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 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: 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 (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 ( 30': Fabrice Ardhuin)
examples of ocean engineering applications: long term statistics ... (30': Michel Olagnon)
Lunch break 1 PM - 2 PM
  • Monday 4, afternon, starting at 2 PM (hands-on practical training)
Model and data file formats: ASCII & NetCDF, reading tools (M. Accensi)
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. Morning:
parameterizations in wave models and impacts on various quantities: from Hs to air-sea fluxes
forcing fields: quality of wind fields, validation datasets
wave model numerics: principles
wave model numerics: the dark side of limiters, SWAN's "renormalization" ....
  • Tuesday 5: Physical parameterizations and numerics. afternoon (hands-on practical training)
evidence of discretization and numerical scheme effects on coastal wave model results
  • Wednesday 6, morning:
Basic information on installing and running WAVEWATCH III
desingning and optimizing unstructured grids
  • Wednesday 6, afternon (hands-on practical training)
the polymesh fun fair: grid generation for unstructured grids
  • Thursday 7, morning:
Running WW3 as a multi-grid system
grid generation for regular grids
  • Thursday 7, afternoon: (hands-on practical training)
more fun stuff (gridgen, polymesh ...)
  • Friday 8, morning: to be defined (possibly something more interactive on the different projects of the participants)
