Abstract	The structure of the large-scale background magnetic field evolves in time and space. The large-scale horizontal transport velocity field of the magnetic flux patterns was inferred over the whole solar photosphere in the course of two solar activity cycles from year 1976 to 1999. The method of velocity determination and the testing procedures of the velocity accuracy are presented. The non-axially symmetric component of the horizontal velocity was found and both zonal and meridional velocity regions were described. The horizontal large-scale transport velocity regions vary in shape and the intensity during different phases of the 11-year solar activity cycle. The total horizontal transport velocity is characterized by the presence of variable amounts of the vector field vortices with symmetric orientation relative to the solar equator. The zonal velocity regions, distributed inside of the zonal belt limited by latitudes ± 35°, are persistent for about 4 Carrington rotations. Recurrent structures of similar velocity distributions are not coherent over the whole solar photosphere.
