Abstract

For all days of 1948-2017 the 10-day backward trajectories of air particles arriving in the convective (mixed) layer of the atmosphere over Moscow were calculated using the NOAA HYSPLIT_4 trajectory model and NCAE/NCAR Reanalysis. A total of 75000 backward trajectories were calculated. By the daily precipitation data of the Roshydromet weather station VDNKh (Moscow, Russia) the fields of the average contribution of potential sources to precipitation in Moscow were reconstructed for the warm (April-September) and the cold (October-March) seasons of the year using the PWT (precipitation weighted trajectory) method. Regions that contribute to different precipitation in Moscow in the warm and cold seasons were identified by the fields obtained. An attempt was made to reconstruct the field of the absolute contribution of the potential source to the total precipitation in Moscow in 1948-2017 in the cold and warm seasons.
