Abstract The upper-level circulation of the Southern Hemisphere winter is characterized by two distinct zonal wind maxima: a subtropical jet found in the vicinity of Australia and the western Pacific Ocean, and a polar jet which maximizes in the Indian Ocean in the 45°–55°S latitudinal belt. This paper describes the global characteristics of the atmosphere for cases with strong subtropical jets during the 1979 Northern Hemisphere summer. Such cases are shown to co-exist with episodes of strong release of latent heat in the Northern Hemisphere at similar longitudes. Gridded analyses of the Global Weather Experiment produced by the Geophysical Fluid Dynamics Laboratory of the National Oceanic and Atmospheric Administration are used to obtain composites of atmospheric motions prior to the onset and during active episodes of the Asian Monsoon. Projections of these motions into the normal modes of a linearized primitive equation model about a basic state at rest are presented to isolate observed global flow ch...
