mio::WinstralListonAlgorithm Class Reference

Detailed Description

DEM-based wind-exposure interpolation algorithm, for a spatially explicit varying DW field.

This is an implementation of the method described in Winstral, Elder, & Davis, "Spatial snow modeling of wind-redistributed snow using terrain-based parameters", 2002, Journal of Hydrometeorology, 3(5), 524-538. The wind direction for determining wind-exposure is taken from a 2D wind direction field. The DEM is used to compute wind exposure factors that are used to alter the precipitation fields. It is usually a good idea to provide a DEM that also contain the accumulated snow height in order to get a progressive softening of the terrain features.

It takes the following arguments:

  • BASE:: provide the base algorithm to pre-fill the grid, since this method must first use another algorithm to generate an initial precipitation field, and then modify it. By default, this base method is "idw_lapse" and switches to "avg" if only one station can provide the precipitation at a given time step (for an easy fallback). Please do not forget to provide any necessary arguments for this base method!
  • DMAX: maximum search distance or radius (default: 300m);
Remarks
  • Only cells with an air temperature below freezing participate in the redistribution
  • Using the WinstralListonAlgorithm also requires the specification of an interpolation method for DW
