The 10th ALADIN workshop, dedicated to scientific progress and the evaluation of the second medium-term research plan , was organized in Toulouse on June 7-8. It was a real success, with 44 participants from 15 countries. Let us just quote the chairman of the last session, Andras Horanyi, : " Congratulations to Météo France for organizing the workshop: especially for the world record in the number of presentations per day (22, yesterday) " and mention the friendly informal celebration of the 10th ALADIN anniversary, prepared by visitors on the Thursday evening.
