The 1^st AROME training course took place in Poiana Brasov (Romania), on November 21-25, 2005. 53 people from 23 countries attended the one week Seminar. 10 teachers gave 22 hours main lectures on the most important points for running AROME in the forecast mode, considering both the theoretical and the practical aspects of:

• Méso-NH physics
• ALADIN-NH dynamics
• AROME prototype, including the externalized surface module.
