Regular 23rd General Assembly and 4th joint ALADIN GA and HIRLAM Council, Zagreb, November 19-20, 2018

The ALADIN GA and the HIRLAM Council met in Zagreb (Croatia) on November 19-20, 2018 : the 23rd ALADIN GA, then the LACE Council and the HIRLAM Council in parallel, then the 4th joint ALADIN GA - HIRLAM C meeting.
The minutes have been approved by the participants and are on-line :

  • The 3 PMs (ALADIN, HIRLAM, LACE) reported on the realisation of the Rolling Work Plan 2018 and presented some highlights on the common and R&D activities. The assemblies congratulated the Members for the good realisation of the Rolling Work Plan 2018 and approved the Rolling Work Plan 2019 and the committed manpower.
  • The assemblies approved the "scope document" they had tasked the WG (PMs, HAC/PAC chairs, MF PAC rep., CSSI chair) with: this document proposes a scope for the future single consortium. The assemblies gave the same WG guidelines to go further toward the single convergence and prepare a draft MoU, to be discussed at the next joint meeting of the ALADIN GA and HIRLAM C.
  • The "Tour d’ALADIN" was given by Piet : the slides are on-line : these 2018 highlights sent by the LTMs will be detailed in the ALADIN-HIRLAM Newsletter n°12, to be published end of January 2019.
  • Piet reported on the 2018 common activities, DA coordinator, Code Architect and ACNA activities (a document has also been published), DA coordinator, Code Architect, ACNA, ..
  • The ALADIN budget for 2019 was approved.
  • A new matrix of the ALADIN consortium was approved after changes in some positions (the GA chairs and vice-chairs were re-elected for a two-year period).

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.

2nd Meeting of the Expert Team on Surface Processes, Zürich, 15 September 2010
Article published on 29 September 2010
by JFM by

A second meeting of the Expert Team on surface processes took place during the last EMS conference in Zürich and was kindly hosted by Meteo Swiss, thanks to Jean-Marie Bettems. The first part was devoted to the description on the database of in-situ measurements for local validation of NWP land surface schemes. This activity which is part of the COLOBOC project of the COSMO consortium has been endorsed by SRNWP in order to make the data available to our community. The second part was devoted to presentations on the current activities of each consortium on surface processes.

Minutes of the meeting devoted to the discussion about the SRNWP Data Pool (written by J.-M. Bettems)

An important conclusion of the meeting was to encourage SRNWP consortia to make use of the dataset for validation studies. This action is important if we want this database to be maintained and enriched with more recent data. All members of SRNWP can register on the following web site and then download the available data :
