Abstract

A joint analysis of 10% of the lowest daily surface air temperatures (SAT) in Moscow in June 1971-2016 and corresponding 5-day backward trajectories of elementary air particles calculated using NOAA HYSPLIT_4 trajectory model was carried out. The most probable paths of cold outbreaks to Moscow have been revealed by the cluster analysis. The weighted trajectory method was used to localize the regions where the air masses bringing 10% of the lowest SAT anomalies in Moscow in June were transported from. The structure of large-scale atmospheric circulation associated with cold air outbreaks is revealed.
