Artificial precipitation enhancement aircraft is the best equipment for seeding catalyst in the cloud. What does artificial precipitation mean?

Artificial precipitation enhancement refers to the microphysical process that affects clouds through artificial intervention under suitable weather conditions, so as to achieve the purpose of increasing ground precipitation. The method of artificial precipitation enhancement is to sprinkle catalyst (salt powder, dry ice or silver iodide, etc.). ) enter the cloud, or use sound waves, femtosecond lasers, charged particles and other means to promote the condensation of water, the collision and growth of cloud droplets and other cloud and rain transformation processes. Form precipitation and fall to the ground.

Therefore, artificial precipitation is not equal to artificial precipitation, and the role of catalyst is like "brine tofu". Artificial precipitation enhancement can only play a role when natural clouds meet the conditions of precipitation enhancement.

What does artificial precipitation mean?

Artificial precipitation enhancement is not a panacea for reducing fever. Artificial precipitation enhancement simply means that catalysts such as silver iodide and dry ice are scattered into clouds by airplanes and rockets, resulting in a large number of artificial ice nuclei, which in turn form ice crystals. ? Then grow to a certain extent, and the precipitated particles fall to the ground. But the expression of artificial precipitation is more scientific.

This year, the high temperature and arid areas continue to be controlled by subtropical high, and the macro-and micro-structures of clouds generally do not have the conditions for artificial precipitation enhancement. Under the long-term control of subtropical high, the sky is generally partially cloudy or cloudless at all. The first condition of artificial rainfall is to have clouds, and it is impossible to make clouds artificially. If there were clouds, the temperature would not be so high during the day.

In the absence of clouds, the effect of artificial precipitation enhancement will be very limited. According to the news released by Guiyang, precipitation clouds appeared in some areas of 2 1 Guiyang. Guiyang Meteorological Bureau carried out artificial precipitation enhancement and drought resistance, but it was not enough to "quench thirst". According to the detection and analysis of meteorological radar, it is considered that the overall water content of clouds is not high and the conditions for artificial precipitation enhancement are very limited. After operation, under the joint action of natural precipitation and artificial precipitation, there are 34 rainfall stations monitoring precipitation in * * *, and the measured maximum precipitation is1.7 mm. ..

However, with the arrival of cold air, precipitation occurred in some cities in the Yangtze River basin, which provided an opportunity for artificial precipitation enhancement. Yin Yan said that if the rainy season comes or the cloud system conditions are good, then the natural precipitation may be relatively sufficient. On this basis, adding some artificial ice cores can further increase precipitation.

Affected by rainfall and low-level cold air infiltration, the high temperature weather in Jianghan, Jianghuai and other places was first alleviated. According to the news released by WeChat WeChat official account of Hefei Municipal People's Government on 23rd, with the arrival of rainfall, Feidong County, Chaohu City, Feixi County, Lujiang County and Changfeng County will all choose the opportunity to carry out artificial rainfall. Enhance the operation. Wanzhu District of Wuhu City also stated in the weather modification operation announcement released on the 22nd that it will seize all favorable conditions and continue to carry out artificial precipitation enhancement operations.
