Heating artificially!Ningbo are arranged in these places

Following 6:00 on July 15, after the Ningbo Meteorological Observatory issued a hot summer alert, as of 9:00, Ningbo issued a high -temperature orange warning across the region.

The weather is so hot, can you reduce the rainfall to cool down? Ningbo will seek rain and rain.

The Ningbo People's Film Office released news that on July 15-18, according to weather and airspace conditions, in Lizhou Street, Yuyao City, Dawyan Town, Fenghua District, and Huangtan Town, Ninghai County organized artificial rain-raising rocket operations, in Yuyao Shi Lizhou Street, Xikou Town, Fenghua District, and Shenxian Town, Ninghai County carried out artificial rain furnace operations.

Why are these places "manually raining" during this time?

The meteorological department should carry out artificial rainfall operations according to the needs of society. For example, in addition to the continuous sunny heat and high temperature, agricultural drought, environmental pollution, and high forest fire risk levels, they must also meet certain natural conditions. It should be known that "artificial rainfall" is not "artificial rainfall", and not all clouds can turn into rain. Like the light and white clouds commonly common in summer, it cannot be turned into rainwater through manual influence.

Generally speaking, when the thickness of the cloud is more than two kilometers, the lack of ice crystals has rich water vapor, and there is still sufficient water vapor to continuously supply the outside of the cloud body to pass the "review".

In the process of natural precipitation, when the ascending airflow drives the warm and humid air to rise rapidly, the air cools with the height increase, and the water vapor condenses into small water droplets and continuously merge the collision increase. The artificially affect weather operation is when the timing is mature. By launching a rocket or high -mountain smoke furnace, artificially send the catalyst to the cloud layer, and promote the rapid assembly of small water droplets to form large water droplets. Water vapor "point" into rain drops, thereby achieving the effect of increasing precipitation.

In other words, artificial rainfall operations are not the meteorological department to make rainstorms, but when there are precipitation conditions, use some "means" to make it bigger.

From the perspective of the weather situation, after the 15th, Ningbo's subtropical high pressure weakened eastward, and the water vapor turned to the cloud system to increase the number of operating conditions of artificial rainfall.

Finally, in addition to meeting the above conditions, artificial rain increases to meet certain ground conditions. The population density in the city center does not have the conditions for artificial rainfall operations.
