Régionalisation d'un indice agro-climatique en Bourgogne

2009

National audience; Global climate change affects not only common farm crops, but also vineyard yields, the effects of which are commonly observed in both the phenological stages of the vine and the features of the finished product. Vine production is strongly affected by local climate variation. Unfortunately, General Atmospheric Circulation Models are lacking to accurately reproduce useful local climate pattern. The use of Regional Atmosphere Circulation Models offers a great opportunity towards climate impact studies. In this paper, we assess the ability of the WRF (Weather Research and Forecasting) regional climate model to reproduce climate variability in the Burgundy region during the …

Évaluation de la réserve en eau à l'échelle des pédopaysages de Bourgogne

2009

National audience; L'étude porte sur l'adaptation au changement climatique en Bourgogne. Elle vise à définir la sensibilité de la ressource en eau des territoires Bourguignons à ces évolutions climatiques et à en estimer les incidences par secteurs géographiques et d'activité. Ce projet pluri-disciplaire a été mis en place par Alterre Bourgogne dont la tache a été de fédérer un réseau d'acteurs régionaux aux compétences variées : climatologie, pédologie et hydrologie. La première étape, présentée ici, a consisté à estimer la capacité des sols à stocker de l'eau, c'est-à-dire à calculer la taille de leur réserve utile. Ces calculs ont été réalisés à partir du référentiel pédologique de Bourg…

Spatial analysis of within-vineyard grape vine sensitivity to solar irradiance patterns. A case study using pinot noir in a complex terrain

2009

14225; International audience; We analyze how the patterns of the solar irradiance affect the growth of Pinot noir grapevines at stand-scale over a hilly terrain bounded by a coniferous forest. The study area is located on the “Vineyard Cost” that produce some of the best wines of the Burgundy region. The work is based on i) a Geographical Information Systems (GIS) and ii) the joint use of both irradiance and phenological models. Results show that the patterns of irradiance deficit are the primary driving force of the growth. Linear trends display good correlation between the total deficit of irradiance, and the developped growth index (R2 up to 0.96). Trends appear strongly modulated by posit…

West African Monsoon Water Cycle : Assessment of numerical weather prediction water budgets

2009

This study investigates the atmospheric water cycle over West Africa at seasonal and intraseasonal timescales during AMMA Extended Observing Period (2005 to 2007). It aims at characterizing the scales of variability and inter-relations of atmospheric water budget terms and the underlying processes. The regional-scale moisture budget is examined using Numerical Weather Prediction (NWP) models and elaborate products. The latter are: TRMM 3B42v6 satellite precipitation estimates and evapo-transpiration estimates produced by land surface models (ALMIP project). These products allow for a comprehensive description of the water budget. NWP models provide also their own complete description of the…
