    Report on Training Workshop on Use of GDPFS products

    (Dakar, 21-25 November 2005) by Joël Martellet

INTRODUCTION

    The workshop was opened at 9.30 a.m. on Monday 21 December 2005 in the Hotel NGor à Dakar, by the Chief of Cabinet, representing the Minister of Tourism and Aviation Transports, Mr Ousmans Masseck-Ndiaye. He welcomed the participants (45 including 24 Senegalese - from 20 countries plus ACMAD see Annex I). He

    recalled that the Meteorology was playing a fundamental role for sustainable development. He appreciated very much the cooperation with WMO, in particular for the effort done with a view to diminish the technical and information gap between the South and the North. He wished that the workshop would help the forecasters to understand fully the new techniques in constant development and evolution. As representative of the WMO Secretariat, I thank the republic of Senegal for hosting the workshop and all the staff of Météorologie Nationale who worked hard to organize the workshop. The different subjects of the workshop were introduced. I recalled the importance of ensemble forecasting as stressed by WMO Congress and by RA I in their last sessions and the need for training in that domain. Forecasters should make a cultural revolution to adapt to probabilistic forecasting and multi-forecasts products, outcome of the ensembles. Operational NWP on limited area was more and more implemented in Africa. One would have to make use of these new products. The indispensable verification techniques will be explained. Cooperation for data exchange will be discussed. And I urged participants to take advantage of the CD-ROM given to them at the end of the workshop, to use that information to train their own colleagues in their meteorological services. The programme of the workshop given in French language is given in Annex II.

LECTURES

GDPFS system-verification

    The lectures started by a presentation given by myself on the GDPFS system and the products available, then Mr Lalamine Sonko, chief of RTH Dakar presented the status of reception system for GDPFS products in RA I (RETIM, PUMA, Internet) and also the status of GTS in RA I. He stressed that only 50 % of generated data are properly exchanged within RA I. He also stated that Internet could help, even at the national level and between one NMC and an RTH.

    Ms Rachida El Ouaraini presented the use of GDPFS products in Casablanca, and the production of the ALADIN models in Casablanca. There was a will to make available ALADIN NORAF products (which extends beyond the Equator) on RETIM 2000. Mr Madiagne Thiaw chief of the forecasting centre in Dakar, presented the activities of the centre related to the use of GDPFS products. The necessity and techniques of verification of products were explained by Mrs Siham Sbii from DMN, Morocco.

NWP perspectives

    The scientists from DMN Senegal, Dr Aïda Diongue-Niang, Dr Marianne Diop-Kane presented various case studies, especially on squall lines. Two cases of squall line simulation were presented and showed the feasibility and potential useful products expected from the NWP over West Africa.

    Dr Aïda Diongue presented the perspective for running an operational LAM in RSMC Dakar. It would improve the local forecast. She presented all the advantages of running a limited area model and all the difficulties. At least a 2 gigabits ADSL connection was required to obtain efficiently boundary conditions on Internet. Running a regional model would provide new products that were not always available

    from the advanced centres. It would permit an improvement of local forecasting. Mr Aboulaye Sarr reported on the running of MM5 model over Senegal for the purpose of rain enhancement project (Baawan: rain improvement (provoked) project). It was stressed that 90 % of precipitation in Sahelian Africa were associated with squall-lines. Case studies have shown that modeling of squall-line was quite feasible, especially those associated with orographic revival linked to the Fouta-Djalon mountains. The AMMA experiment will include this aspect in their activities. In 2006 a LAM will be operationally run in Dakar RSMC. A good operational team can be constituted in RSMC Dakar for operational NWP and achievements should be seen in this field during 2006.

EPS products

    A whole day was devoted to ensemble prediction systems, which were presented by Ms El Ouaraini and mostly by François Lalaurette, Director of the Meteorological College at Météo-France and previously chief of Meteorological Operations at ECMWF. Many participants discovered that subject, and would like more studies and methodologies to see the evaluation of the EPS products over African sub-Saharan and equatorial areas. The results of the verification of EPS products should be made available.

Perspectives for ACMAD, TDCF, ALADIN NORAF

    Perspectives for ACMAD in NWP were explained by Zilore Mumba. The future for products of the ALADIN NORAF model for West RA I was described by Mme Siham Sbii. On Thursday, I informed the participants on the Table Driven Code Forms (TDCF) and explained the main aspects of the WMO migration plan to TDCF. Within that context a new code for describing squall-line in CREX was defined (see Annex III)

CONCLUSION-RECOMMENDATIONS

    Although there were not many lecturers from outside RA I the quality of the presentations was highly appreciated, and it shows that in Africa there is qualification and competence. Sometimes, it is just the organization and the means, which lack for an efficient implementation in RA I of modern meteorological techniques. A questionnaire passed to the participants at the end indicated the overall satisfaction of the participants.

    The last day, some time was dedicated to the production of a set of recommendations approved by all the participants which will or could be used for consideration by the Planning and implementation of the WWW Working Group for RA I or by other groups related to RA I or CBS (see Annex IV).
