"Rain" is not that simple

Changde Daily reporter 通 Yalin Correspondent Cai Mengge text/picture

There is no windy day without windy days. There is a sun in the sky. In the past month, it has a high temperature and rain, and the earth is thirsty.

Governments and cadres at all levels of Changde are trying to actively carry out production self -rescue. In order to alleviate the drought, a group of "chasing the clouds" dispatched, they stationed in the countryside for 24 hours, and always prepared artificial rainfall ...

In the early morning of August 24th, Changde, who was overwhelming, ushered in the breeze. "The cooling and precipitation is about to come to an end, can the work of the rain come to an end?" The reporter asked. Ji Jingli, deputy head of the business department of the Municipal Meteorological Bureau, replied: "On the contrary, compared to before, there are more suitable operating conditions now, the more we need to seize the opportunity!"

At 11 am, the staff of the Municipal Meteorological Bureau drove to the Zhujiagang of Pantang Town, Taoyuan County to operate the operation and safety work. The operation site is close to the Wang family's reservoir, and a dark green high -fire cannon is set at a fixed set.

Xu Yixiang and Xu Weijian are the operators who are squatting here. They all have experience experience of retired soldiers. They have experienced experience in high -air cannon operation. After joining the job, they have undergone professional training again. During the homework, the two of them conducted a command, a firework, and tacit understanding.

Zhujiagang, Pantang Town, Taoyuan County, the operator demonstrated the operation of high -fired guns.

Near noon, the high -fired cannon was baked by the sun. Xu Yixiang pointed at the artillery body. "It can shoot the shells to 5,000 meters high. But when will the monitor find the appropriate cloud layer notifying us, we apply to the air management department for airspace, and after getting a certain response, we will be answered in 5 minutes after 5 minutes. The internal launch is complete. "He introduced that not every application can pass. During the operation, keep talking with the air management department to ensure that it does not affect flight safety.

It is suitable for people who are suitable for high -fired guns in the magazine, like a magnifying rifle bullet. The cannonball is equipped with a "raining artifact" silver iodide. Once it enters the effective part of the cloud, it can increase the cloud droplets or ice crystals to a certain extent and land to the ground.

"The premise is that there is a certain thickness of rain and clouds, otherwise no cannon has a lot of fire, and it will not be able to reduce the rain." Jing Jing explained that although many citizens and friends are eager to come by a rain, "the clever woman is difficult to cook without rice." During this period, not all clouds have precipitation potential.

Zhujiagang's operating point is a microcosm of the city's meteorological department to strengthen the duty and actively carry out the drought and rain and rain and increase operation. From June 1st to August 23rd, the city's meteorological department operated 49 stops, launched 280 high -firing shells, and 60 rockets. The rainfall of the operating site area has increased significantly, which effectively relieves the drought. From August 23, due to the influence of tropical cyclones, the city's cloud system has increased, and 17 operations teams in the city have gathered again, and they are squatting at 40 operating points around the weather to achieve "guns and rain falls."

These operations are divided into two types: fixed and flowing. The fixed point is equipped with a high -fired gun, and the rocket operating vehicle is dispatched. Yun Jingli introduced, "A job point can control the range of 200 square kilometers, which basically covers the main agricultural production area in the city. The effect of each operation is about 40%of the rainfall. The rain plane has also arrived in Hunan. It is planned to increase frequent operations when the weather conditions are available, so that the rain can fall into Changde more. "
