The Multi-Scale Numerical Modeling System for Research on the Relationship between Urban Planning and Meteorological Environment


doi: 10.1007/BF02915684

  • Considering the urban characteristics,a customized multi-scale numerical modeling system is established to simulate the urban meteorological environment.The system mainly involves three spatial scales:the urban scale,urban sub-domain scale,and single to few buildings scale.In it,different underlying surface types axe employed,the building drag factor is used to replace its roughness in the influence on the urban wind field,the effects of building distribution,azimuth and screening of shortwave radiation are added,and the influence of anthropogenic heating is also taken into account.All the numerical tests indicate that the simulated results are reasonably in agreement with the observational data,so the system can be used to simulate the urban meteorological environment.Making use of it,the characteristics of the meteorological environment from the urban to urban sub-domain scales,even the among-buildings scale,can be recognized.As long as the urban planning scheme is given,the corresponding simulated results can be obtained so as to meet the need of optimizing urban planning.
