Jean-François Geleyn passed away on 8 January 2015. Jean-François was suffering with his health recently, but the brutal course of events leaves the ALADIN community suddenly orphaned.

Jean-François’s impact on the current generation of NWP specialists is unparalleled, both scientifically and on a human level.

Jean-François first developed the physics of the ECMWF model in the 1970s. Back in Météo-France Paris, he became head of the NWP team. He proposed the concept of variable mesh in ARPEGE and developed the cooperation with ECMWF around ARPEGE/IFS. He built a new NWP team in Toulouse in 1991 (GMAP team) and run it until 2003.

Jean-François created ALADIN in 1991. He acted as ALADIN Program Manager, the main executive officer of the ALADIN Consortium, years before this position was officially defined in the ALADIN Memorandum of Understanding. Until 2010 (a tribute was payed to his 20 years in ALADIN during his last General Assembly as ALADIN PM in Prague), he led the life of the ALADIN consortium and started the merge between the ALADIN and the HIRLAM consortia and a productive scientific interaction within the SRNWP program with the other European consortia. For this outstanding contributions to the fostering of cooperation among scientists in European countries, he received the European Meteorological Society Silver Medal in 2011. As a token of recognition, in March 2011, Jean-François became visiting Professor at the department of Physics and Astronomy of Ghent university, Belgium, passing his longstanding expertise on NWP to students.

The ALADIN community loses its icon and beacon.

A ceremony was organized at the crematorium of Cornebarieu, near Toulouse on Saturday 17 of January at 10:00. Many tributes were payed to Jean-François (see Piet’s tribute on ALADIN behalf). A condolence book was prepared and the numerous messages received at Météo-France or in ALADIN were joint to it. The collection organized by Patricia was used for ornamental funerary articles on behalf of Météo-France and ALADIN and the remaining money will be donated to some foundations for medical research, according to the family choice.

On January, Monday 19th, the opening session of the A.M.A. was replaced by speeches paying homage to Jean-François and the Le Verrier medal Jean-François should have get at his retirement on January 22nd was given to his wife Radmila.

The concept of the ALADIN project was proposed by Météo-France in 1990, with the aim of building a mutually beneficial collaboration with the National Meteorological Services of Central and Eastern Europe. This collaboration was to be in the field of Numerical Weather Prediction (NWP), which provides the basis for the forecasting tools of modern meteorology. The easy to translate acronym (Aire Limitée Adaptation dynamique Développement InterNational) clearly indicates the major axes of this project at its beginnings.

20 years later, as defined in the 4th Memorandum of Understanding,

The goal of the ALADIN Collaboration is to improve the value of the meteorological, hydrological and environmental warning and forecast services delivered by all Members to their users, through the operational implementation of a NWP system capable of resolving horizontal scales from the meso-beta to the meso-gamma scale and improving the prediction of severe weather phenomena such as heavy precipitation, intensive convection and strong winds.

This objective will be fulfilled through continuation and expansion of the activities of the ALADIN Consortium in the field of High Resolution Short Range Weather Forecast, including:

  • Maintenance of an ALADIN System (...);
  • Joint research and development activities, on the basis of the common Strategic Plan and related Work Plans, with the aim of maintaining the ALADIN System at scientific and technical state of the art level within the NWP community;
  • Sharing scientific results, numerical codes, operational environments, related expertise and know-how, as necessary for all ALADIN Consortium members to conduct operational and research activities with the same tools.

About one hundred scientists, from sixteen countries, each with its own specificity in resources and knowledge base, are permanently contributing to the progress of ALADIN NWP system. They are working together on a modern code of the atmosphere that definitely deserves its proper place between the European state-of-the-art NWP models: 80 Full-Time Equivalent persons in the last years of the project’s life. This code is now operated every day in fifteen Euro-Mediterranean countries, on a huge variety of computing platforms ranging from a PC Cluster under Linux to Vector Computers.

ALADIN consortium had a number of unique successes in the past : for instance, the pluging of an existing physics parameterization in the existing code, leading to the AROME model; ALADIN is at the forefront of the gray-zone problematics with the ALARO physics; ALADIN dynamical core is remarkably stable; ...

ALADIN also allowed to build a high-level scientific team, distributed in sixteen countries that managed to reach the level of the best research centres, as witnessed by the PhD theses and publications in international journals. The General Assembly of Partners, the workshops, the meetings, the newsletters regularly offer opportunity of various exchanges within the ALADIN community.

ALADIN is preparing for the serious evolutions expected within the NWP landscape in the coming five to ten years. There is the ever-lasting question where to draw the line between resolved vs. parameterized processes. There is the question of the efficiency and the scalability of ALADIN dynamical core. There are the external drivers, such as the demands of the end users, and the evolution of the high-performance computing machines. Additionally a serious reorganization of the code is now at hand, in particular within the OOPS project. Besides that, the international meteorological context is steadily changing, specifically with the merger of the ALADIN and the HIRLAM consortia.

The ALADIN Project within the European collaborations in Numerical Forecast
Article published on 12 January 2011
by Patricia

  • ALADIN is a consortium of the European SRNWP Network
    JPEG - 326.7 kb
    SRNWP Consortia in Europe
  • Informations about the other consortia could be found on SRNWP webpages or on the websites of each consortium :
    • COSMO,
    • UKMO,
    • HIRLAM : ALADIN had a research cooperation with HIRLAM for years; an enhanced cooperation started in 2004 and a Cooperation Agreement between the ALADIN consortium and the HIRLAM consortium was first signed on December 6, 2005 and renewed on December 1st, 2010: the respective strengths and weaknesses of both consortia complement each other well and, in the recent years, in the so-called "HARMONIE" ( Hirlam Aladin Research on Meso-scale Operational NWP in Euromed) dynamics, ALADIN and HIRLAM have collaborated more and more closely, giving a new impulse to the European structuring of NWP activities.
    • LACE : ALADIN has strong links with LACE, LACE being a grouping of ALADIN members, using aladin software : first operational ALADIN-LACE model was run in Toulouse where the LACE management group was hosted (1994); in 1998, the LACE operations were transfered to Prague Regional Center; from 2003, each RC LACE Member is responsible for its own operational NWP system, but scientific research and development is co-ordinated within the LACE project.
  • ALADIN is linked to ECMWF through the software protection agreement between ECMWF and Meteo-France signed on 19/02/1999.
