Abstract. Low-flow simulation and forecasting remains a difficult issue for hydrological modellers, intercomparisons can be extremely instructive assessing existing low-flow prediction models developing more efficient operational tools. This research presents the results of collaborative experiment conducted to compare on 21 unregulated catchments in France. Five (four lumped storage-type – Gardenia, GR6J, Mordor Presages one distributed physically oriented model SIM) were applied within...
The international effort toward climate services, epitomised by the development of Global Framework for Climate Services and, more recently launch Copernicus Change Service has renewed interest in users and role they can play shaping services will eventually use. Here we critically analyse results five service prototypes that were developed as part EU funded project EUPORIAS. Starting from experience acquired each projects attempt to distil a few key lessons which, believe, be relevant wider...
Soil moisture is a key parameter in different environmental applications, suchas hydrology and natural risk assessment. In this paper, surface soil mappingwas carried out over basin France using satellite synthetic aperture radar (SAR)images acquired 2006 2007 by C-band (5.3 GHz) sensors. The comparisonbetween estimated from SAR data situ measurements shows goodagreement, with mapping accuracy better than 3%. This result that themonitoring of images possible operational phase....
Abstract. The FP7 project EUPORIAS was a great opportunity for the climate community to co-design with stakeholders some original and innovative services at seasonal time scales. In this framework, Météo-France proposed prototype that aimed provide water resource managers tailored information better anticipate coming season. It is based on forecasting system, built refined hydrological suite, forced by coupled forecast model. particularly delivers probabilistic river flow prediction basins...
This work discusses the ability of a bias-adjustment method using empirical quantile mapping to improve skills seasonal forecasts over Europe for three key climate variables, i.e., temperature, precipitation and wind speed. In particular, suitability approach be integrated in services provide tailored predictions local applications was evaluated. The workflow defined order allow flexible implementation applicability while providing accurate results. scheme adjusted monthly quantities from...
Cette communication a pour objet de présenter l'exploitation qui été réalisée par le Service Central d'Hydrométéorologie et d'Appui à la Prévision des Inondations (SCHAPI) chaîne SAFRAN-ISBA-MODCOU Météo-France. L'humidité couche racinaire d'ISBA, Hu2, s'est révélé être un bon indicateur - notamment en comparaison d'indices pluies antérieures- expliquer variabilité saisonnière réponse plusieurs bassins rapides quelques centaines km2. Ce constat conduit SCHAPI réaliser diffuser, manière...
The Paluclim project managed by the French Centre National d'Etudes Spatiales (CNES) found that total rainfall for a 3-month period is confounding factor density of malaria vectors in region Nouna Sahel administrative territory northern Burkina Faso. Following models introduced 1999 Craig et al. and 2003 Tanser al., climate impact model risk (using different indices) was created. Several predictions this at temporal scales (i.e. seasonal, inter-annual low-frequency) were assessed using...
The Paluclim project applied the tele-epidemiology approach, linking climate, environment and public health (CNES, 2008), to rural malaria in Nouna (Burkina Faso). It was analyze climate impact on vectorial risks, its consequences entomological risks forecast. objectives were to: 1) produce maps region, 2) dynamic larvae sites their productivity, 3) study 4) evaluate feasibility of strategic larviciding approach.
Dédiée aux sciences de l'atmosphère, au climat et à d'autres domaines connexes, tels que l'océanographie ou la glaciologie, La Météorologie, révisée par des pairs publiée en français, s'adresse professionnels météo du climat, enseignants, étudiants, amateurs utilisateurs. Météorologie a succédé 1925 l'Annuaire Société météorologique France (1852-1924) qui avait lui-même (1849-1851).

<p>There has been a growing interest in extending forecast lead times to facilitate water resources planning and management during droughts low-flow events. This can be partly achieved by improving integrated hydrometeorological forecasting systems, which offer forecasts of future meteorological hydrological conditions over continuous space time scales. Several initiatives have recently carried out at continental or global scales, Europe worldwide, set up chains that run with...
<p>In the framework of EU <span>C</span><span>opernicus</span> <span>Climate Change Service </span><span>(</span>C3S) program, a new coupled system has been developed at Météo-France (MF) to carry out seasonal forecasts 7-month range. This (called S7) is in operation real time since October 2019. S7 based upon MF climate model CNRM-CM6 used...
<p>In order to develop seasonal forecast applications, raw data generally need be corrected remove their systematic errors and drifts in time. In the climate community, methods based on quantile mapping techniques are quite common for easy implementation. framework of SECLI-FIRM project, we have tested a refinement by conditioning correction weather regimes, take large-scale circulation into account. For that purpose, used ADAMONT, tool originally developed...
Seasonal prediction uses ensemble forecasting to sample the distribution of possible climate outcomes in upcoming term given slowly-varying constraints on atmosphere. However, translating members’ a seasonal forecast into meaningful information is challenge services are often faced with. When large spread makes difficult interpret, highlighting competing signals from which uncertainty arises may bear added value end users. In order do so, we present an approach extract alternative...
The current Météo-France seasonal prediction system (MF System 8) has 25 members for hindcast from 1993 to 2016 and 51 real-time forecast. In order investigate the benefits of increasing ensemble size within our Copernicus Climate Change Services (C3S) contract, we extended 8 four main start dates (February, May, August, November). We compare forecast skill between official 25-member 51-member hindcast. focus on European region at lead-time 1 next trimester. To describe...

Cet article traite de la prévision des orages sur les Pyrénées en été. Des contrôles ont été effectués par services Météo-France 2002 à l'échelle chaîne pyrénéenne, puis renouvelés et affinés 2003 au niveau départements pyrénéens. Ces fournissent une évaluation performances, possibilités limites ce type prévision. On a examiné, particulier, pertinence critique souvent formulée utilisateurs ces prévisions visant surestimation fréquence journées orageuses.
