[Edit this paragraph] Ice crystal effect In the cloud with ice crystals and supercooled water droplets, because the saturated water vapor pressure on the ice surface is lower than that on the supercooled water surface, when the actual water vapor pressure in the air is between the two, that is, greater than the saturated water vapor pressure on the ice surface and less than the saturated water vapor pressure on the water surface, the supercooled water droplets will be reduced by evaporation, and water molecules will be continuously transferred from the water droplets to the ice crystals, and the ice crystals will increase due to condensation (as shown in the attached figure). Ice crystals have many opportunities to get along with supercooled water droplets. If the actual vapor pressure at that time is between the saturated vapor pressure of the two, there will be vapor transfer between ice and water. In this case, the actual vapor pressure is less than the saturated vapor pressure of water droplets, which is unsaturated for water droplets and the water droplets will evaporate. However, the actual water vapor pressure is greater than that of ice crystals. If it is too saturated for ice crystals, condensation will occur on them. Therefore, water droplets are constantly evaporating and decreasing, and ice crystals are constantly condensing and increasing. This effect of water vapor transfer between ice water due to the existence of ice water is called ice crystal effect. The degree of ice crystal effect is related to the saturated water vapor pressure difference between water surface and ice surface. The greater the difference, the more significant the ice crystal effect. This effect is one of the important theories of precipitation caused by mixed clouds. See /view/63504.htm for details. Actually, that /question/87579825.html? Si=8 It seems that many things can be made in it. There is an exothermic one with sodium sulfate decahydrate in it.
