| 1. | The first assumption will be an initial potential vorticity anomaly somewhere in the upper troposphere.
|
| 2. | An equatorward heat flux is induced, decreasing potential vorticity and pressure anomalies and yielding cyclolysis.
|
| 3. | They found that changes in potential vorticity at the tropopause can cause changes in the wind field.
|
| 4. | Specifically, different schemes have different methods of parametrizing the potential vorticity which results in different tracks.
|
| 5. | The deviations are caused by the Coriolis force and conservation of potential vorticity which leads to changes of relative vorticity.
|
| 6. | The tropopause lowers the further towards the pole you go in general and you have higher stratospheric potential vorticity poleward.
|
| 7. | The potential vorticity is absolute vorticity divided by the vertical spacing between levels of constant entropy ( or potential temperature ).
|
| 8. | Atmospheric Rossby waves are the result of conservation of potential vorticity and are influenced by the Coriolis force and pressure gradient.
|
| 9. | Such upper-level positive potential vorticity will induce a flow non-local to where the potential vorticity anomaly is.
|
| 10. | Such upper-level positive potential vorticity will induce a flow non-local to where the potential vorticity anomaly is.
