Model Dev., 11, 257-281,, 2018.

The purpose of this paper is (i) to define the ALADIN System in relation to the global counterparts IFS and ARPEGE, (ii) to explain the notion of the CMCs, (iii) to document their most recent versions, and (iv) to illustrate the process of the validation and the porting of these configurations to the operational forecast suites of the partner institutes of the ALADIN consortium.

Regular 22nd General Assembly and 3rd joint ALADIN GA and HIRLAM Council

The ALADIN GA and the HIRLAM Council met in the Polish NMS premises in Krakow (Poland) on November 21-22, 2017 : the 22nd ALADIN GA, then the LACE Council and the HIRLAM Council in parallel, then the 3rd joint ALADIN GA - HIRLAM C meeting.

  • Besides the usual items on their agendas, the assemblies approved the Rolling Work Plan 2018 (and its completely renewed format), and committed the resources of their NMS to realised it : the HAC/PAC was asked to further discuss its scope and to follow its realisation.
  • The convergence roadmap (towards a single ALADIN/HIRLAM consortium after 2020) was debated and guidelines for the next steps were given to the PMs and the HAC/PAC.
  • Due to lack of time, the "Tour d’ALADIN" could not be presented : the slides are on-line : these 2017 highlights sent by the LTMs will be detailed in the ALADIN-HIRLAM Newsletter n°10, to be published end of January 2018.
  • The ALADIN budget for 2018 was approved, with a new position (20%F.T.E for a DA coordinator) : the position is opened.
  • A new matrix of the ALADIN consortium was approved after changes in some positions.

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.

25 years later, as defined in the 5th 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 plugging 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.

n.b. 1 : The partition between CSSI (with the extra coordination of a Chairperson) and Support Team is sometimes rather arbitrary. The idea used below for "border cases" is that the chain of responsibility cannot loop twice and that hence structural (already existing for most of them) coordination responsibilities should not be formally subject to one more level of coordination.
Concerning its further evolution, the CSSI+ST composition is meant to be discussed at each ALADIN Workshop.

n.b. 2 : The role of the CSSI Chairperson is not hierarchical but of coordination, information exchange and representation, in agreement with the PM.

n.b. 3 : One untold rule in filling the full CSSI Members and Support Team position was to avoid potential ambiguities or conflicting responsibilities. Hence no PAC Members nor LACE Working Group Leaders (or equivalent) came in line for the above positions.
