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
