Abstract

In this paper, the concept of Thermal Island has been discussed in general. First of all, the definition of the city’s thermal island and its history have been presented using illustrations and diagrams. Next, the climate variables affecting thermal islands have been considered. The purpose of the research is to introduce the city’s thermal island or the point of maximum of heat in the city, which mostly includes the city center. The term “thermal island” refers to the fact that city is warmer than its suburbs and surrounding area, which in some cases can show in a difference in temperature of 5-8 ° C. The research method in the paper is documentary, secondary and with the help of utilization of electronic sources and various websites. In addition, the hypothetical factors that create the cap layer covering the city’s thermal island are mentioned, and the radiation level in the urban area, its comparison with the suburbs and the effects it has on human health and the environment have been studied. Finally, strategies for dealing with Thermal Island through improving public behavior in relation to protecting the environment, developing green space, etc. have been examined and proposed.
