[Wrf-users] Registry and staggered variables

[Maxime Colin]

Hi all,


Here is a quick question about variables which would naturally staggered but in fact are not staggered because the variable doesn't depend on some coordinates.


To be very practical, I have added a vertical profile of U-wind in WRF code, in order to create a manual nudging. This target vertical profile of U (called U_target_prof) only depends on z. But as it is applied on U variable in the code, it seems relatively natural to consider it as staggered along the x-axis. But does it actually make any sense to say such a thing?


In the registry (Registry.EM_COMMON), should I define this variable as staggered or unstaggered:

"state    real    U_target_prof         k       dyn_em      1         -      h    "       OR

"state    real    U_target_prof         k       dyn_em      1         X     h    "         ?


Thank you very much for your help.


Maxime.
