This is very easy:

 ! this will define seasonal and monthly climatological axes
set dat climatological_axes
! have a look at these:
sho axis month_irreg
list t[gt=month_irreg]

! form the climatology:
let vname_cl = vname[gt=month_irreg@mod]    ! if "vname" is the name  
of your variable

! try plotting this to see what it is doing
plot/x=.../y=.../z=... vname
plot/over/x=.../y=.../z=.../t=1-jan-1997:31-dec-2004 vname_cl    !  
choose the time for your data
