Régionalisation d'un indice agro-climatique en Bourgogne

Résumé

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 key development periods of the grape vine. This simulation was performed for the 2003 calendar year which is an “unusual” climate year. Indeed, the warmer weather pattern observed in spring and summer may foreshow for this latitude the effect of climate changes. Our goal is to use this model to assess at regional scale the growing degree days at the date of maturity in 2003 and thus be able to simulate and predict the possible viticultural climatic zoning for the Burgundy region in the future.
