How the Cold Air Drain® Works
Radiation frosts occur during clear, cold nights with no wind. The ground loses heat stored during the day allowing an inversion layer to develop. In an inversion, the warmer air layer sits above the cold air layer that is closest to the ground.
During a radiation frost night, the heaviest cold air molecules flow downhill, like water, due to gravity. This cold air settles in low elevation areas that do not allow for adequate drainage. As the cold air accumulates in an area, frost damage occurs.
The Cold Air Drain® thrusts the cold air upward to a height of nearly 300ft (91.44m). As the coldest air is being sent up, it collects and mixes with the warmer, lighter air from above. This helps to give the cold air continuous lift and allows it to rise higher, until it is dispersed into the upper inversion layer. The coldest air layer is drained and will not fall back down.
The Cold Air Drain® effect changes the temperature in the lower elevation, frost-prone areas to be more similar to the temperatures in the higher elevation, non-frost areas. The grower may expect a more consistent yield in the lower and higher elevation areas.
