Hi AF,
As a function doesn't exist to extract the seasonal cycle out of a 2-D
array, you can code it yourself:
arr_sc = arr(:11,:) ; set up array to store seasonal cycle. arr is
dimensioned time x lon. time starts in January
arr_sc = arr_sc@_FillValue ; just in case, set arr_sc to _FillValue
do gg = 0,11
      arr_sc(gg,:) = (/ dim_avg_n(arr(gg::12,:),0) /) ; for gg = 0,
grab all January's, and average.
end do
delete(arr)

dim_avg_n documentation:
http://www.ncl.ucar.edu/Document/Functions/Built-in/dim_avg_n.shtml

If you are not familiar with the subscripting used in the coding above,
see the NCL reference manual here:
http://www.ncl.ucar.edu/Document/Manuals/Ref_Manual/NclVariables.shtml#StandardSubscripts

Hope that helps. If not, please respond to ncl-talk.
