[en] The possible relation of a major sudden stratospheric warming (SSW) with the mid-latitude surface weather conditions was investigated using data from the ERA-Interim and NCEP–NCAR reanalyzes. An important feature of the SSW event is the impact on lower altitudes, when temperature and wind anomalies descend downward into the high- and mid-latitude troposphere during the weeks or even month and influence the surface weather [1, 2]. Owing to known SSW impacts on the surface weather [2], we consider the possible relation of the SSW event in winter 2018 to cold weather anomaly in the Northern Ukraine and North-East China in February 2018.
