• The GWDO (Gravity Wave Drag by Orography)
  parameterization is available in the WRF model
  from the version 3.1.
• The gravity waves are subgrid scale processes. -gt
  The Gravity waves produce synoptic scale body
  forces when they break (the gravity wave drag).
  -gt The traditional problem of the simulated
  climate, the cold pole problem, is reduced when
  the GWD is considered. -gt The Gravity Wave Drag
  parameterizations are needed.
• In this study, the evaluation of the GWDO
  parameterization and investigation of its impact
  on the simulated climatology are conducted using
  the global WRF model.
