Parameters of urban morphology and its elements such as building mass density as well as the type of direction and width of passages and block structure in addition to climate change, also affect the behavior of citizens, targeting the type of variable change and indexing and the quality of sub-branch communication. Their works are among the most essential analytical provisions. The main purpose is to investigate our relationship between variables affecting the creation of urban climate-micro according to the different morphology of the urban fabric of Tehran metropolis, which is practically not the type of fabric in the form of scenario, which can be referred to our relationship between SVF and urban FAR. In addition, the analysis of the effects of urban morphological parameters on micro-climate variables such as enclosed temperature (T) and mean radiation temperature (mrt) can also show optimal results in the form of parametric study considering the interactions between urban morphology and urban micro-climate. As a result, according to the general analysis and results in the current research, the two groups of the mentioned scenarios have a significant and affected relationship between morphological parameters and variables of urban micro-climate. This research is based on field perception, data and simulation using It is one of the basic software and also energy analysis in the topic of urban climate such as ENVI.met. In addition, the two groups of findings can be expressed in such a simple way that one; The SVF decreases when the BSC is increasing at a constant FAR. In addition, in the case of a sample with a fixed FSI, this factor increases as FAR increases. Enclosed temperature and average radiation temperature are also strongly correlated with urban morphological parameters in the presence of a constant FAR. According to these results, the BSC 25 was the best manifestation of reducing and calming the intensity of the heat island as well as the thermal comfort of the climate during summer nights.
