The ozone fluxes and flux convergences within the region between 30 and 0.4 mbar for the Northern Hemisphere are investigated for the period January 1 to March 31, 1979, using Nimbus 7 solar back-scatter ultraviolet ozone profiles and the meteorological data derived from NOAA satellites. The results indicate that large contributions to the ozone transport and the transport convergence are due to mean vertical advection and horizontal eddy processes. The contribution from the vertical eddies is insignificant. The transport of ozone into the polar latitudes during winter and early spring is mainly accomplished by the large-scale horizontal eddies. The results also show that more ozone is transported into the polar region by the large-scale eddies on disturbed days than on quiet days.
