Will it be raining artificially rainfall?Will it cause a strong convection?Expert answer

In the past two days, artificial rain increase operations in Zhejiang have effectively alleviated high temperature and drought.

Behind artificially raining, what mysteries, we interviewed Shen Wu, an artificially influential weather expert in Zhejiang Province-

What is the principle of artificial rainfall?

The basic principle of artificial rainfall is actually very simple, that is, the catalysts are used through rocket bullets and other methods into the over -cold water areas in the clouds, so that the over -cold water is condensed into small ice crystals and drops, forming rain. For example, a cloud with rich cold water is a warehouse. The meteorological department takes out the cold water from the cloud through technical means. The reason is so simple. So there is no cloud in the sky, we cannot implement artificial rainfall operations.

Will it be raining after artificial rainfall?

This is really not necessarily! After artificial rainfall operations, the phenomenon of rainfall in the cloud will occur. During the landing process, some small ice crystals will evaporate directly, and it cannot reach the ground to achieve effective rainfall. The effective time is about 3 hours, and even 6 hours.

Why can't the main urban area be artificially raining operations?

Usually, we divide the influence area of ​​manual rainfall into two. One is the operating area and the other is the beneficiary area. For some main urban areas, we will not set up a work area in the main urban area due to considering safety issues, but we can use the operation to go through the operation. The downstream effect is to make the urban area benefit as a beneficiary area, and through the precision calculation of our meteorological department, the benefit has been maximized.

Will artificial rain increase the weather?

This answer is: definitely not! The weather phenomenon caused by the strong convection weather is a strong pair of stream. The principle of artificial rain increase operation will not cause the phenomenon of the current. Not only that, if the artificial rain increase operation, if the strong convection weather is encountered, it will also rise to the strong rise. The airflow plays a role in suppressing, just like a highway, a high -speed car will block the wind blowing on the face, but this inhibitory effect is too limited, but the wind has a lot of impact on the driving of the vehicle, so Our artificial rain increase operations will avoid strong streaming areas.
