Sichuan artificial rainfall shells almost hit people in the middle of the road. Has artificial rainfall alleviated the local drought?
Due to the long-term drought in Sichuan, it has a great impact on local agricultural production in Sichuan. Therefore, the Meteorological Monitoring Bureau implemented artificial precipitation enhancement in Sichuan. It is understood that artificial rainfall has been implemented in Mianyang, Zigong, Pingwu Jiangyou Beichuan Anzhou and other places in Sichuan. At present, the rainfall in some places is small to moderate rain, and the rainfall in some places is heavy to heavy rain. This rainfall is very timely to alleviate the drought in Sichuan, and also effectively reduces the forest risk level and the urban ozone environment.
Principle of artificial rainfall
The formation of raindrops is basically that hot and humid water vapor rises and condenses when it is cold, and gradually forms small water droplets or ice crystals. When they accumulate, the updraft will never? A compliment? When they lose their gravity, these small water droplets or ice crystals will break away from the original cumulonimbus clouds and form rainfall.
According to the real-time meteorological environment, the altitude is 4500 meters? After crossing the cloud for 2 hours and 30 minutes at a height of 5000 meters, it returned to the ground safely, and precipitation gradually realized in the working area and its surroundings. According to incomplete statistics, the area of artificial precipitation enhancement is about 600 square kilometers, and the rainfall is obvious, which effectively relieves the drought caused by high temperature in Sichuan Basin.
Warm reminder: if it hasn't rained in our area for a long time, walking outdoors and hearing the roar like shells may be artificial rainfall. At this time, it is best not to walk outdoors, but to shelter from the rain indoors for the time being.
