Extremos térmicos e vulnerabilidade num vinhedo do entre douro e Minho

Abstract

Climatic extremes and vulnerability on an entre douro e minho vineyard. The carrying out of fine scale measurements on an Entre Douro e Minho vineyard permitted the observation of extreme temperatures that can be the cause of damages for the vine. It was noticed a strong spatial variation of temperatures, generated by the surface characteristics (topography, soil occupation, etc.). Hazard charts of "minimum and maximum temperatures" were produced from a considerable amount of data, obtained on a microclimatic scale.
