Another point of interest is that the jet stream now flows to the south of the surface Low center whereas in the two preceding diagrams the jet ran north of the surface Low. The final stage of occlusion is shown in Figure 5. WebJetstreams are intense, narrow quasi-horizontal currents of wind associated with strong vertical shear and found at or near the tropopause. A jetstream is defined by the following attributes: intense: at least 30 m/s for upper troposphere, at least 15 m/s for lower troposphere. narrow: one-half to one of magnitude less in width than in length.
