class MS_wind : public module_base
Calculates windspeeds using the Mason Sykes wind speed from Essery, et al (1999), using 8 lookup map from DBSM. Optionally uses Ryan, et al. for wind direction correction.
Depends from met:
Wind at reference height “U_R” [ \( m \cdot s^{-1}\) ]
Direction at reference height “vw_dir” [degrees]
Provides:
Wind speed at reference height “U_R” [ \( m \cdot s^{-1}\) ]
Wind direction ‘vw_dir’ at reference height [degrees]
Speedup magnitude “W_speedup” [-]
Zonal u speed component at 2m “2m_zonal_u” [ \( m \cdot s^{-1}\) ]
Zonal v speed component at 2m “2m_zonal_v” [ \( m \cdot s^{-1}\) ]
Original interpolated wind direction “vw_dir_orig” [degrees]
Parameters:
Requires speedup, u, and v parameters named “MS%i_U” and “MS%i_V” and “MS%i” for each of the 8 directions. These need to be generated using DBSM in
tools/MSwind.Configuration:
{ "speedup_height": 2.0, "use_ryan_dir", false }
- speedup_height
The height at which the MS Wind tool was run for. The default is 2 m and shouldn’t be changed.
- use_ryan_dir
Instead of using the _u and _v components to compute direction perturbation, use the algorithm of Ryan as per Liston and Elder (2006)
