The aim of the current research is to evaluate the effects of urbanization on the temporal and spatial changes of climatic parameters and their relationship. Therefore, the impacts of urbanization on minimum and maximum temperature variations were investigated in Iran's Northwestern urban areas. For this purpose, the meteorological (1987-2017) and urbanization data from the general census as well as the housing population (1365-1395) in conjunction with Pearson Correlation-coefficient and Mann-Kendall Test were used. Based on this test, a positive and significant trend was observed at minimum and maximum temperatures among urban stations. The innovation of this article is in the effect of population increase and physical development of cities on the climatic parameters of cities. Decadal changes show the impact of urbanization on climate. The results of the correlation test between minimum and maximum temperature with the number of population in urban areas are positive. The correlation between the minimum temperature in Khalkhal and Khoramdareh (small towns) was 0.8, in Maragheh and Khoy (average cities) 0.7 and Maximum temperature was 0.61 in Mahabad city and there was a significant relationship between the big cities of Ardebil and Zanjan at 0.7, 0.75, but in Urmia and Tabriz (a large and metropolitan city), the population with a minimal temperature was relatively small, but maximum temperatures in both cities with a coefficient of 0.68, 0.61, indicates the significant role played by the urbanization on urban climate. In small and medium-sized towns, significant changes were observed at minimal temperatures. At all stations, the demographic changes and the minimum and maximum temperature increases were observed.There are many changes in the decades of 1375-1385 and 1385-1395.
