Under the global warming, the significant changes in atmospheric water cycle lead to drying in arid region, which is strengthening the effect of aerosol on Fog-Haze generation and accelerating the emergence of infectious diseases. However, the production process of the Fog-Haze is lack of quantitative description based on atmospheric water cycle. In this paper, we modeled the process of Fog-Haze generation, evolution and disappearance fundamentally and theoretically. The budget functions for water vapor and aerosol were coupled by the physical and chemical interaction between water vapor and aerosol. The obtained results may provide new insights on the control of Fog-Haze and the related infectious diseases induced by Fog-Haze. (C) 2017 Published by Elsevier Ltd.
