Yes, the model uses the topography from the meteorological data. If that is not available it will use the topography data located under the bdyfiles directory (TERRAIN.ASC)

I use WRF model data.
How can use the TERRAIN.ASC file for topography?

If you are using WRF then HYSPLIT will use the terrain that WRF has.
HYSPLIT runs on a following terrain sigma coordinate, so whatever WRF provides is what HYSPLIT will use.
