class Liston_wind : public module_base
Calculates windspeeds using a terrain curvature following Liston and Elder 2006. Direction convention is (North = 0, clockwise from North)
Depends from met:
Wind at reference height “U_R” [ \(m \cdot s^{-1}\)]
Direction at reference height ‘vw_dir’ [degrees] (North = 0, clockwise from North)
Provides:
Wind at reference height “U_R”
Interpolated wind field at reference height prior to downscaling “U_R_orig” [ \(m \cdot s^{-1}\)]
Wind direction “vw_dir” [degrees]
Original wind direction “vw_dir_orig” [degrees]
Amount the wind vector direction has been changed “vw_dir_divergence” [degrees]
Zonal U at reference height “zonal_u” [ \( m \cdot s^{-1}\) ]
Zonal V at reference height “zonal_v” [ \( m \cdot s^{-1}\) ]
Configuration:
{ "distance": 300, "Ww_coeff: 1, "ys": 0.5, "yc": 0.5 }
- distance
Distance to “look” to compute the terrain curvature.
- Ww_coeff
Leading coefficient in equation 16. Used for compatibility with calibration approach such as done by Pohl.
- ys
Slope weight. Valid range [0,1]. The value of 0.5 gives equal weight to slope and curvature
- yc
Curvature weight. Valid range [0,1]. The value of 0.5 gives equal weight to slope and curvature
