Remember the day of Yang Xiaofang, director of the Linfen Artificial Weather Influence Office

On April 1, after the alarm clock rang at 6 o'clock in the morning, Yang Xiaofang was sleepy, casually opened the Linfen Meteorological APP on her mobile phone, and saw in the real-time monitoring interface that the precipitation cloud system was moving in the direction of Linfen, and her heart was much more solid.

　　Yang Xiaofang is the director of the Municipal Artificial Weather Influence Office (hereinafter referred to as the Film Office). At 9 p.m. on March 31, she was also on duty at the Municipal Meteorological Observatory, analyzing various maps and data from real-time monitoring feedback with forecasters, and discussing with the directors of the meteorological bureaus of Yaodu District, Fushan County, Yicheng County, Xiangfen County and Quwo County about jointly carrying out artificial rain augmentation operations the next day.

　　At 8:00 a.m., a gentle drizzle arrived as scheduled. Nearly 9 o'clock, five pickup trucks carrying artificial rain-increasing rocket launchers arrived at the artificial rain-increasing operation site of the waterlogged river reservoir in Yaodu District.

　　"The precipitation weather process is the primary condition for carrying out artificial rain augmentation operations. The rain-increasing rocket is equipped with silver iodide, and after being launched into the clouds, the water vapor in the cloud will continue to attach to the silver iodide particles, forming a condensation core, and when the condensation core reaches a certain weight, it will form precipitation. Yang Xiaofang further explained to reporters, "There must be clouds before there is rain, and we mainly judge the direction of cloud operation through radar monitoring to enhance the probability of successful implementation of artificial rain increase operations." ”

　　Adjusting the angle of the launcher, loading the rocket, connecting the launcher, in the drizzle, the preparation work before the rain increase operation was rapidly and orderly advanced. "The launch line is connected to the rocket at one end and the launcher at the other, and it must wait until all the links are ready before it can be connected."

　　"Hello, we are the Yaodu District Meteorological Bureau, need to carry out artificial rain increase operations, now apply for airspace, the location is in the waterlogged river reservoir artificial rain increase operation point, the number ×××."

　　"Please wait, I'm inquiring... Approve the one-minute job time, and reply after the job is completed. At 9:33, Zhao Junping, director of the Yaodu District Meteorological Bureau, applied for airspace to the Xi'an Auxiliary Finger Airspace Command Center, which governs the Linfen area, "The launch height of the rain-increasing rocket is about 6,000 meters to 8,000 meters, which will endanger the flight safety of the aircraft, so it is necessary to apply for airspace before each operation." ”

　　Even if it is only a minute, it is a great opportunity for meteorologists who carry out artificial rain augmentation operations. But such luck does not happen every time. On March 26, Zhao Junping led the team to prepare for artificial rain in the same location, from 1 p.m. to 12 p.m. that night, they could not wait for the airspace instructions that could be operated, and they could only return in vain.

　　After the artificial rain increase work at the operation site of the waterlogged river reservoir, 5 vehicles turned around, chased the clouds, and sped away towards the floating mountain. At 10:30, arrived at the Rain Increase Operation Point of Tiantan Mountain in Fushan County, the light rain along the way was gone at this time, and the group could only return to the Fushan County Meteorological Bureau to judge the emergence of the next precipitation process through radar monitoring. "The direction and speed of the clouds are constantly changing, and even close forecasts within two hours cannot be accurately predicted, and the vagaries of nature are its magic." Ma Ruiqing, an engineer of the Xiangfen County Meteorological Bureau who entered the Shanxi Meteorological Business Intranet and participated in the joint operation, answered questions to reporters, "The different colors on the radar puzzle represent different weather, the darker the color, the greater the probability of precipitation, and when it is suitable for artificial rain increase needs to be judged by the combined reflectivity of radar echoes." ”

　　Spring rain is as expensive as oil. "This artificial rain increase operation can effectively increase precipitation, which can play a role in increasing soil moisture, alleviating forest fire pressure, improving air quality, and reducing the occurrence of epidemic diseases." Yang Xiaofang introduced to reporters that since the beginning of this year, the Municipal Film Office has organized a total of 52 artificial rain (snow) operations, of which 4 have been organized to carry out joint rain increase operations, and Linfen Civil Aviation Airport has carried out 10 aircraft rain increase operations.
