Relative Humidity:
The field of relative humidity shows a maximum in low (750 hPa) and an another one in high levels (500 hPa). But as usual,
the resolution of the ECMWF model can not resolve the single cells of an EC.
Divergence:
In this case the field of divergence shows only very weak maxima of convergence. This is not so typical for a well developed
EC case.
PVA:
The maximum of PVA at 400 hPa fits very well to the single cloud cells of the EC. This parameter is in accordance with the
ideal situation of an EC.
Vertical Motion (Omega):
There is some upward motion, but compared to divergence and PVA, it seems to be more related to PVA than to divergence.
