Variabilité spatiotemporelle des températures aux échelles fines dans le vignoble de Vinho verde (Portugal) dans un contexte de changement climatique

In the Entre Douro e Minho area (North of Portugal), an agroclimatologic study is made in two distant soils of wine of a few kilometres and from which the topographic characteristics and the variety of vine are different. A climatic study on fine scales is carried out in order to determine the local influence of the surface characteristics on the weather parameters. The temperature measurements and the agronomic analysis carried out between February and April 2003 showed a strong space-time variability of the spring frost risk between the two sites and inside even of the soils. In a context of climate change, this type of climatic study in fine scales must be taken into account to ameliorate simulation and predictions

Mesures climatiques aux échelles fines (météorologiques et agronomiques) et variabilité spatiale du gel printanier dans le vignoble de Vinho Verde (Portugal)

In the Entre Douro e Minho area (North of Portugal)two distant vineyards (which different topography and grapes are studed from a agroclimatological perspective. The objective is to determine the optimal topoclimatic conditions for the culture of the vine. A climatic study on fine scales is carried out in order to determine the local influence of the surface characteristics on the weather parameters. The temperature measurements and the agronomic analysis carried out between February and April 2003 showed a strong space-time variability of the spring frost risk between the two sites and inside even of the soils

A pertinência dos estudos de microclimatologia para a prevenção dos riscos climáticos num vinhedo do "Entre Douro e Minho" : estação vitivinícola Amândio Galhano

Enquadrado nas ciências geocindínicas, o estudo relacionou o hazard (clima) e a vulnerabilidade da população-alvo (videiras). Realizou-se assim, uma análise da variação espacio-temporal do elemento climático temperatura e suas consequências no adequado desenvolvimento das videiras, com o intuito de diagnosticar os factores de risco associados aos extremos térmicos e contribuir para a definição das suas áreas de risco na EVAG. Fez-se também um breve estudo da distribuição espacial da humidade relativa e da evaporação. Finalmente, esboçou-se um modelo espacial para definir as áreas de risco/hazard dos extremos térmicos
