The Wintertime Southern Hemisphere Split Jet: Structure, Variability, and Evolution.

Presents a study that examined the structure and evolution of the winter season Southern Hemisphere split jet. Details on the development of a split-flow index (SFI) to quantify the magnitude of the split flow; Use of the SFI in the examination of the variability of the split jet on interseasonal and interannual time scales; Discussion on the climatology and synoptic setting of split-flow and non-split-flow regimes.
