For example, citrus growers use wind machines and micro-sprinklers to ensure freezing temperatures don’t ruin the fruit, said Chris Oswalt, a multi-county citrus Extension agent for UF/IFAS Extension Polk and Hillsborough counties.
Wind machines, which increase grove temperatures, work best in windless freezes, Oswalt said. Under such conditions, air above the ground is warmer than it is at the surface.
