• Resumen

  • Recurrent risk of freeze injury to Vitis vinifera vines limits the production to only a few favoured areas of the Niagara Region of southern Ontario. This study examined the characteristics of the inversions that would allow use of wind machines when freezing temperatures were exacerbated under clear calm conditions. The characteristics of the inversions were determined from the temperature data obtained from eight 18.3 m high towers that were established at representative vineyards in the main grape growing area of the region. As a minimum requirement for freeze protection, the temperature at the 18.3 m level was expected to be at least 2°C warmer than the cold air layer at the canopy level.
