[Wrf-users] Can somebody tell me why?

Hello,

The Vtable.AVN(I used) has these lines:
  11 | 100  |   *  |      | T        | K       | Temperature
  33 | 100  |   *  |      | U        | m s-1   | U
  34 | 100  |   *  |      | V        | m s-1   | V
  52 | 100  |   *  |      | RH       | %       | Relative Humidity
   7 | 100  |   *  |      | HGT      | m       | Height
and
  11 | 105  |   2  |      | T        | K       | Temperature       at 2
m
  52 | 105  |   2  |      | RH       | %       | Relative Humidity at 2
m
  33 | 105  |  10  |      | U        | m s-1   | U                 at 10
m
  34 | 105  |  10  |      | V        | m s-1   | V                 at 10
m
   7 |   1  |   0  |      | HGT      | m       | Terrain Heights

Code src/grib_prep/util/parse_table.F removes these duplicates and 
prints out the following message in the run time:
 Duplicate name.  Removing T         from output list.
 Duplicate name.  Removing U         from output list.
 Duplicate name.  Removing V         from output list.
 Duplicate name.  Removing RH        from output list.
 Duplicate name.  Removing HGT       from output list.

Why does the Vtable have these un-necessary duplicates if the WRFSI does
not extract these variables from grib data? Then, from where does the
WRFSI 
extract the data for its lower boundary condition?
