Key research areas and corresponding objectives

Part of an initiative for the improved representation of GWs in atmospheric models should be as complete a diagnosis as possible of the time and space dependence of the spectral GW field. Next one can ask oneself what brings this dependence about. Having obtained this understanding, and having cast it into a model as realistic as possible, one can address GW effects. These steps are interwoven, however: Models must be used for integrating selective and imperfect measurements into a consistent GW field in space and time, and these already rely on some effective description of GW effects. With this in mind, three interrelated and partially overlapping key research areas are defined:

  1. The spatial, temporal and spectral distribution of the atmospheric GW field.
  2. The processes explaining and controlling this GW distribution.
  3. The impact of GWs on weather and climate.
