Key Parameters
- Height of PV=1 PVU:
In the field of the pressure height of PV=1 PVU a long narrow elongated zone of heights of about 400 hPa is visible, associated with a dark stripe in the WV imagery. - 500 hPa geopotential height:
The distribution of geopotential height often shows a large trough, the trough axis coincident with the highest values of PV. However, the PV field gives a better overview of smaller scale features (see Additional Parameters Indicative Of The Diagnosis Of Cloudiness: Potential Vorticity
