Rainfall radar-area
Dalian new generation weather radar station project, located in Nanshan, 200 meters above sea level in Dalian city, is not only a meteorological project, but also one of Dalian's landmark buildings and lighting projects. The whole project will be completed in June+10 this year. The person in charge of the Construction Committee said that compared with the 14 radar renderings built and under construction in China, Dalian New Generation Weather Radar Station is undoubtedly the most beautiful.
Longwangshan Park in Nanjing, on the top of the mountain at an altitude of 132 meters, a 30-meter-high silver-white building rises like an exaggerated shape of a tower, attracting attention. This new building is the top rain radar building in China which will be completed soon. On the roof of the radar building, a "giant glass ball" with a diameter of 12 meters and shining in the sun is even more amazing! According to Wang, an engineer from the Meteorological Observatory, this "glass ball" is the "advanced bedroom" of this rain radar, and the cost is130,000 yuan. Walking into the radar "bedroom", you can see the giant radar like Dapeng spreading its wings. The top radar monitoring range is 460 kilometers in diameter, and the cloud and rain areas over Suzhou, Xuzhou and Wuxi are all within its observation range. After calculation, it is inferred that there is a rainy area over Maanshan, Anhui Province. Because the rain particles in the cloud conduct electricity, their reflection frequency is different from that in the atmosphere, so we can know the rain situation by the color and position of the reflected bright spots on the screen. Because Nanjing is prone to thunderstorms every summer, the rain radar can do it three hours before the thunderstorm breaks out.
Forecast the time and place of rainfall with rain radar; In winter, when rain and snow come, it can send out disastrous weather warnings to aviation, water transport and agriculture departments.
The domestic top rain radar with a total value of more than 57 million yuan has been "settled" in Rongcheng since 2003. The planning and design of radar "appeared" in Sichuan Meteorological Bureau. In the compound of the Provincial Meteorological Bureau, there stands a 95-meter-high tower with a huge "glass ball" at the top. The diameter of "glass ball" is12m, which is the bedroom of "Rain Radar". This glass ball weighs 12 ton, and it is all made of FRP. Its monitoring range radius reaches 450 kilometers. Especially in the measurement range with a radius less than 200 kilometers, the intensity and rainfall of each precipitation process can be estimated more accurately.
The special financial fund of 600,000 yuan in Tonghua City, Jilin Province has been settled in the Municipal Meteorological Bureau to strengthen the construction of rainfall radar station in Tonghua City. Tuodaoling Microwave Station is 967 meters above sea level, and the municipal finance invested 600,000 yuan to build a rain radar station.
The large antenna of 500 kg weather radar was successfully hoisted on the tower frame on the eighth floor of Deqing Meteorological Bureau. This is a small 7 1 1 meteorological rain radar invested by Deqing county government this year.
