TRANSPORT CHARACTERISTICS IN THE TROPOSPHERE AND LOWER STRATOSPHERE OF THE SOUTHERN HEMISPHERE
Trajectory analyses of air parcels for the Southern Hemisphere spring are performed with observed data during the period from September to December of 1982. It is found that the diffusivity at 60°S and poleward in the lower stractosphere is low during early spring. The diffusion in December is nearl...
