After the Joint 25th ALADIN Workshop & HIRLAM All Staff Meeting 2015 (13-16/04/2015, Elsinore, Denmark), please consult the dedicated webpage : agenda, list of participants, pdf files of the presentations and posters, minutes of the discussions and working groups, some photos.

90 people from 23 countries (all the 16 ALADIN countries were represented in Elsinore) gave more than 50 presentations and presented about 35 posters. Some working groups and many side meetings also took place during the week.

The ALADIN Local Team Managers held their 18th meeting (the first one ever where all partners were represented).

The ALADIN CSSI and the HIRLAM Management Group had their annual coordination meeting on Friday, at the Danish Met Institute premises in Copenhagen.

The 5th edition of the combined Newsletter of the HIRLAM and ALADIN consortium will be dedicated to this 25th meeting. People who gave a presentation or presented a poster in Elsinore are kindly asked to write down an article and send it to Patricia before the end of July (please do use the proposed templates).

The 12th HAC meeting and the 3rd joint HAC/PAC meetings took place in Helsinki in May 21st, 2015. The major topic was the ALADIN-HIRLAM convergence : the outcomes of the common declaration adopted by the 1st joint ALADIN General Assembly & HIRLAM Council, the outcomes of the data policy task force guidance about the ALADIN/HIRLAM common agreement for the next MoUs and the organization of the 2nd joint ALADIN General Assembly & HIRLAM Council and the MoUs signatures in Alger.

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 cooperation with African countries
Article published on 2003
by Patricia by

Following the conclusions of the working group’s meeting in Ston-Dubrovnik (Croatia - 19.04.2002) and of the WMO meeting in Pretoria (RSA - 10.2002), and within the cooperation between ACMAD and Météo-France on one hand and between ACMAD and DMN Morocco on the second hand, to develop NWP in Africa, a new configuration of ALADIN, called ALADIN-NORAF, is running operationally in Casablanca since the 24th of February. The NWP products issued from this new model should be sent to the covered NMSs via RETIM 2000 or Internet. The final agreement is for the following list of African countries : Algeria, Benin, Burkina-Faso, Chad, Egypt, Eritrea, Gambia, Ghana, Guinea, Guinea-Bissau, Ivory Coast, Liberia, Libya, Mali, Mauritania, Niger, Nigeria, Senegal, Sierra-Leone, Sudan, Togo (Morocco and Tunisia being full ALADIN members).

The ALADIN-NORAF domain covers nearly all the African countries to the north of the equator (from 43.86°N to 0.70°S and from 36.20°W to 56.48°E). This model is run twice a day, at 00 and 12 h UTC, with respectively 72h and 60h forecasts. Data assimilation is realized every 6 hours, using optimal interpolation in a first step. By the end of this year Morocco plans to use raw radiances from TOVS AMSU-A with a 3d-var implementation. The coupling files are provided by Météo-France from the ARPEGE stretched global model. In parallel a local model ALADIN-ALBACHIR, covering Morocco, is run without data assimilation and coupled with the regional model ALADIN-NORAF.

A new users’ group, the Committee of Users of the Model ALADIN-NORAF (CUMAN), has been created by ACMAD to define the best products which should be produced and distributed to the NMSs, and to discuss on the different topics linked to the exploitation of this new model. The first meeting of the CUMAN was hold in Casablanca in 2003.
