class Winstral
Compute the Winstral parameter that can be used to redistribute wind and precipitation in complex terrain to improve simulation of snow cover variability.
Depends:
Direction at reference height ‘vw_dir’ [degrees]
Snow depth [m] (optional)
Provides:
Winstral parameter “Sx” [degrees]
Configuration:
{ "dmax": 300, "size_of_step": 10.0, "height_param": 0.0, "angular_window": 30.0, "delta_angle" : 5.0, "incl_veg": false, "incl_snw": false "use_subgridz": true }
- dmax
Max distance to search
- size_of_step
Size of the step to take when searching
- height_param
Height parameter to account for instrument height or the impact of small terrain perturbation on Sx . See Winstral et al. (2013) for more details
- angular_window
The angle for which to bin the wind directions in
- delta_angle
- incl_veg
Should vegetation height be added to terrain height for the calculation
- incl_snw
Should snow height be added to terrain height for the calculation
- use_subgridz
Use an interpolated height within the triangle instead of just the triangle cell centre. Avoids step function results.
