Analyzing the Impact of Buildings on Surrounding Temperature Observational Environment

Observational environment has important influence on accurate observation of meteorological elements. Therefore the study of its effect on meteorological elements is of great significance. This paper simulated the impact of a building on surrounding meteorological environment under neutral stratification condition, stable stratification condition and unstable stratification condition by using City Sub-domain Scale Model (CSSM). The results showed that: With the increase of building height, its impact on surrounding air temperature gradually increased. Under neutral stratification condition, the building exerted the largest effect on surrounding environment. When the initial wind speed reached 10 m/s and the building was as tall as12 m, the impacted distance to leeside could reach 260 m.
