The main purpose of this conference was to review the results of the numerical experiments carried out so far on WIND data at the UK Meteorological Office (MO) and Los Alamos and examine their implications for future development of the mesoscale model heirachy at ASL. The opportunity was also used to brief the participants on the present status of validation and archiving of the field data from the four phases of the project; this was done on the first day by Dr Cionco and his ASL colleagues. The draft final report of the MO experiments and the conclusions drawn from these was presented by Professor Pearce and Dr Alpert on the second day, followed by a presentation by Dr M Williams of his recent results from SIGMET. Considerable discussion ensued following which a specific programme of modeling activities using SIGMET was agreed for Dr Williams and the ASL group to carry out over the next six months. It was agreed that these tasks should be completed before the model is used in an extensive series of integrations using WIND data for validation purposes.
