Plots

Notes from Frédéric: (9/Feb)

I just spoke to a colleague of mine teaching statistics. He told me that our second year students that will attend the workshop will have knowledge in PCA and clustering methods via ascending hierarchical classification (with R)

So I think that on Day 2, it would be nice to make them do the PCA for ECMWF t+96 ensemble forecasts (20120920 analysis and forecast for the 20120924, figure 5 of Pantillon), the ascending classification (figure 6) and the clustering (figure 7). We could leave the classification and the clustering as extra questions, to leave room for the stochastic ensemble, the EDA and the class ensemble.

If you want (and if PCA, classification and clustering are difficult to do in Metview) I can see with my colleagues how to do that in R. I will just need the ECMWF data. What do you think ?

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?
