Report of the Sixth Session of the JSC/CLIVAR Working Group on Coupled Modelling, Victoria, Canada, 7-10 October 2002
Notice bibliographique
Résumé
CLIVAR is a component of the World Climate Research Programme (WCRP), which was established by WMO and ICSU, and is carried out in association with IOC and SCOR.The scientific planning and development of CLIVAR is under the guidance of the JSC Scientific Steering Group for CLIVAR assisted by the CLIVAR International Project Office.The Joint Scientific Committee (JSC) is the main body of WMO-ICSU-IOC formulating overall WCRP scientific concepts.WGCM endorsed the present membership but recommended that future changes should reflect a better representation of the variety of ocean models used and developed at present within the community.(C.Boening to WGOMD) AR4 (4 th IPCC Assessment Report)In order to meet the timeline for the next IPCC report, WGCM pointed out that the forcing scenarios have to be finalized in early summer 2003.The group recommended to use the original preliminary scenarios used in for the TAR instead of taking new ones, unless the differences are large, to enable intercomparisons with previous calculations.Furthermore, this would provide a larger sample size for intercomparisons and for impact studies.In addition, it was requested that a simple concentration time series for each atmospheric parameter should be provided for each emission scenario and made available on the IPCC and the TGCIA website.If the scenarios are changed, then it is very unlikely that WGII will have time to include work from the new scenarios in the AR4 report.This was also the case for the TAR.(J.Mitchell to draft a letter to the IPCC bureau the above mentioned recommendations.)It should also make clear that IPCC should assess and not direct climate research.WGCM notes that it would be very useful if a set of indices were developed to document important modes of variability in the coupled system.Model results could then be compared using these indices.This would provide a simple, clean way of evaluating model performance.(A.Villwock to JSC, CLIVAR SSG for approval) WGCM felt that the Modelling Intercomparison Projects (MIPS) should in time be more integrated towards an Earth System Modelling umbrella.The Coupled Model Intercomparison Project (CMIP) could serve as the overarching MIP.The group encourages the display of the accomplishments of the MIP's in the newsletters of the various programmes.(A.Villwock to JSC) Idealized Model ExperimentsA letter of invitation for participation will be send out soon.(B.McAvaney). Data ManagementWGCM to ask the JSC to set up and ad-hoc task team on data management with representatives of all WCRP projects to develop a comprehensive data management strategy for WCRP (B.McAvaney and PCMDI to develop 'white paper' for JSC). C20C ProjectSince this activity is performed with atmosphere-only AMIP type runs, WGCM felt that this activity would be better placed under the scope of AMIP.Nevertheless, a coordination of the forcing with the ongoing CMIP activity on (coupled) C20C runs would be useful.(J.Mitchell to report to H. Cattle). Relationship to C4MIPWGCM regards the C4MIP as an activity that could be well placed under the expanded scope of CMIP.This issue should be discussed with GAIM, then be brought to the JSC for endorsement.(WGCM to discuss with GAIM) 13.Website for WGCM WGCM asks to pursue the idea for a Website for the panel to be set up under WCRP.(A. Villwock to contact JPS)

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.

Scores machine (provisoires)
Les deux têtes enseignantes du modèle étudiant, lues sur ce travail. Un score ordonne la base pour la relecture; il n'affirme jamais une catégorie, et le statut de validation accompagne chaque rangée tel quel.
Scores de référence d'un modèle non mature (critères de maturité non atteints, 7 itérations). Un score ordonne; il n'affirme jamais une catégorie.
score_only:v0-immature-baseline · tel quel depuis la passe de notation : score_only signifie que le nombre peut ordonner les travaux, et qu'aucune étiquette de catégorie n'en découleClassification
machine, non validéePrédiction automatique; un appel candidat d’une seule source (Gemma direct ou Codex distillé), pas un consensus.
