20th ALADIN General Assembly : 9-10 February 2016, Budapest

Due to the insecure situation in Europe after the 13 November 2015 events in Paris and the raised terror alert level in Brussels (21-22/11/2015) there was not enough guarantee for a safe travel for the participants and the meetings in Algiers were cancelled.

The LACE Council and the 20th ALADIN GA are rescheduled on 9-10 February 2016, in Budapest.

ALADIN-HIRLAM Newsletter : number 5

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 is mostly dedicated to this 25th meeting.

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.
