Sequence of PV for Wave A: 2nd July 2004:00 UTC - 3rd July 2004:00UTC

2nd July 2004: 00UTC
The vertical cross sections on PV in the sequence shown in the window beside are drawn in such way that they cover the area immediately south of the wave bulge and the area which is darkest in the WV image.

The height of PV = 1 unit is rather low namely 500 hPa . In this wave it is even somewhat lower in the beginning phase but later rises to about 500 hPa.

The VCS was laid from position A to B.
