Additional Experiment - Nudging to Specifiy Dynamics

The following experiments are suggested for interested groups. These investigate the role of feedbacks in maintaining the QBO. The general idea would be to alter model physics or numerics while maintaining the zonal mean state. This technique will isolate the resolved wave response without feedbacks from the changing zonal men state. Possible experiments might include:

  • nudging zonal-mean conditions in the tropical stratosphere
  • nudging aspects of the tropical troposphere
A first draft for this experiment  is being prepared by Kevin Hamilton and will appear here shortly. At this time wider discussion will be encouraged to best facilitate wider participation within the group.
