On the basis of the calculated Laplacians of the geopotential 1000hPa, the features of the spatial and temporal distribution of vertical current fields at the surface of the earth in the northern hemisphere over the Atlantic-European sector, limited by longitudes of 90o w.l. – 90o e.l., in different seasons of the year and revealed their temporal dynamics. Greater temporal stability of the spatial position of the elements of vertical air movement is noted. Their directionality remains unchanged in different seasons of the year, with a slight change in flow intensity over time. It was revealed that the intensity of vertical streams in high latitudes is 1,5–2 times higher than in low latitudes.
