Priority is the analyses, oper ens & expt gioi

Analyses:

T1279L137 20120915 00Z (single start date), 10 days (to 20120925 00Z), 3hrly? (if not 6hrly)  6hrly  (note start date for AN is different to forecasts - if starting from 15th Sept is too much, start from 18th)

If data size is an issue only use MSLP & T2m for 00Z 15th - 18Z 19th, with all fields from 20th to 25th.

HRES:

20120920 00Z, 5 days (to 20120925 00Z), 6hrly, native grid

Same fields as analysis (see below)

Operational ensemble as used in 2012:

TL639L91. 20120920 00Z (single start date), 5 days (to 20120925 00Z), 3/ 6hrly ? (all members)

Same fields as analysis

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

TCo639L91. 20120920 00Z (single start date), 5 days (to 20120925 00Z), 3/ 6hrly (all members)

Same fields as analysis

Uncertainty runs:

TL319L91. No NEMO coupling, wave model off (OpenIFS config)

May not get time in workshop to look at these but Frédéric would like to have the data available.

...

(c) SPPT/SKEB only - exptid 'gin7'

Dates/steps/fields as above.

Grid resolution (post-processed)

Needs to be good enough to resolve Hurricane Nadine in the plotting. What did we use last year?Use native grid of analysis/forecasts if at all possible. Revise if total data is going to be more than 10Gb.

Fields : 

MSLP, T2m, 10m winds, 6hrly accum. total precipitation,

SST : from analysis, HRES, oper. ensemble and gioi (to compare)

Geopotential, temperature,  potential temperature & equivalent potential temperature, winds (U/V), relative humidity (rather than sp. hum.),  @ 200, 500, 700, 850 hPa,

also 925hPa for winds & humidity only (not sure if this is archived?)

PV + wind (U/V) @ 330 K isentrope (see Fig.10 in paper)

...

If too much data, make the full level data only available at specific times (e.g. daily). Failing that pre-plot images.

...

Useful for the students to compare with Emagrams.

Which location(s)?

Model or obs?

We could pre-plot these as this is not particularly interactive.

Observational data

• possibly synop data to add to plot similar to fig2?

...

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

Other data- poss. satellite imagery

Satellite images to be provided by ENM & included on VM. Due to licensing restrictions we can't provide the GRIB data on the VM.

Perhaps we can overlay geotagged TIFs?

Plots

To be completed (but very similar to 2015 workshop)

Usual plots

...

Icons

• 1x1, 2x2

...

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

...

• stamp maps

...

• RMSE curves geopotential (500hPa), RMSE plumes

...

• spaghetti plots
• nadine track icon
• PCA (new)
  

Horizontal / isobaric maps

Students should do at least:

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

...

• + temperature at 500hPa -->

...

• mid-trop localization of the cold cutoff and warm Nadine. On the deterministic forecast we should not see Nadine and the cutoff 'meeting' with Nadine moving eastward.
• Geopotential + 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.

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. 

• HRES & analysis only. Perhaps ECMWF ensemble? (modified 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.

From Frédéric: (15/Mar)

5. SCM:

I have the radiation exercices and convection exercices from previous workshops. It could be nice to look at the convective tendencies in Nadine's deep convection to illustrate of the convection scheme works. I am sure Peter Bechtold has great ideas about that !

...

•  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 licensingimagery  (ENM to provide images to avoid licensing issues)
  
•  Extract HRES & analysisdata from the archive.
•  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
