Abstract:

The study aims to reduce the great threats to the safety of life and property of local residents imposed by the complex terrain of Mentougou District and frequent strong convective weather in local areas. The differences in the precipitation distribution of different terrain were identified before and after the optimization of regional automatic weather stations in Mentougou District. We evaluated the effects of optimized automatic weather stations on rural vitalization and fine meteorological services, and proposed related advices. 26 weather stations were newly introduced between 2018 and 2019, with an average distance of about 7km. The average precipitation in low altitudes was greater than that in middle and high altitude regions during flood seasons in 2006-2017. After the optimization to automatic weather stations, the average precipitation in middle and high altitudes exceeded that in low altitude areas during the flood season in 2018. The weather stations were effective in heavy rainfalls. The effectiveness of these weather stations could be increased by: 1) reinforcing the management of the stations; 2) improving the construction of the stations; 3) strengthening the integrated application of various meteorological methods; and 4) improving the meteorological monitoring system and mechanism. This would promote primary meteorological departments to integrate fine meteorological services into the local rural revitalization strategy, thereby playing a good exemplary role for the meteorological departments throughout the country.

Key words: automatic weather stations, optimization, precipitation, fine service, rural revitalization strategy
