Maintenance and development of the Ural high and its contribution to severe cold wave activities in winter 2020/21
摘要
Abstract
2020年底至2021年初,连续两次强寒潮入侵中国东部地区,导致大范围强降温.本文研究这两次寒潮的特征和形成机理.主要结果如下:从2020年12月中旬到2021年1月中旬,乌拉尔山地区维持一宽阔的高压脊.脊前北风的维持和加强导致局地斜压性增加,导致下游横槽槽底等高线梯度加大,冷平流加强,西伯利亚高压加强和向南扩张.准定常波能量传播是乌拉尔山阻塞发展和持续的主要原因.关键词
