Attendees
Students from ENM only - no other OpenIFS users this time.
...
Work in groups: 5 x 4 persons, 2 per PC.
Facilities
PC running CentOS (based on redhat enterprise)
Language
Students have asked for more lessons in English.
English teachers will be there. Encourage students to write and speak in English.
? tutorials written in English? (maybe with some parts in French)?
Topic
Storm Nadine. Case of extratropic transition & severe weather over France.
...
Sensitivity - two main issues : Model resolution - to model interaction of the storm and cut-off low; Convection processes.
Could focus on clustering of the ensemble ? Different algorithms for clustering?
Tubing .v. clustering. see: http://journals.ametsoc.org/doi/abs/10.1175/1520-0434%281999%29014%3C0741%3ATAATCF%3E2.0.CO%3B2 Ask Linus about this.
TODO
- Decide on forecasts for workshop: resolution, start date(s) and forecast length
- Run HRES & ensemble forecasts
- Book accommodation
- Check for observations we might have in the archive for HYMEX that could be used
...
Forecasts
T1279 HRES
Ensemble
Plots
PCA in Metview - speak to Linus (he says he has some Fortran code). Or could use R
Try to reproduce the plots in the article.
Day 1/2 plots
HRES & analysis only (ensemble in later task).
Plots that summarize the situation, focused on the study of Nadine and the cutoff (horizontal maps and vertical cross sections) and maybe a plot of the rainfall over France.
Notes from Frédéric: (9/Feb)
...
I will also think about the interesting plots that we could do to illustrate this case, for example vertical crosssection of potential vorticity.
Notes
SCM exercises - sensitvity of the model to changing physics. Focus on convection, initiation of deep convection. Stochastic physics, impact on convection? impact of convective scheme?
...
- how to weight extreme events in the ensemble?
- what's the best way of doing ensembles if dont' want to miss extremes?
Travel & local arrangements
ENM is approx 20mins by car from the airport.
