The "waves school" will start on November 4 . It is intended for graduate students, post-docs, researchers, engineers or consultant that are dealing with ocean wave data of one form or another. The school will draw from the latest developments made possible by the IOWAGA, NOPP-waves, & Previmer, projects, and will benefit from the new (beta) release of the WAVEWATCH III (R) version 4 from NOAA/NCEP.
The WW3 code version to be used is 4.12 . our to-do list
The program is designed in such a way that people that only use wave data and do not want to run a model can attend day 1 & 2 while the real brave geeks that actually want to install WAVEWATCH III and run the thing will be welcome to stay until late Friday.
- Monday 4, 9-10 AM, Ifremer, Salon de l'ocean: Welcome, coffee, logistics, discussion of participants objectives (e-mail discussions before Monday 4 are welcome): what do you want to acheive / understand with wave data and models.
- Monday 4, morning, starting at 10 AM, Salon de l'Océan (lectures)
- basic principles of ocean waves: elevations, velocities pressure.... and spectra ( 1 hour: Fabrice Ardhuin)
- different spectral wave parameters: what can be measured and what is usually measured ( 20': Fabrice Ardhuin)
- short break (lunch ticket sales)
- wave measurement databases: altimeter and SAR data, buoy data, seismic noise, IOWAGA & Previmer model databases ( 30': Fabrice Ardhuin)
- the NCEP hindcast and forecast database ( 30': Henrique Alves)
- examples of ocean engineering applications: long term statistics ... ( 30': Michel Olagnon)
- Lunch break 1 PM - 2 PM - Tickets for lunch at the Ifremer restaurat will be available for sale (~ 8 € / day).
- Monday 4, afternon, starting at 2 PM (hands-on practical training: computer rooms at IUEM)
- Model and data file formats: ASCII & NetCDF, reading tools. (M. Accensi)
- Exercise starting from spectra, visualizing and recomputing integrated parameters
- using long wave data time series (??)
- reading wave model output and altimeter data, performing simple error analysis on wave models
- coffee break from 4 PM to 4:30 PM & Posters
- comparing ocean wave model or buoy data and seismic noise records
- closing at 6 PM.
- Dinner somewhere ( downtown Brest, around 8 PM).
- Tuesday 5: Physical parameterizations and numerics, 9 AM (lectures, Ifremer, Salon de l'Ocean)
- the wave action equation and source terms, basic principles (F. Ardhuin or H. Alves or A. Roland 30').
- parameterizations in wave models and impacts on various quantities: from Hs to air-sea fluxes. Why results from
this WW3 different can be different from that or that version of WAM or SWAN. So why do we have different wave models? (F. Ardhuin and/or H. ALves 1h50 hours).
- forcing fields: quality of wind fields, validation datasets
- coffee break
- wave model numerics: principles (A. Roland. 1 hour)
- wave model numerics: the dark side of limiters, SWAN's "renormalization" .... (A. Roland, 50 minutes)
- Tuesday 5: Physical parameterizations and numerics. afternoon (hands-on practical training)
- analysis of different model hindcasts and different model resolutions. (spatial, possibly spectral too).
- coffee break and posters from 4 PM to 4:30 PM.
- evidence of discretization and numerical scheme effects on coastal wave model results
- looking at directional spread
- closing .. around 6 PM
- Wednesday 6, morning (9 AM):
- Installing and running WAVEWATCH III: code structure, pre-compilation, running the model: the basic steps, from ww3_grid to ww3_out* (H. Alves. 2 hours ... more?)
- coffee break
- introduction to grid types and multi-grid (F. Ardhuin 30 h).
- specific aspects of unstructured grids (A. Roland 1h)
- lunch break (12:30 to 1:30 PM)
- Wednesday 6, afternon (hands-on practical training)

- running a triangular mesh grid and using the results. From preprocessing to post-processing.
- closing at 6 PM or before
- Thursday 7, morning (9 AM, salon de l'océan)
- grid generation for regular grids (H. Alves. 1 hours)
- Running WW3 as a multi-grid system (M. Accensi. 1 hours)
- Mesh generation with polymesh (A. Roland. 1 hours)
- Thursday 7, afternoon: (hands-on practical training, computer rooms at IUEM )
