Summary Making use of a 500 mb numerical forecast some problems of atmospheric large-scale diffusion are investigated. The expansion of various sets of clusters of particles is compared with the predictions based on the similarity theory of homogeneous turbulence. The spreading rates were in the beginning of the period of the forecast in a good agreement with the theoretical prediction, but later on they fell to the values considerable smaller than the predicted ones. The reasons of such behaviour are discussed. Furthermore the difference in zonal and meridional expansion of the clusters is demonstrated, the zonal expansion rates being more than one order of magnitude greater than the meridional ones.
