at 15:30 on August 30, Sichuan meteorological station issued a blue rainstorm warning. This short message, which affected people, is the result of 24-hour shift work of many weather forecasters. Before that, LV Xuedong, the chief forecaster of the provincial meteorological station, looked around in front of different computer screens. After analyzing cloud charts, wind charts, rainfall charts and various data, he signed his name on the weather warning notice to confirm the content of the blue rainstorm warning to be issued soon. Since the flood season of

, meteorological departments at all levels in Sichuan have issued 5901 warning and warning signals for rainstorm, high temperature and lightning, with 72.26 million short messages. When extreme weather comes, we will receive meteorological disaster warning in advance on our mobile phone. Many people do not know that in the sky and underground, there are many pairs of “eyes” monitoring the weather information in the sky.

are the busiest time for weather forecasters every year in the flood season. In case of severe convective weather, in addition to going to the toilet and eating, the rest of the time is staring at the display screen intensely, for fear of missing a satellite cloud image and missing a meteorological data. In case of sudden weather conditions, they are basically sleepless all night. Nowadays, in order to forecast the weather more accurately, forecasters use weather satellites, weather radars and ground weather stations to “feel” the sky and the earth. There are 24-hour meteorological satellites in the earth’s atmosphere. Through the ground satellite station, the electrical signals from the satellite can be recovered and mapped into various clouds, wind speeds and wind directions. After further processing and calculation, various meteorological data can be obtained. Since March 25 this year, 11 Doppler weather radars in the province have entered the 24-hour flood season operation mode ahead of schedule. Known as the “thousand mile eye”, it uses its “pot shaped” antenna to rotate and send out radio waves, and at the same time receives weak waves reflected from wind, cloud and rain, forming the outline of wind, cloud and rain on the computer. The 24-hour continuous rotation of

is the normal work of Wenjiang national climate station in Bajiao community, Yongning Street, Wenjiang District, Chengdu. The data returned by photoelectric digital sunshine meter, precipitation sensor, visibility meter, precipitation weather observation instrument and other equipment are displaying real-time data on the display and updating every minute. These data will be timely collected to the data platform of Sichuan Meteorological Bureau and the National Meteorological Center through wireless transmission, providing strong support for the next weather forecast.

have been very curious about the sky since ancient times. Today, human beings have changed their lives with technology and changed the way of “feeling” the sky and the “hole”. Our meteorologists have initially established a three-dimensional meteorological monitoring network of the sky, the air and the earth, and their ability to monitor and warn meteorological disasters has been significantly improved.
