Behind the drought and germination of mannations: the drone and the high gun are on the battlefield to the rain to "reject"

Cover reporter Wu Bingqing

On the morning of August 26, Chengdu people felt the long -lost coolness.

Liang comes from the rain. From 20:00 to 7:00 on August 25th, there were obvious thunderstorms in many parts of Chengdu. There were a total of 161 stations in light rain, 97 stations in rainstorms, 65 stations in heavy rain, and 7 stations in heavy rain.

After continuous high temperature and sunny, I look forward to a cooling rain, and many people are lamenting "long drought and glyphs". In fact, this mani dew is not only "God of God", but also artificial efforts.

Two drones support the accumulated flight for 380 minutes to "urge" rain to the cloud

"So hot, why not rainfall artificially?" This summer, many people issued such questions. Earlier, the meteorological department also responded that artificial rainfall needs to be at the right time in order to turn the cloud into rain, and this cloud.

Recently, such a cloud has come. The reporter learned that the "occupation" Sichuan Basin's long -term subtropical high -pressure exit, and the cold air in the north was active. The Sichuan Basin, which was originally "clear sky", had a cloud that could bring rainfall.

In order to make the rain even more "happy", the power of technology was dispatched.

At 12:46 on August 25, an aviation industry pterosaur-2H drone took off from Hongyuan Airport of Hongyuan Airport in the Aba Tibetan Qiang Autonomous Prefecture in Sichuan Province. A TB-A drone took off from Zigong Fengming Airport, and carried out rain increase operations in the area near Neijiang.

Behind these two drones and rainfall operations are many special conferences of the China Meteorological Administration's artificial impact weather center and the Sichuan Meteorological Administration. "Large drones can carry out large -scale rainfall operations under complex terrain and landforms and meteorological conditions." Said the staff of the Sichuan Province artificially influencing weather office (hereinafter referred to as "Sichuan Province Film Office") said.

The drone flew to the high altitude with 20 silver flames. The ground staff can observe the cloud volume status of the drone where the drone is located on the ground through cloud physical detection equipment. Then issue instructions to start catalytic sowing equipment to ignite iodide flames. "Silver iodide can promote the transformation of ice water in the cloud, thereby increasing precipitation," said the staff member.

On the 25th, the two drones had a total of 6 hours and 20 minutes, the total range was about 1900 kilometers, and the operating area reached 6,600 square kilometers.

In addition to the drone, at 12:25 on August 26, the staff of the Film Office also took the plane and flew to the high altitude to carry out rain increase operations in Guangyuan, Mianyang, Deyang and other places in the north of the basin.

In various ways, "seeking" the rain on the 26th in the morning, the basin ushered in many long -lost coolness

The reporter learned that artificial rainfall also includes rockets and high gun operations and ground smoke furnace operations. They have their own advantages and can complement each other.

Compared with airplane operations, rockets and cannons can spread catalysts into a strong convection cloud that is difficult to enter by aircraft. Ground smoke furnaces are often used in the operation of mountainous cloud cloud. In addition, this method is also very suitable for cities and surrounding areas that are difficult or unable to apply for operating airspace permits. In the process of "seeking rain", Sichuan used all methods.

The reporter learned from the Sichuan Provincial Film Office that on August 24-25, with the strong support of the airspace control department, the province carried out air and ground three-dimensional artificial rainfall operations, implemented 2 drone rainfall operations, and ground rain increase 103 batches of homework, covering Chengdu, Deyang, Mianyang, Guangyuan, Meishan, Leshan, Bazhong, Dazhou, Zijiang, Zigong, Luzhou, Yibin, Aba and other cities (states). The operation of the operation was universal, and heavy rain in some areas. In order to prevent hail disasters, Panzhihua and Liangshan carried out 266 batches of ground hail prevention operations.

On the morning of the 26th, except for the east of the basin, most of the other cities in the basin waited for the long -lost coolness after the rain. The reporter learned that at present, Sichuan's artificial rain increase work will continue, and the staff of the Film Office is still waiting to see the opportunity to see the opportunity and Huayun into rain.
