[Wrf-users] pressure at surface lower than at level 1

[CARLOS ROMÁN CASCÓN]

Hi,

I have obtained the attached plot of PSFC (surface pressure, black line)
and PTOT (total pressure at level 1, red line).

As you can see, there are some times when the pressure at surface is
lower than at level 1.

I think this does not make sense... even when I am trying to study a
possible gravity wave over the zone.

Can anyone suggest me something? (why I see these oscillations in P at
the surface but not in lev 1?)

Thank you very much in advance.

Regards
