PC running CentOS (based on redhat enterprise) - 64bit (confirmed), 8GB RAM, 30GB free in /tmp

Student accounts limited to 5GB - can we put the VM image to /var/tmp on each PC? . As long as this isn't deleted during the course the students wouldn't lose their work.ftp the VM image to a central server, then copy the image to /var/tmp/ on each PC

28/4: Routing issue on class PCs means we need a VM all the files already installed to provide via ftp.

Paper: Pantillon, F., Chaboureau, J.-P. and Richard, E. (2015), Vortex–vortex interaction between Hurricane Nadine (2012) and an Atlantic cut-off dropping the predictability over the Mediterranean. Q.J.R. Meteorol. Soc.. doi: 10.1002/qj.2635 http://onlinelibrary.wiley.com/doi/10.1002/qj.2635/abstract 


Sensitivity - two main issues : Model resolution - to model interaction of the storm and cut-off low;  Convection processes.

Linus says ensemble is sensitive to SST. This particular case was in fact used as part of the argument for coupling the ocean model (NEMO) from day 1 in the ensemble forecast rather than day 10 as used in 2012; days 1-9 used persisted SST anomalies.

TODO

  •  Decide on forecasts for workshop: resolution, start date(s) and forecast length : all runs start 00UTC 20 Sept 2012
  •  Extract HRES & analysis
  •  Run ensemble forecasts
  •  Book accommodation
  •  Install SCM on OpenIFS VM
  •  Get PCA code from Linus & try it
  •  Get USB sticks from comms
  •  Frédéric to check last year's VM will run on classroom PCs and ensure VirtualBox (or VMware) is installed.
  •  Check for observations we might have in the archive for HYMEX that could be used

Data

Data

nb. limit of student accounts is 5Gb. Unless this can be changed we should aim for 4Gb total size of VM (this will limit no. of datasets, fields & levels)Needs reviewing

Analyses:

T1279 20120918 00Z - 20120925 00Z

Fields / levels (TBD)

MSLP, T2m, 10m winds, total precipitation

Geopotential, temperature, temperature, winds (U/V) @ 250, 500, 850hPa

PV + wind @ 330 K isentrope  ( Frédéric asked for geopotential/winds at 1.5PVU but I don't think we archive these?)

Vertical x-sections

Potential temperature, potential vorticity, winds, humidity, vertical vel. -- needs reviewing, would need all pressure levels & will be too much data?

Operational ensemble 2012Ensemble:

Actual operational ensemble T639TL639. 20120920 00Z - 20120925 00Z (all members)

Fields / levels (TBD)


Ensemble Current operational ensemble (with NEMO on day 1) (expt id: TBD)

Current operational configuration: T639. 20120920 00Z - 20120925 00Z (all members) (Glenn to ask Frederic for the experiment)

As for 2012 operational ensemble.

 Fields / levels (TBD)

Uncertainty runs:

T319L91. No NEMO coupling, wave model off (OpenIFS config)

Do we have time or Suggest we do not have time nor the space on the VM for these.?

(a) EDA/SV/SPPT/SKEB ; - exptid 'gik3'

(b) EDA/SV - exptid TBD

; (c) SPPT/SKEB : Will we do class ensembles ?- exptid TBD


Data domain

Extract data similar to domain in figure 1 but suggest crop 50W - 20E / 30N - 65N (adjust to suitable aspect ratio)

 

Plots

 

Usual plots

- 1x1, 2x2

- Difference maps (an-fc, ens-control)

- stamp maps

- RMSE curves geopotential (500hPa), RMSE plumes

- spaghetti plots


Horizontal / isobaric maps

MSLP + 10m winds / T2m -> interesting for tracking Nadine & primary circulation

Geopotential height + temperature at 500hPa --> large scale patterns, position of Nadine's low and the Atlantic cutoff

Geopotential heigth + temperature at 850hPa --> lower level conditions, detection of fronts

1.5 PVU geopotential + winds or 330K potential vorticity (PV) + winds --> upper level conditions, upper level jet and the cutoff signature in PV


If space is an issue, decide which plots are to be interactive and which are available as images only.

...

I will also think about the interesting plots that we could do to illustrate this case, for example vertical crosssection of potential vorticity.

TODO

  •  Decide on forecasts for workshop: resolution, start date(s) and forecast length : all runs start 00UTC 20 Sept 2012
  •  Decide what to do about provision of satellite imagery (or not - issues iwth licensing)
  •  Extract HRES & analysis
  •  Run ensemble forecasts
  •  Book accommodation
  •  Install SCM on OpenIFS VM
  •  Get PCA code from Linus & try it
  •  Get USB sticks from comms
  •  Frédéric to check last year's VM will run on classroom PCs and ensure VirtualBox (or VMware) is installed.
  •  Check for observations we might have in the archive for HYMEX that could be used

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?
