Plots from the Metview exercisesThe gallery below shows example plots from all the practical exercises the participants were able to do with the Metview macros developed by Sandor Kertesz in ECMWF's forecast department. Most of the plot types can be animated in time with Metview (not shown). For more information, please contact: openifs-support@ecmwf.int. |

ProbabilitiesTwo ensemble forecasts datasets were provided for the workshop. The 2012 operational ensemble and a reforecast using the operational ensemble of 2016.  Image Added | Probabilities of total precipitation greater than 20mm
for both ensembles at 3 different forecast times. |

Concerning the accommodation it depends whether you want to be in Toulouse center or not. Maybe the Ibis and Mercure are cheaper than The Pullman... You'll have to take the metro and the bus to come to Meteo-France (approx 30 minutes) If you want to be 2 minutes walk from Meteo France there is a B&B just next side of the road. But Meteo France neighborhood is not really amazing for a first visit in Toulouse... I live in a small town called Cugnaux, at about 20 minutes from Toulouse. If you are interested I can catch you in the morning. Here is a nice address of a bed and breakfast, maybe a little expensive but with a huge breakfast in the morning : http://www.la-cognee.com/?lang=2 |

Nadine seems to be a nice and recent case to illustrate predictability issues with OpenIFS. It would be great to use the SCM to illustrate the parametrization of convection. Half a day dedicated to Metview would also be useful. A colleague of mine could talk about Hymex field campain and CRM ensemble prediction of Mediterranean events with AROME. Maybe something about the clustering technique used by Pantillon too ? |
