Changing Flow Patterns and Successive Bifurcations
Out of Sections 4.2 through 4.4 emerges a certain view of midlatitude atmospheric circulation. It is dominated by essentially axisymmetric, zonal flow — the prevailing westerlies. They represent the climatological mean of daily flow patterns. The zonal mean flow is baroclinically unstable, and cyclone waves grow on it, reaching finite amplitude and then decaying, to be replaced by new growth of instabilities.
