The use of artificial precipitation can not only effectively reduce drought, but also extinguish fires. Artificial precipitation is based on the principle of natural precipitation formation, artificially supplementing certain conditions necessary for precipitation formation, promoting the condensation or rapid collision of cloud droplets and their growth into raindrops that fall to the ground.
The method involves selecting the appropriate time according to the physical characteristics of different cloud layers and using planes and rockets to sow catalysts such as dry ice, silver iodide and salt powder in the clouds in order to cause precipitation. or increase the amount of precipitation in clouds to relieve or alleviate the problem. Drought in agricultural lands, increase in the volume of irrigated wateron or the water supply capacity of reservoirs, or increase in the volume of water for electricity production, etc.
Detailed information
Early artificial precipitation had higher requirements for the natural climate. They had to have sufficiently thick clouds, suitable temperature conditions and wind direction, etc. With advances in technology, humans have been able to implement artificial precipitation in various climatic conditions.
There are different precipitation methods for different weather conditions, but the only essential prerequisite is that there is sufficient water vapor in the atmosphere. In other words, clouds in the sky are the best carriers of water vapor. As long as there are enough clouds over arid areas, artificial rain can occur.
However,When the conditions necessary for rain formation are met, artificial precipitation cannot be carried out casually, because artificial precipitation will cause certain side effects on regional ecology. For example, it exacerbates the “rich-poor divide” in water resources between regions. For example, areas located upwind have developed economies and high technological levels. In the event of drought, artificial precipitation is thus produced. use of aerial water resources—— —Clouds, which to some extent intensify drought and water shortages in downwind areas.
The difference between artificial precipitation and artificial precipitation
? People sometimes confuse man-made precipitation with artificial precipitation. In fact, artificial precipitation is differentartificial precipitation. Artificial precipitation is different things, and they are also very different. First of all, they are all artificial, so they are artificial events. In this respect, they are all the same. and artificial precipitation.
? Artificial enhancement of precipitation means that it will still rain in the sky, but people are not very happy with the amount of rain, so they will make changes from the artificial aspect, so it is about artificial enhancement of precipitation, artificial enhancement of precipitation. Rain does not mean that it will not rain, but that it will rain, but the amount of rain is too little. This is the reason why people choose artificial precipitation enhancement. so we can also use this to distinguish between artificial precipitation and precipitationartificial.
?The big difference between artificial precipitation and artificial precipitation enhancement is that artificial precipitation is because the weather is too dry and it hasn't rained, and artificial precipitation is People really can't stand this dry weather and choose artificial precipitation. , so this is actually a big difference between artificial precipitation and artificial precipitation, so we can also clearly understand Artificial precipitation is because the sky cannot rain, and people choose artificial precipitation. This is actually a big difference between artificial precipitation and artificial precipitation, so we can also know this difference.
In fact, we can literally tell the difference between artificial precipitation and artificial precipitation, but they are all dthem artificial actions, so we can also understand this difference in depth. see the difference is very obvious. Artificial precipitation enhancement and artificial precipitation are both different measures.
What is the substance of artificial precipitation?
The difference between artificial precipitationand artificial precipitation is that they have different functions: artificial precipitation is to increase precipitation, while artificial precipitation involves generating precipitation. and the two artificial precipitation methods are different. Artificial precipitation consists of sending rain catalysts (condensation nuclei) into the clouds. Artificial precipitation involves sowing dry ice, silver iodide, salt powder and other catalystssisters. the requirements for the two methods are different.
1. Different effects
Artificial rain enhancement means that it will rain in the sky, but people are not very happy with the amount of rain. , so we're going to make changes from a human perspective, so it's an artificial improvement in precipitation.
The reason for artificial precipitation is that the weather is too dry and it has not rained. People really can't stand this dry weather and choose artificial precipitation.
2. Different methods
Artificial precipitation enhancement involves sending rain-enhancing catalysts (condensation nuclei) into clouds via rockets and other means of transmission to further promote rain in the clouds. Smaller water droplets fall as raindrops, increasingthus affecting the quantity and extent of precipitation.
Artificial precipitation refers to choosing the right time based on the physical characteristics of different cloud layers and using planes and rockets to seed catalysts such as dry ice, silver iodide and salt powder in the clouds to cause precipitation. or increase the amount of cloud precipitation to relieve or alleviate agricultural land drought, increase reservoir irrigation water or water supply capacity, or increase water for power generation .
3. Different conditions are required
Clouds for artificially increasing rainfall must meet three conditions: the thickness of the cloud layer must be more than 2 km; the cloud must have abundant water vapor; there is an updraft zone.
The aboveArtificial pits can only be implemented when rain has fallen or is close to precipitation. They will not work on a sunny day when the sun is shining high.
The substance used in artificial precipitation is dry ice,silver iodide.
1. Dry ice, when vaporized, cools the surrounding layer of air to tens of degrees below zero, causing water droplets to condense.
2, iodizationSilver has a first-rate ability to produce rain. As a chemical substance, silver iodide has extremely low toxicity. Additionally, silver iodide is very effective in producing ice crystals. Usually a cumulus cloud only needs a dozen or so grams. be effective, and the dosage is very low, which is almost negligible and therefore does not cause any pollutionion.
There are two artificial rain methods for spreading coolant. Fire cannons or launch rockets into the clouds.
Artificial precipitation, also known as artificial precipitation enhancement, refers to artificially supplementing certain conditions necessary for precipitation formation based on the principles of natural precipitation formation, promoting the condensation or rapid collision of cloud droplets and their enlargement. into raindrops, which then fall to the ground.
The method is to select the appropriate time according to the physical characteristics of different cloud layers, and use aircraft and rockets to sow dry ice, silver iodide, powder of salt and other catalysts in the clouds in order to cause precipitation or precipitation. increase the quantityprecipitation in clouds to relieve or alleviate the problem Drought in agricultural land, increasing the volume of irrigation water or the water supply capacity of reservoirs, or increasing the volume of water for electricity production, etc. The first experiment with artificial precipitation in China was in 1958. Jilin Province suffered a severe drought unprecedented in 60 years in summer, and artificial precipitation was successful.
