Joint study of spatial variability of temperatures and wind machine performance in the Quincy vineyard to improve fight against spring frost events

Abstract : Spring frosts occurring after budburst constitute a significant risk for winegrowers and can lead to severe yield losses. Wind machines can contribute to protecting vineyards against these frost events. However, the efficiency of wind machine parks depends on the locations of wind machines concerning their performance and spatial variability of temperature during these frost events. This study aims to characterize wind machine performance and spatial variability of temperature, and propose a methodology for an a priori positioning wind machines on the vineyard of Quincy. To face this stake, the CUMA of Quincy vineyard came up with several partners in the SICTAG project (“Innovant System of Connected decision support and efficient real-time management of wind machine of the Centre Val de Loire”).
