Re: A(time,lat,lon)-B(lat,lon)???

Mateus approach will work file.
Another approach:
http://www.ncl.ucar.edu/Document/Functions/Built-in/conform.shtml

  diff = A - conform(A, B, (/1,2/) )

  diff_at_long_name = "Difference" ; meta data
  diff_at_units = A_at_units
  copy_VarCoords(A, diff)
  printVarSummary(diff)
