Recently, Yulin City, Shaanxi Province, the Meteorological Bureau completed 5 national ground meteorological observation station weighing sensor construction tasks. This has laid a solid foundation for the winter to carry out a good snow and ice weather forecast service, to further improve the ability of meteorological disaster prevention and mitigation.

The weighing type precipitation sensor is a kind of measuring instrument which is suitable for the measurement of the total amount of precipitation and precipitation intensity in the solid state, liquid state and mixed state. Weighing the completion of the type of precipitation sensor, can improve oilfield, desert and other key areas and snow disaster prone areas of solid-state precipitation automatic continuous observation ability and improve the observation data density and timeliness, Yulin City Meteorological Bureau to carry out good ice and snow weather process of weather forecast and meteorological services to provide strong support, to strengthen the local authorities to cope with heavy snow and ice disaster emergency support capabilities to provide rapid, accurate, real-time dynamic monitoring information support and reduce the effects of snow disaster on the local oil production caused by.

Precipitation observation is one of the main projects of ground meteorological observation. It provides important basic data for weather disaster prevention and reduction, weather forecast, climate analysis and atmospheric science research. Weighing type of precipitation sensor realizes the solid, liquid and mixed precipitation automatic observation, can overcome the meteorological stations in the solid state of artificial precipitation observations resulting from the poor timeliness and observation frequency low defects, to improve the accuracy and efficiency of solid precipitation observation, reduce the workload of staff observation.

Weighing type of precipitation sensor break the status quo artificial solid precipitation observation, the solid precipitation automatic observation, overcomes the manual observation of poor timeliness, accuracy is low, lack of space-time density and can not be comprehensive and reflect the continuous snowfall process changes many drawbacks end, reducing the observatory staff workload, further improve the observation quality of service.
