Abstract

The peculiarities of the troposphere and stratosphere dynamic processes that accompanied cooling events (cold waves) with a duration of more than a week in the northwest of European Russia (on the example of St. Petersburg) and in its north and center (on the example of Moscow) in early and late December 2021, respectively, are analyzed using reanalysis data, station observations, and trajectory modeling. In both cases the daily temperatures dropped below −10°C, and cold waves were accompanied by the air mass transport from the northeast

有助于 2021 年 12 月在欧洲俄罗斯西北部和中部形成寒潮的对流层和平流层环流条件分析

摘要利用再分析数据、观测站观测数据和轨迹建模，分析了 2021 年 12 月初和 12 月末分别在欧洲俄罗斯西北部（以圣彼得堡为例）及其北部和中部（以莫斯科为例）伴随持续时间超过一周的降温事件（寒潮）的对流层和平流层动态过程的特殊性。在这两种情况下，日气温都降到了-10°C 以下，寒潮伴随着来自东北部的气团输送。
