LC for statistical and dynamical adaptation

• Issues at the final discussion of the workshop
• Statistical adaptation of more than one variable,
  for more than one location, and more than one
  time can produce physical inconsistencies.
• Was not considered a significant problem.

4
LC for statistical and dynamical adaptation

• Issues at the final discussion of the workshop
• Is a change of adaptation methods required by the
  continuous progress of NWP towards higher
  resolution models (1-km scale)?
• Necessity of downscaling will persist.

5
LC for statistical and dynamical adaptation

• Issues at the final discussion of the workshop
• Statistical adaptation producing probabilistic
  forecasts vs. EPS. Competition, benchmark,
  synergy?
• Lack of, and need for, comparison studies.

6
LC for statistical and dynamical adaptation

• Issues at the final discussion of the workshop
• There is a highly diverse spectrum of theoretical
  and algorithmic approaches to NWP adaptation and
  post-processing. More coordination needed?
• No, there ist little actual redundancy.
  Continuing exhange of findings (papers,
  workshops) is however essential.

7
LC for statistical and dynamical adaptation

• Issues at the final discussion of the workshop
• Format of the workshop.
• No changes required. More presentations of
  downstream applications (road forecasts, air
  pollution forecasts) would be interesting.
• Next workshop June 2007.
