Document Summary
At night if you don"t have clouds all the heat from the surface is escaping. Created when you have advection, ex: movement of air. Warm water being pushed by strong winds into the cold water. Some methods used for frost dispersion are also used for frost protection. Blow high above orchards and bring warmer air down. The principle of sprinklers is that relatively warm water gives up heat up on contact with the colder air and/or foliage. Stability: when rock a is disturbed, it will return to its original position, rock b however will accelerate away from its original position. If a parcel of air is allowed to rise to a level where it reaches dew point/becomes saturated then a cloud will form. Once the cloud is formed when it continues to develop it already has moisture in it, moisture can condense. Tendency of air to remain in its original position (stable) or rise (unstable)
