1. 7th ALADIN Workshop : Recent and planned operational exploitation of ALADIN model, hold in Ljubljana on November 17-19, 1999
During this workshop, it was generally recognized that the use of ALADIN NWP products has increased very much since more and more users have access to the enhanced data (special parameters & products, colorful visualization, etc.) and find better ways to use it in their decision-making process.
Therefore the efforts started to shift from the conventional use of standard forecast charts also towards the final part in the forecast production chain.
With the present and foreseen quality of ALADIN we can expect that it will be so even more in the future. An exchange of information and maybe even common undertaking also in these fields within ALADIN community was recognized to be very valuable since it reduces the duplication of efforts (and avoids the employment of NWP human resources in the development of more technical applications).
Many topics were discussed (Visualization, Nowcasting, Verification, Applications, Automatic forecast generation) and concrete actions were decided :
It was also proposed that besides the usual forecasting themes the above listed topics of discussion should be announced for the next "users'" workshop in order to increase the interest towards the end-users of ALADIN products.
The complete Minutes of the discussions have been sent to each participants and are available on ALADIN Web : http://www.cnrm.meteo.fr/aladin/meetings/meetings.html .
2. Assembly of ALADIN Partners hold in Lisbonn on December 6th, 1999
The Agenda was presented in the Newsletter 16. Some points have already been completed such as :
* Three main topics were focussed: maintenance and improvement of the operational versions, high resolution modelling and data assimilation. For each of these 3 generic targets, the relative importance of themes was established and these were distributed, by priorities, in very/high, medium and long term.
* At the same time, it was stressed what work was completed on those themes during 1999 and the expected work to be done during the year 2000 on: Physics, Dynamics (including coupling) and Data Assimilation.
* The approved medium-term reasearch plan is available on our public ftp.
Stricter rules for participation to the maintenance effort inside the ALADIN partnership were accepted :
* The participation of each ALADIN team to phasing must be at least 1 person once a year. It can be more for the largest teams (more than 4 full-time equivalent persons for instance). The minimum size of a phasing team is 8 persons for a full cycle, less for intermediate cycles if any.
* Only one unexperienced person per phasing team is accepted. This newcomer must of course have some basic knowledge of ALADIN.
* An ordered list of all ALADIN scientists will be elaborated. Persons will be invited following this list in "rotation mode", so that everyone will contribute but not very often.
* Each team will send its own part of the list, mentioning constraints if any, to the Toulouse support team. Otherwise the list of quarterly contributions will be used.
* Phasing is centralized in Toulouse since a very close cooperation between ALADIN and ARPEGE scientists is required for this crucial exercise. The stays are usually 6 weeks long, costs may be supported by Météo-France. Deported validation of cycles are accepted as contributions to phasing exercises exceptionally, for technical options that cannot be validated in Toulouse.
It was also admitted to dedicate 10% of the ALADIN effort on the maintenance. Maintenance includes not only phasing, but also code optimization and cleaning, code documentation and the preparation of databases for the use of all partners.
In accordance with the decision taken during the Assembly, the Directors of ALADIN NMS were asked to commit on the participation of members of their National Meteorological Service to the ALATNET Seminar on "High Resolution" Modelling : full commitments on the number of students, on the previous knowledge of NWP and ALADIN these will have previously acquired and on their future involvement in the project have been received and the decision to organize the Seminar was taken;
* EWGLAM (with co-ordination of Germany);
* SRNWP (with a focal point by the Netherlands);
* ALADIN,
with no real effect yet. A well running example is the one by WMO on the scores for global modelling, with a decentralized way of functioning. The Assembly decided to endorse the following actions:
(1) the need for each NMS to nominate a contact point dedicated to verification : the e-mail list (verifala @meteo.fr) contains the addresses of the nominated contact points;
(2) start a WMO like, i.e. decentralized, exchange of scores (but using the same definitions and same parameters as in the EWGLAM project);
(3) computation by everyone of scores for its geographical domain using the stations recommended by EWGLAM (with special attention of Morocco, not included in EWGLAM);
(4) scores sent back to all other contact points.
If this first attempt is successful, it will open the way to a broader cooperation, at the European level for the exchange of scores, and towards a better coordination of subjective verification and the collection of typical situations inside the ALADIN partnership.
The Minutes of the Assembly have been sent to all ALADIN Partners by Mario Almeida and are available on the ALADIN Web : http://www.cnrm.meteo.fr/aladin/meetings/minutesass4.html .
