Increasing aerosol concentration in the atmosphere due to urbanization is considered to act as a condensation nucleus inside clouds causing rainfall and elevated air currents near buildings. Air pollutants are the main source of aerosol. Aerosol is not only related to air pollution, but also to weather, as it affects cloud development. Aerosol acts as a condensation nucleus, a seed that helps vapor clump together to form clouds. Therefore, if the concentration of aerosol increases, the probability of cloud formation increases. In this study, we have found that air pollutants affect the solution effect and curvature effect, acting as a better condensation nucleus than NaCl, a natural condensation nucleus. We found this by measuring the surface tensions and performing condensation experiments. Therefore, it is speculated that aerosol also plays an important role in the climate change model. In this study, by examining the properties of aerosol, we were able to better understand the properties of air pollutants. Also, by examining how air pollutants affect the growth of cloud droplets from analyzing the rain of different parts of certain regions, we investigated how air pollutants affect the formation of smog and clouds. But, further research to relate precipitation efficiency is necessary.
