Abstract
Nile valley and delta (the inhabited portion of the vast area of Egypt) is frequently vulnerable to dust storms, which is presumably deemed a potential threat to air quality and human health. We utilized a variety of advanced remote sensing techniques to define, in a high resolution, the domain of land cover change. And using the advantage of the interaction with the Weather Research and Forecasting (WRF) preprocessing system, we apply land cover changes to all the mandatory field of the geographical input in the very early stage of handling inputs. We addressed the impact of land cover change on near-surface moisture and thermal conditions which affect the vertical circulation in the surrounding built environment. We studied the development of cloud formation conditions into precipitation leveraging the abundance of remotely sensed precipitation data sets to conduct a qualitative and quantitative spatial and temporal verification for rainfall. Harnessing the capabilities of the WRF Model coupled with Chemistry (WRF-Chem) we could accurately predict both dust and rain to address the problem of dust cloud interaction. We studied dust-cloud interaction in different phases starting from the cloud activation process forming the very first cloud droplets to the stage when these droplets develop into rain droplets causing the removal of dust, and hence improve the air quality of the areas lying in the course of dust storms
