Presentation Transcript

  1. WRF Preprocessing System(WPS)

  2. Purpose of the WPS • Prepares input to ARW for real-data simulations • Defines simulation domain and nested domains. • computes latigude, longitude, map scale factors, Coriolis parameters for ever grid point. • Interpolates time-invariant terrestrial data to simulation grids (e.g. terrain height and soil type). • Interpolates time-varying meteorological fields from another model onto simulation domains.

  3. Data Sources and Programs

  5. WPS Programs • geogrid • Define size/location of model domains and interpolate static terrestrial fields to simulation grids. • ungrib • Extract meteorological fields from GriB files. • 'Vtables' are used to select which variables are used from each model GriB file. You can copy and modify these files for your own GriB data sets. • metgrid • Horizontally interpolate meteorological fields to simulation grids.
