namelistfc

The 'ecmwf' directory contains the files as used at ECMWF to run this experiment:

• namelistfc : copy this file to 'fort.4' to run the experiment (modify as required)
• NODE.001_01 : this is the model output file as run at ECMWF. If your run fails, it may be useful to compare with this file.

Suggested experiments

As ERA-Interim is an improved analysis, forecasts from these starting initial conditions will not reproduce the actual forecast of the storm. For that, the model should be run with operational data.

• What's the impact of the different 'lead times' on the forecast of the storm (i.e. starting from different dates)?
• What's the difference and why between forecasts started with the operational analysis of the time and the ERA-Interim analysis?
• What's the impact of resolution on the forecast of the storm?
