Title: Northern Hemisphere wintertime variability in a two-level general circulation model. Part II. The maintenance of short and long time-scale disturbances

Journal Article · · J. Atmos. Sci.; (United States)

The energetics of large-scale disturbances of the wintertime, Northern Hemisphere circulation are studied with the OSU two-level general circulation model. The behavior of simulated eddies with short time-scale (2.5 to 10 days) is found to be consistent with observations and with baroclinic instability theory. Eddies with long time-scales (>10 days) appear to be maintained primarily by high-latitude baroclinic energy conversions. Energy conversions characteristic of barotropic processes are found at jet stream latitudes.
