weather process in Xinjiang from August 11 to 14,2020 was analyzed using conventional meteorological observation data,NCEP reanalysis data,and other meteorological data.The results show that before the occurrence of this thunderstorm in Xinjiang,the situation of 500 hPa Atmospheric circulation was characterized by“two troughs and one ridge”.The air column in the cold vortex presents a state of“warm in the lower layer and cold in the upper layer”.Cold air continues to move southward behind the cold vortex,and the cold vortex moves slowly.Affected by the high-altitude cold vortex,thunderstorm weather has occurred in most areas of Xinjiang.
